1 - Release Notes

This section includes release notes for supported W&B Server releases. For releases that are no longer supported, refer to Archived releases.

 RSS feed

1.1 - Release policies and processes

This page gives details about W&B Server releases and W&B’s release policies. This page relates to W&B Dedicated Cloud and Self-Managed deployments. To learn more about an individual W&B Server release, refer to W&B release notes.

W&B fully manages W&B Multi-tenant Cloud and the details in this page do not apply.

Release support and end of life policy

W&B supports a major W&B Server release for 6 months from its initial release date.

• Dedicated Cloud instances are automatically updated to maintain support.

• Customers with Self-managed instances are responsible for upgrading in time to maintain support. Avoid staying on an unsupported version.

  W&B strongly recommends customers with Self-managed instances to update their deployments with the latest release at minimum once per quarter to maintain support and receive the latest features, performance improvements, and fixes.

Release types and frequencies

• Major releases are produced monthly, and may include new features, enhancements, performance improvements, medium and low severity bug fixes, and deprecations. An example of a major release is 0.68.0.
• Patch releases within a major version are produced as needed, and include critical and high severity bug fixes. An example of a patch release is 0.67.1.

Release rollout

1. After testing and validation are complete, a release is first rolled out to all Dedicated Cloud instances to keep them fully updated.
2. After additional observation, the release is published, and Self-managed deployments can upgrade to it on their own schedule, and are responsible for upgrading in time to comply with the Release support and End of Life (EOL) policy. Learn more about upgrading W&B Server.

Downtime during upgrades

• When a Dedicated Cloud instance is upgraded, downtime is generally not expected, but may occur in certain situations:
  • If a new feature or enhancement requires changes to the underlying infrastructure, such as compute, storage or network.
  • To roll out a critical infrastructure change such as a security fix.
  • If the instance’s current version has reached its End of Life (EOL) and is upgraded by W&B to maintain support.
• For Self-managed deployments, the customer is responsible for implementing a rolling update process that meets their service level objectives (SLOs), such as by running W&B Server on Kubernetes.

Feature availability

After installing or upgrading, certain features may not be immediately available.

Enterprise features

An Enterprise license includes support for important security capabilities and other enterprise-friendly functionality. Some advanced features require an Enterprise license.

• Dedicated Cloud includes an Enterprise license and no action is required.
• On Self-managed deployments, features that require an Enterprise license are not available until it is set. To learn more or obtain an Enterprise license, refer to Obtain your W&B Server license.

Private preview and opt-in features

Most features are available immediately after installing or upgrading W&B Server. The W&B team must enable certain features before you can use them in your instance.

• Private preview: W&B invites design partners and early adopters to test these features and provide feedback. Private preview features are not recommended for production environments.

  The W&B team must enable a private preview feature for your instance before you can use it. Public documentation is not available; instructions are provided directly. Interfaces and APIs may change, and the feature may not be fully implemented.

• Public preview: Contact W&B to opt in to a public preview to try it out before it is generally available.

  The W&B team must enable a public preview feature before you can use it in your instance. Documentation may not be complete, interfaces and APIs may change, and the feature may not be fully implemented.

To learn more about an individual W&B Server release, including any limitations, refer to W&B Release notes.

1.2 - 0.68.0

W&B Server v0.68 includes enhancements to various types of panels and visualizations, security improvements for Registry, Weave, and service accounts, performance improvements when forking and rewinding runs, and more.

Features

• Release notes for W&B Server are now published in the W&B documentation in addition to on GitHub. Subscribe using RSS.
• Registry admins can define and assign protected aliases to represent key stages of your development pipeline. A protected alias can be assigned only by a registry admin. W&B blocks other users from adding or removing protected aliases from versions in a registry using the API or UI.
• You can now filter console logs based on a run’s x_label value. During distributed training, this optional parameter tracks the node that logged the run.
• You can now move runs between Groups, one by one or in bulk. Also, you can now create new Groups after the initial logging time.
• Line plots now support synchronized zooming mode, where zooming to a given range on one plot automatically zooms into the same range on all other line plots with a common x-axis. Turn this on in the workspace display settings for line plots.
• Line plots now support formatting custom metrics as timestamps. This is useful when synchronizing or uploading runs from a different system.
• You can now slide through media panels using non-_step fields such as epoch or train/global_step (or anything else).
• In Tables and plots in Query Panels that use runs or runs.history expressions, a step slider allows you to step through the progress on your metrics, text, or media through the course of your runs. The slider supports stepping through non-_step metrics.
• You can now customize bar chart labels using a font size control.

Private preview

Private preview features are available by invitation only. To request enrollment in a private preview, contact support or your AISE.

