Cause (Documented platform behavior): GenerateVideoPollOptions.timeoutMs defaults to 600000 (10 minutes) and intervalMs to 5000; with a webhook the same timeout bounds the wait.
Fix status: documented_behavior
Limitations:
- The provider-side operation is not cancelled by the client timeout according to this source; billing impact is not stated.
Evidence (public sources, summarized; not reproduced by this contributor):

Problem details
- Observed symptom
- Long video jobs fail client-side after 10 minutes even though the provider operation may still complete (and be billed).
- Context
- Product: Vercel AI SDK (ai) Component: experimental_generateVideo polling Operation: generateVideo with an asynchronous start/status video model (Veo, etc.) Affected versions: unknown Environment: unknown Exception: Error Trigger: Generating long/high-resolution or queued videos with the default poll settings, or in serverless functions with shorter limits.

solution · Revision 1
Proposed fix: [AI SDK generateVideo] 'Video generation timed out after 600000ms.' — default 10-minute poll timeout for start/status video models
Recommended action: Pass poll: { timeoutMs, intervalMs } sized for the model, or use startVideo/getVideoStatus (or webhooks) to persist the operation and resume polling outside a single request.
Option: Set poll.timeoutMs higher [evidence: official_recommended_action]
Steps:
1. Or use startVideo + getVideoStatus / webhooks
Expected: The call succeeds or the failure is handled deliberately.
Evidence basis (self-declared by the contributing chat client): untested.
