W&B Automation Jobs

Automated CI/CD workflows triggered by W&B Automations. When a model is promoted in the W&B Registry (e.g., the production alias is added), a webhook fires and triggers a GitHub Actions workflow that creates a review issue.

How it works

1. A model artifact is promoted in the W&B Model Registry (alias production is added)
2. W&B fires a webhook automation with artifact metadata (version, collection, author, project)
3. The webhook triggers a GitHub Actions repository_dispatch event
4. The GitHub Action creates a review issue from a template, populated with the promotion details

Setup

Prerequisites

• A W&B account with access to Automations (Pro or Enterprise plan)
• A GitHub Personal Access Token (PAT) with repo scope or fine-grained permissions for Issues (read/write) and Contents (read)

GitHub repo configuration

1. Add a repository secret called ACTION_PAT with your GitHub PAT value (Settings -> Secrets and variables -> Actions)

W&B configuration

1. Create a Secret in W&B Team Settings: name it GITHUB_TOKEN, paste your GitHub PAT
2. Create a Webhook in W&B Team Settings:
   • Name: github-model-cicd
   • Endpoint: https://api.github.com/repos/<OWNER>/<REPO>/dispatches
   • Access token: select the GITHUB_TOKEN secret
3. Create an Automation on the Registry or Project:
   • Event: "An artifact alias is added"
   • Alias regex: ^production$
   • Action: Webhook -> github-model-cicd
   • Payload:

     {
       "event_type": "webhook",
       "client_payload": {
         "event_author": "${event_author}",
         "artifact_version": "${artifact_version}",
         "artifact_version_string": "${artifact_version_string}",
         "artifact_collection_name": "${artifact_collection_name}",
         "project_name": "${project_name}",
         "entity_name": "${entity_name}"
       }
     }

Test it

1. In W&B Team Settings, find your webhook and click the ... menu -> Test
2. Paste the payload above (replace ${} variables with sample values) and click "Test webhook"
3. Check the GitHub Actions tab — a workflow should run and create an issue

Files

.github/
  PROMOTION_TEMPLATE.md          # Issue template with artifact metadata
  workflows/
    model_promotion_ci_cd.yml    # GitHub Actions workflow triggered by webhook

Extending this pattern

This example creates a GitHub Issue for human review. In production, the same pattern can trigger:

• Model evaluation on a held-out benchmark
• Deployment to a serving endpoint (SageMaker, Vertex AI, etc.)
• Slack/Teams notifications to the ML platform team
• A PR that updates a model config file in a deployment repo

The webhook payload passes all the artifact metadata needed to identify and fetch the model programmatically via the W&B Public API.