• Personal workspace templates allow you to save your workspace setup so it is automatically applied to your new projects. Initially, you can configure certain line plot settings such as the default X axis metric, smoothing algorithm, and smoothing factor.
• Improved Exponentially-weighted Moving Average (EMA) smoothing provides more reliable smoothed lines when operating on complete, unbinned data. In most cases, smoothing is handled at the back end for improved performance.

Weave

• Chat with fine-tuned models from within your W&B instance. Playground is now supported in Dedicated Cloud. Playground is a chat interface for comparing different LLMs on historical traces. Admins can add API keys to different model providers or hook up custom hosted LLM providers so your team can interact with them from within Weave.
• Open Telemetry Support. Now you can log traces via OpenTelemetry (OTel). Learn more.
• Weave tracing has new framework integrations: CrewAI, OpenAI’s Agent SDK, DSPy 2.x and Google’s genai Python SDK.
• Playground supports new OpenAI models: GPT‑4.1, GPT‑4.1 mini, and GPT‑4.1 nano.
• Build labeled datasets directly from traces, with your annotations automatically converted into dataset columns. Learn more.

Security

• Registry admins can now designate a service account in a registry as either a Registry Admin or a Member. Previously, the service account’s role was always Registry Admin. Learn more.

Performance

• Improved the performance of many workspace interactions, particularly in large workspaces. For example, expanding sections and using the run selector are significantly more responsive.

• Improved Fork and Rewind Performance.

  Forking a run creates a new run that uses the same configuration as an existing run. Changes to the forked run do not the parent run, and vice versa. A pointer is maintained between the forked run and the parent. Rewinding a run lets you log new data from that point in time without losing the existing data.

  In projects with many nested forks, forking new runs is now much more efficient due to improvements in caching.

Fixes

• Fixed a bug that could prevent an organization service account from being added to new teams.
• Fixed a bug that could cause hover marks to be missing for grouped lines.
• Fixed a bug that could include invalid project names in the Import dropdown of a Report panel.
• Fixed a display bug in the alignment of filters in the run selector.
• Fixed a page crash when adding a timestamp Within Last filter
• Fixed a bug that could prevent the X-axis from being set to Wall Time in global line plot settings.
• Fixed a bug that could prevent image captions from appearing when they are logged to a Table.
• Fixed a bug that could prevent sparse metrics from showing up in panels.
• In Run Overview pages, the Description field is now named Notes.

1.3 - 0.67.0

Features

• In Reports, you can now give a run a custom display name per panel grid. This allows you to replace the run’s (often long and opaque) training-time name with one that is more meaningful to your audience. The report updates the name in all panel grids, helping you to explain your hard-won experimental insights to your colleagues in a concise and readable way. The original run name remain intact in the project, so doing this won’t disrupt your collaborators.
• When you expand a panel in the workspace, it now opens in full screen mode with more space. In this view, line plots now render with more granular detail, using up 10,000 bins. The run selector appear next to the panel, letting you easily toggle, group, or filter runs in context.
• From any panel, you can now copy a unique URL that links directly to that panel’s full screen view. This makes it even easier to share a link to dig into interesting or pathological patterns in your plots.
• Run Comparer is a powerful tool you can use to compare the configurations and key metrics of important runs alongside their loss curves. Run Comparer has been updated:
  • Faster to add a Run Comparer panel, as an expanded option in Add Panels.
  • By default, a Run Comparer panel takes up more space, so you can see the values right away.
  • Improved readability and legibility of a Run Comparer panel. You can use new controls to quickly change row and column sizes so you can read long or nested values.
  • You can copy any value in the panel to your clipboard with a single click.
  • You can search keys with regular expressions to quickly find exactly the subset of metrics you want to compare across. Your search history is saved to help you iterate efficiently between views.
  • Run Comparer is now more reliable at scale, and handles larger workspaces more efficiently, reducing the likelihood of poor performance or a crashed panel.
• Segmentation mask controls have been updated:
  • You can now toggle each mask type on or off in bulk, or toggle all masks or all images on or off.
  • You can now change each class’s assigned color, helping to avoid confusion if multiple classes use the same color.
• When you open a media panel in full screen mode, you can now use the left or right arrows on your keyboard to step through the images, without first clicking on the step slider.
• Media panels now color run names, matching the run selector. This makes it easier to associate a run’s media values with related metrics and plots.
• In the run selector, you can now filter by whether a run has certain media key or not.
• You can now move runs between groups in the W&B App UI, and you can create new groups after the run is logged.
• Automations can now be edited in the UI
• An automation can now notify a Slack channel for artifact events. When creating an automation, select “Slack notification” for the Action type.
• Registry now supports global search by default, allowing you to search across all registries by registry name, collection name, alias, or tag.
• In Tables and Query panels that use the runs expression, you can use the new Runs History step slider and drop-down controls to view a table of metrics at each step of a run.
• Playground in Weave supports new models: OpenAI’s gpt-4.5-preview and Deepseek’s deepseek-chat and deepseek-reasoner.
• Weave tracing has two new agent framework integrations: CrewAI and OpenAI’s Agent SDK.
• In the Weave UI, you can now build Datasets from traces. Learn more: https://weave-docs.wandb.ai/guides/core-types/datasets#create-edit-and-delete-a-dataset-in-the-ui
• The Weave Python SDK now provides a way to filter the inputs and outputs of your Weave data to ensure sensitive data does not leave your network perimeter. You can configure to redact sensitive data. Learn more: https://weave-docs.wandb.ai/guides/tracking/redact-pii/
• To streamline your experience, the System tab in the individual run workspace view will be removed in an upcoming release. View full information about system metrics in the System section of the workspace. For questions, contact support@wandb.com.

