Configure where run state lives in Vercel Workflows

Short summary

Vercel Workflows now pins each run's state, queue dispatch, and output streams to a single home region — either where the run starts or a region you explicitly choose. This keeps AI agent execution loops close to end users, with automatic failover to the nearest region during incidents. Existing workflows adopt regional placement automatically on their next run after updating to Workflow SDK 5.0.0-beta.33 or later.

• •Run state, queue dispatch, and output streams now stay in a single home region for each workflow run's lifetime
• •Pin runs to a specific region via the region option in start(); existing workflows need no migration
• •Requires Workflow SDK [email protected] or later; traffic fails over to nearest region during incidents