Security

• golang crypto has been upgraded to v0.36.0.
• golang oauth2 has been upgraded to v0.28.0.
• In Weave, pyarrow is now pinned to v17.0.0.

Performance

• Frontend updates significantly reduce workspace reload times by storing essential data in the browser cache across visits. The update optimizes loading of saved views, metric names, the run selector, run counts, W&B’s configuration details, and the recomputation of workspace views.
• Registry overview pages now load significantly faster.
• Improved the performance of selecting metrics for the X, Y, or Z values in a scatter plot in a workspace with thousands of runs or hundreds of metrics.
• Performance improvements to Weave evaluation logging.

Fixes

• Fixed a bug in Reports where following a link to a section in the report would not open to that section.
• Improved the behavior of how Gaussian smoothing handles index reflection, matching SciPy’s default “reflect” mode.
• A Report comment link sent via email now opens directly to the comment.
• Fixed a bug that could crash a workspace if a sweep takes longer than 2 billion compute seconds by changing the variable type for sweep compute seconds to int64 rather than int32.
• Fixed display bugs that could occur when a report included multiple run sets.
• Fixed a bug where panels Quick Added to an alphabetically sorted section were sorted incorrectly.
• Fixed a bug that generated malformed user invitation links.

1.4 - 0.66.0

Features

• In tables and query panels, columns you derive from other columns now persist, so you can use them for filtering or in query panel plots.

Security

• Limited the maximum depth for a GraphQL document to 20.
• Upgraded pyarrow to v17.0.0.

1.5 - 0.65.0

Features

• From a registry’s Settings, you can now update the owner to a different user with the Admin role. Select Owner from the user’s Role menu.
• You can now move a run to a different group in the same project. Hover over a run in the run list, click the three-vertical-dots menu, and choose Move to another group.
• You can now configure whether the Log Scale setting for line plots is enabled by default at the level of the workspace or section.
  • To configure the behavior for a workspace, click the action ... menu for the workspace, click Line plots, then toggle Log scale for the X or Y axis.
  • To configure the behavior for a section, click the gear icon for the section, then toggle Log scale for the X or Y axis.

1.6 - 0.63.0

Features

Weave is now generally available (GA) in Dedicated Cloud on AWS. Reach out to your W&B team if your teams are looking to build Generative AI apps with confidence and putting those in production.

The release includes the following additional updates:

• W&B Models now seamlessly integrates with Azure public cloud. You could now create a Dedicated Cloud instance in an Azure region directly from your Azure subscription and manage it as an Azure ISV resource. This integration is in private preview.
• Enable automations at the Registry level to monitor changes and events across all collections in the registry and trigger actions accordingly. This eliminates the need to configure separate webhooks and automations for individual collections.
• Ability to assign x_label, e.g. node-0, in run settings object to distinguish logs and metrics by label, e.g. node, in distributed runs. Enables grouping system metrics and console logs by label for visualization in the workspace.
• Coming soon with a patch release this week, you will be able to use organization-level service accounts to automate your W&B workloads across all teams in your instance. You would still be able to use existing team-level service accounts if you would like more control over the access scope of a service account.
  • Allow org-level service accounts to interact with Registry. Such service accounts can be invited to a registry using the invite modal and are displayed in the members table along with respective organization roles.

Fixes

• Fixed an issue where users creating custom roles including the Create Artifact permission were not able to log artifacts to a project.
• Fixed the issue with metadata logging for files in instances that have subpath support configured for BYOB.
• Block webhook deletion if used by organization registry automations.

1.7 - Archived Releases

Archived releases have reached end of life and are no longer supported. A major release and its patches are supported for six months from the initial release date. Release notes for archived releases are provided for historical purposes. For supported releases, refer to Releases.

1.7.1 - 0.61.0

Features

This is a mini-feature and patch release, delivered at a different schedule than the monthly W&B server major releases

• Organization admins can now configure Models seats and access control for both Models & Weave in a seamless manner from their organization dashboard. This change allows for a efficient user management when Weave is enabled for a Dedicated Cloud or Self-managed instance.
  • Weave pricing is consumption-based rather than based on number of seats used. Seat management only applies to the Models product.
• You can now configure access roles at the project level for team and restricted scoped projects. It allows assigning different access roles to a user within different projects in the same team, and thus adding another strong control to conform to enterprise governance needs.

Fixes

• Fixed an issue where underlying database schema changes as part of release upgrades could timeout during platform startup time.
• Added more performance improvements to the underlying parquet store service, to further improve the chart loading times for users. Parquet store service is only available on Dedicated Cloud, and Self-managed instances based on W&B kubernetes operator.
• Addressed the high CPU utilization issue for the underlying parquet store service, to make the efficient chart loading more reliable for users. Parquet store service is only available on Dedicated Cloud, and Self-managed instances based on W&B kubernetes operator.

1.7.2 - 0.60.0

Features

• Final updates for 1.1.1 Compliance of Level AA 2.2 for Web Content Accessibility Guidelines (WCAG) standards.
• W&B can now disable auto-version-upgrade for customer-managed instances using the W&B kubernetes operator. You can request this to your W&B team.
  • Note that W&B requires all instances to upgrade periodically to comply with the 6-month end-of-life period for each version. W&B does not support versions older than 6 months.

Fixes

• Fixed a bug to allow instance admins on Dedicated Cloud and Customer-managed instances to access workspaces in personal entities.
• SCIM Groups and Users GET endpoints now filter out service accounts from the responses. Only non service account users are now returned by those endpoints.
• Fixed a user management bug by removing the ability of team admins to simultaneously delete a user from the overall instance while deleting them from a team. Instance or Org admins are responsible to delete a user from the overall instance / organization.

Performance improvements

• Reduced the latency when adding a panel by up to 90% in workspaces with many metrics.
• Improved the reliability and performance of parquet exports to blob storage when runs are resumed often.
  • Runs export to blob storage in parquet format is available on Dedicated Cloud and on Customer-managed instances that are enabled using the W&B kubernetes operator.

1.7.3 - 0.58.1

Features

• W&B now supports sub-path for Secure storage connector i.e. Bring your own bucket capability. You can now provide a sub-path when configuring a bucket at the instance or team level. This is only available for new bucket configurations and not for existing configured buckets.
• W&B-managed storage on newer Dedicated Cloud instances in GCP & Azure will by default be encrypted with W&B managed cloud-native keys. This is already available on AWS instances. Each instance storage is encrypted with a key unique to the instance. Until now, all instances on GCP & Azure relied on default cloud provider-managed encryption keys.
• Makes the fields in the run config and summary copyable on click.
• If you’re using W&B kubernetes operator for a customer-managed instance, you can now optionally use a custom CA for the controller manager.
• We’ve modified the W&B kubernetes operator to run in a non-root context by default, aligning with OpenShift’s Security Context Constraints (SCCs). This change ensures smoother deployment of customer-managed instances on OpenShift by adhering to its security policies.

Fixes

• Fixed an issue where exporting panels from a workspace to a report now correctly respects the panel search regex.
• Fixed an issue where setting GORILLA_DISABLE_PERSONAL_ENTITY to true was not disabling users from creating projects and writing to existing projects in their personal entities.

Performance improvements

• We have significantly improved performance and stability for experiments with 100k+ logged points. If you’ve a customer-managed instance, this is available if the deployment is managed using the W&B kubernetes operator.
• Fixed issue where saving changes in large workspaces would be very slow or fail.
• Improved latency of opening workspace sections in large workspaces.

1.7.4 - 0.57.2

Features

You can now use JWTs (JSON Web Tokens) to access your W&B instance from the wandb SDK or CLI, using the identity federation capability. The feature is in preview. Refer to Identity federation and reach out to your W&B team for any questions.

The 0.57.2 release also includes these capabilities:

• New Add to reports drawer improvements for exporting Workspace panels into Reports.
• Artifacts metadata filtering in the artifact project browser.
• Pass in artifact metadata in webhook payload via ${artifact_metadata.KEY}.
• Added GPU memory usage panels to the RunSystemMetrics component, enhancing GPU metrics visualization for runs in the app frontend.
• Mobile users now enjoy a much smoother, more intuitive Workspace experience.
• If you’re using W&B Dedicated Cloud on GCP or Azure, you can now enable private connectivity for your instance, thus ensuring that all traffic from your AI workloads and optionally browser clients only transit the cloud provider private network. Refer to Private connectivity and reach out to your W&B team for any questions.
• Team-level service accounts are now shown separately in a new tab in the team settings view. The service accounts are not listed in the Members tab anymore. Also, the API key is now hidden and can only be copied by team admins.
• Dedicated Cloud is now available in GCP’s Seoul region.

Fixes

• Gaussian smoothing was extremely aggressive on many plots.
• Fixed issue where pressing the Ignore Outliers in Chart Scaling button currently has no effect in the UI workspace.
• Disallow inviting deactivated users to an organization.
• Fixed an issue where users added to an instance using SCIM API could not onbioard successfully.

Performance improvements

• Significantly improved performance when editing a panel’s settings and applying the changes.
• Improved the responsiveness of run visibility toggling in large workspaces.
• Improved chart hovering and brushing performance on plots in large workspaces.
• Reduced workspace memory usage and loading times in workspaces with many keys.

1.7.5 - 0.56.0

Features

The new Full Fidelity line plot in W&B Experiments enhances the visibility of training metrics by aggregating all data along the x-axis, displaying the minimum, maximum, and average values within each bucket, allowing users to easily spot outliers and zoom into high-fidelity details without downsampling loss. Learn more in our documentation.

The 0.56.0 release also includes these capabilities:

• You can now use cross-cloud storage buckets for team-level BYOB (secure storage connector) in Dedicated Cloud and Self-managed instances. For example, in a W&B instance on AWS, you can now configure Azure Blob Storage or Google Cloud Storage for team-level BYOB, and so on for each cross-cloud combination.
• In the same vein, you can now use S3-compatible storage buckets like MinIO for team-level BYOB (secure storage connector) in Dedicated Cloud and Self-managed instances. For example, in a W&B instance on GCP, you can configure a MinIO bucket hosted in cloud or on-prem for team-level BYOB.
• Admins can now automate full deletion of users in their Dedicated Cloud or Self-managed instances using the SCIM API’s DELETE User endpoint. The user deactivation operation has been reimplemented using the PATCH User endpoint, along with the introduction of user reactivation operation.
• If you use the SCIM API, you will also see a couple of minor improvements:
  • The API now has a more pertinent error message in case of authentication failures.
  • Relevant endpoints now return the full name of a user in the SCIM User object if it’s available.

Fixes

• The fix resolves an issue where deleting a search term from a runset in a report could delete the panel or cause the report to crash by ensuring proper handling of selected text during copy/paste operations.
• The fix addresses a problem with indenting bulleted items in reports, which was caused by an upgrade of slate and an additional check in the normalization process for elements.
• The fix resolves an issue where text could not be selected from a panel when the report was in edit mode.
• The fix addresses an issue where copy-pasting an entire panel grid in a Report using command-c was broken.
• The fix resolves an issue where report sharing with a magic link was broken when a team had the Hide this team from all non-members setting enabled.
• The fix introduces proper handling for restricted projects by allowing only explicitly invited users to access them, and implementing permissions based on project members and team roles.
• The fix allows instance admins to write to their own named workspaces, read other personal and shared workspaces, and write to shared views in private and public projects.
• The fix resolves an issue where the report would crash when trying to edit filters due to an out-of-bounds filter index caused by skipping non-individual filters while keeping the index count incremental.
• The fix addresses an issue where unselecting a runset caused media panels to crash in a report by ensuring only runs in enabled runsets are returned.
• The fix resolves an issue where the parameter importance panel crashes on initial load due to a violation of hooks error caused by a change in the order of hooks.
• The fix prevents chart data from being reloaded when scrolling down and then back up in small workspaces, enhancing performance and eliminating the feeling of slowness.

Learn more about how Saved views can enhance your team’s collaboration and project organization.

The release also includes these capabilities:

• You can now set a project’s visibility scope to Restricted if you want to collaborate on AI workflows related to sensitive or confidential data.
  • When you create a restricted project within a team, you can add specific members from the team. Unlike other project visibility scopes, all members of a team do not get implicit access to a restricted project.
• Enhanced Run Overview page performance: now 91% faster on load, with search functionality improved by 99.9%. Also enjoy RegEx search for Config and Summary data.
• New UX for Artifacts Lineage DAG introduces clustering for 5+ nodes at the same level, preview window to examine a node’s details, and a significant speedup in the graph’s loading time.
• The template variable values used for a run executed by launch, for example GPU type and quantity, are now shown on the queue’s list of runs. This makes it easier to see which runs are requesting which resources.
• Cloning a run with Launch now pre-selects the overrides, queue, and template variable values used by the cloned run.
• Instance admins will now see a Teams tab in the organization dashboard. It can be used to join a specific team when needed, whether it’s to monitor the team activity as per organizational guidelines or to help the team when team admins are not available.
• SCIM User API now returns the groups attribute as part of the GET endpoint, which includes the id of the groups / teams a user is part of.
• All Dedicated Cloud instances on GCP are now managed using the new W&B Kubernetes Operator. With that, the new Parquet Store service is also available.
  • Parquet store allows performant & cost efficient storage of run history data in parquet format in the blob storage. Dedicated Cloud instances on AWS & Azure are already managed using the operator and include the parquet store.
• Dedicated Cloud instances on AWS have been updated to use the latest version of the relational data storage, and the compute infrastructure has been upgraded to a newer generation with better performance.

Advanced Notice: We urge all customers who use Webhooks with Automations to add a valid A-record for their endpoints as we are going to disallow using IP address based Webhook URLs from the next release onwards. This is being done to protect against SSRF vulnerability and other related threat vectors.

Fixes

• You can now automate user role assignment for organization or team scopes using the SCIM role assignment API
• All Dedicated Cloud instances on AWS & Azure are now managed using the new W&B Kubernetes Operator. With that, the new Parquet Store service is also available. The service allows for performant & cost efficient storage of run history data in parquet format in the blob storage. That in turn leads to faster loading of relevant history data in charts & plots that are used to evaluate the runs.
• W&B Kubernetes Operator and along with that the Parquet Store service are now available for use in customer-managed instances. We encourage customers that already use Kubernetes to host W&B, to reach out to their W&B team on how they can use the operator. And we highly recommend others to migrate to Kubernetes in order to receive the latest performance improvements and new services in future via operator. We’re happy to assist with planning such a migration.

  • Refer to this blog on how you can run more important jobs than others using Launch.
• Refer to below changes for access control and user attribution behavior of team service accounts:
  • When a team is configured in the training environment, a service account from that team can be used to log runs in either of private or public projects within that team, and additionally attribute those runs to a user only if WANDB_USERNAME or WANDB_USER_EMAIL variable is configured in the environment and the user is part of that team.
  • When a team is not configured in the training environment and a service account is used, the runs would be logged to the named project within the service account’s team, and those would be attributed to a user only if WANDB_USERNAME or WANDB_USER_EMAIL variable is configured in the environment and the user is part of that team.
  • A team service account can not log runs in a private project in another team, but it can log runs to public projects in other teams.

Features

Prompts: Zoom and pan

Explore complex chains of LLM prompts more easily with new zoom and pan controls in our prompts tracer.

Model registry admin role

Control your model promotion process with a new role for model registry admins. These users can manage the list of protected aliases (for example, “challenger” or “prod”), as well as apply or remove protected aliases for model versions.

Viewer role

You can now share your W&B findings with a broader audience with the introduction of a Viewer role for W&B Server. Users with this role can view anything their team(s) make, but not create, edit, or delete anything. These seats are measured separately from traditional W&B Server seats, so reach out your W&B account team to request an updated license.

Improved sharing: optional magic link, and easier signup for viewers

Team admins can now disable magic link sharing for a team and its members. Disable public sharing on the team setting allows you increase team privacy controls. Meanwhile, it’s now easier for users who receive a report link to access the report in W&B after signing up.

Improved report composition

Reports help share your findings W&B further throughout an organization, including with people outside the ML team. We’ve made several investments to ensure it’s as simple and frictionless as possible to create and share them—including an improved report drafting experience with enhanced draft publication, editing, management, and sharing UX to improve how teams collaborate with Reports.

Updated navigation

As W&B has expanded the parts of the ML workflow we cover, we’ve heard your feedback that it can be hard to move around the application. So we’ve updated the navigation sidebar to include clearer labels on the product area, and added backlinks to certain detail screens. We’ve also renamed “Triggers” to “Automations” to better reflect the power of the feature.

Usage

wandb docker [OPTIONS] [DOCKER_RUN_ARGS]... [DOCKER_IMAGE]

Summary

Run your code in a docker container.

W&B docker lets you run your code in a docker image ensuring wandb is configured. It adds the WANDB_DOCKER and WANDB_API_KEY environment variables to your container and mounts the current directory in /app by default. You can pass additional args which will be added to docker run before the image name is declared, we’ll choose a default image for you if one isn’t passed:

images-public/tensorflow-1.12.0-notebook-cpu:v0.4.0 --jupyter wandb docker
wandb/deepo:keras-gpu --no-tty --cmd "python train.py --epochs=5" ```

By default, we override the entrypoint to check for the existence of wandb
and install it if not present.  If you pass the --jupyter flag we will
ensure jupyter is installed and start jupyter lab on port 8888.  If we
detect nvidia-docker on your system we will use the nvidia runtime.  If you
just want wandb to set environment variable to an existing docker run
command, see the wandb docker-run command.


**Options**

| **Option** | **Description** |
| :--- | :--- |
| `--nvidia / --no-nvidia` | Use the nvidia runtime, defaults to nvidia if   nvidia-docker is present |
| `--digest` | Output the image digest and exit |
| `--jupyter / --no-jupyter` | Run jupyter lab in the container |
| `--dir` | Which directory to mount the code in the container |
| `--no-dir` | Don't mount the current directory |
| `--shell` | The shell to start the container with |
| `--port` | The host port to bind jupyter on |
| `--cmd` | The command to run in the container |
| `--no-tty` | Run the command without a tty |

3 - JavaScript Library

Similar to our Python library, we offer a client to track experiments in JavaScript/TypeScript.

• Log metrics from your Node server and display them in interactive plots on W&B
• Debug LLM applications with interactive traces
• Debug LangChain.js usage

This library is compatible with Node and modern JS run times.

You can find the source code for the JavaScript client in the Github repository.

Installation

npm install @wandb/sdk
# or ...
yarn add @wandb/sdk

Usage

TypeScript/ESM:

import wandb from '@wandb/sdk'

async function track() {
    await wandb.init({config: {test: 1}});
    wandb.log({acc: 0.9, loss: 0.1});
    wandb.log({acc: 0.91, loss: 0.09});
    await wandb.finish();
}

await track()

Node/CommonJS:

const wandb = require('@wandb/sdk').default;

We’re currently missing a lot of the functionality found in our Python SDK, but basic logging functionality is available. We’ll be adding additional features like Tables soon.

Authentication and Settings

In node environments we look for process.env.WANDB_API_KEY and prompt for it’s input if we have a TTY. In non-node environments we look for sessionStorage.getItem("WANDB_API_KEY"). Additional settings can be found here.

Integrations

Our Python integrations are widely used by our community, and we hope to build out more JavaScript integrations to help LLM app builders leverage whatever tool they want.

If you have any requests for additional integrations, we’d love you to open an issue with details about the request.

LangChain.js

This library integrates with the popular library for building LLM applications, LangChain.js version >= 0.0.75.

import {WandbTracer} from '@wandb/sdk/integrations/langchain';

const wbTracer = await WandbTracer.init({project: 'langchain-test'});
// run your langchain workloads...
chain.call({input: "My prompt"}, wbTracer)
await WandbTracer.finish();

See this test for a more detailed example.

4 - Python Library

Use wandb to track machine learning work.

Train and fine-tune models, manage models from experimentation to production.

For guides and examples, see https://docs.wandb.ai.

For scripts and interactive notebooks, see https://github.com/wandb/examples.

For reference documentation, see https://docs.wandb.com/ref/python.

Classes

class Artifact: Flexible and lightweight building block for dataset and model versioning.

class Run: A unit of computation logged by wandb. Typically, this is an ML experiment.

Functions

agent(...): Start one or more sweep agents.

controller(...): Public sweep controller constructor.

finish(...): Finish a run and upload any remaining data.

init(...): Start a new run to track and log to W&B.

log(...): Upload run data.

login(...): Set up W&B login credentials.

save(...): Sync one or more files to W&B.

sweep(...): Initialize a hyperparameter sweep.

watch(...): Hooks into the given PyTorch model(s) to monitor gradients and the model’s computational graph.

4.1 - agent

Start one or more sweep agents.

agent(
    sweep_id: str,
    function: Optional[Callable] = None,
    entity: Optional[str] = None,
    project: Optional[str] = None,
    count: Optional[int] = None
) -> None

The sweep agent uses the sweep_id to know which sweep it is a part of, what function to execute, and (optionally) how many agents to run.

4.2 - Artifact

Flexible and lightweight building block for dataset and model versioning.

Artifact(
    name: str,
    type: str,
    description: (str | None) = None,
    metadata: (dict[str, Any] | None) = None,
    incremental: bool = (False),
    use_as: (str | None) = None
) -> None

Construct an empty W&B Artifact. Populate an artifacts contents with methods that begin with add. Once the artifact has all the desired files, you can call wandb.log_artifact() to log it.

Methods

add

View source

add(
    obj: WBValue,
    name: StrPath,
    overwrite: bool = (False)
) -> ArtifactManifestEntry

Add wandb.WBValue obj to the artifact.

add_dir

View source

add_dir(
    local_path: str,
    name: (str | None) = None,
    skip_cache: (bool | None) = (False),
    policy: (Literal['mutable', 'immutable'] | None) = "mutable"
) -> None

Add a local directory to the artifact.

add_file

View source

add_file(
    local_path: str,
    name: (str | None) = None,
    is_tmp: (bool | None) = (False),
    skip_cache: (bool | None) = (False),
    policy: (Literal['mutable', 'immutable'] | None) = "mutable",
    overwrite: bool = (False)
) -> ArtifactManifestEntry

Add a local file to the artifact.

add_reference

View source

add_reference(
    uri: (ArtifactManifestEntry | str),
    name: (StrPath | None) = None,
    checksum: bool = (True),
    max_objects: (int | None) = None
) -> Sequence[ArtifactManifestEntry]

Add a reference denoted by a URI to the artifact.

Unlike files or directories that you add to an artifact, references are not uploaded to W&B. For more information, see Track external files.

By default, the following schemes are supported:

• http(s): The size and digest of the file will be inferred by the Content-Length and the ETag response headers returned by the server.
• s3: The checksum and size are pulled from the object metadata. If bucket versioning is enabled, then the version ID is also tracked.
• gs: The checksum and size are pulled from the object metadata. If bucket versioning is enabled, then the version ID is also tracked.
• https, domain matching *.blob.core.windows.net (Azure): The checksum and size are be pulled from the blob metadata. If storage account versioning is enabled, then the version ID is also tracked.
• file: The checksum and size are pulled from the file system. This scheme is useful if you have an NFS share or other externally mounted volume containing files you wish to track but not necessarily upload.

For any other scheme, the digest is just a hash of the URI and the size is left blank.

checkout

View source

checkout(
    root: (str | None) = None
) -> str

Replace the specified root directory with the contents of the artifact.

WARNING: This will delete all files in root that are not included in the artifact.

delete

View source

delete(
    delete_aliases: bool = (False)
) -> None

Delete an artifact and its files.

If called on a linked artifact (i.e. a member of a portfolio collection): only the link is deleted, and the source artifact is unaffected.

download

View source

download(
    root: (StrPath | None) = None,
    allow_missing_references: bool = (False),
    skip_cache: (bool | None) = None,
    path_prefix: (StrPath | None) = None
) -> FilePathStr

Download the contents of the artifact to the specified root directory.

Existing files located within root are not modified. Explicitly delete root before you call download if you want the contents of root to exactly match the artifact.

file

View source

file(
    root: (str | None) = None
) -> StrPath

Download a single file artifact to the directory you specify with root.

files

    per_page: int = 50
) -> ArtifactFiles

Iterate over all files stored in this artifact.

finalize

View source

finalize() -> None

Finalize the artifact version.

You cannot modify an artifact version once it is finalized because the artifact is logged as a specific artifact version. Create a new artifact version to log more data to an artifact. An artifact is automatically finalized when you log the artifact with log_artifact.

get(
    name: str
) -> (WBValue | None)

Get the WBValue object located at the artifact relative name.

get_added_local_path_name

    timeout: (int | None) = None
) -> Artifact

If needed, wait for this artifact to finish logging.

__getitem__

__setitem__

View source

__setitem__(
    name: str,
    item: WBValue
) -> ArtifactManifestEntry

4.4 - Data Types

This module defines data types for logging rich, interactive visualizations to W&B.

Data types include common media types, like images, audio, and videos, flexible containers for information, like tables and HTML, and more.

For more on logging media, see our guide

For more on logging structured data for interactive dataset and model analysis, see our guide to W&B Tables.

All of these special data types are subclasses of WBValue. All the data types serialize to JSON, since that is what wandb uses to save the objects locally and upload them to the W&B server.

The Table class used to display and analyze tabular data.

Table(
    columns=None, data=None, rows=None, dataframe=None, dtype=None, optional=(True),

)

Unlike traditional spreadsheets, Tables support numerous types of data: scalar values, strings, numpy arrays, and most subclasses of wandb.data_types.Media. This means you can embed Images, Video, Audio, and other sorts of rich, annotated media directly in Tables, alongside other traditional scalar values.

This class is the primary class used to generate the Table Visualizer in the UI: https://docs.wandb.ai/guides/data-vis/tables.

Methods

View source

add_column(
    name, data, optional=(False)
)

Adds a column of data to the table.

add_computed_columns

add_computed_columns(
    fn
)

Adds one or more computed columns based on existing data.

add_data

View source

add_data(
    *data
)

Adds a new row of data to the table. The maximum amount of rows in a table is determined by wandb.Table.MAX_ARTIFACT_ROWS.

The length of the data should match the length of the table column.

add_row

View source

add_row(
    *row
)

Deprecated; use add_data instead.

cast

View source

cast(
    col_name, dtype, optional=(False)
)

Casts a column to a specific data type.

This can be one of the normal python classes, an internal W&B type, or an example object, like an instance of wandb.Image or wandb.Classes.

get_column

View source

get_column(
    name, convert_to=None
)

Retrieves a column from the table and optionally converts it to a NumPy object.

get_dataframe

set_fk(
    col_name, table, table_col
)

set_pk

4.5 - finish

Finish a run and upload any remaining data.

finish(
    exit_code: (int | None) = None,
    quiet: (bool | None) = None
) -> None

Marks the completion of a W&B run and ensures all data is synced to the server. The run’s final state is determined by its exit conditions and sync status.

Run States:

• Running: Active run that is logging data and/or sending heartbeats.
• Crashed: Run that stopped sending heartbeats unexpectedly.
• Finished: Run completed successfully (exit_code=0) with all data synced.
• Failed: Run completed with errors (exit_code!=0).
