Designing a Reliable Async AI Video Pipeline in TypeScript

Short summary

A reference architecture for reliable async AI video generation pipelines in TypeScript, addressing the gap between demo simplicity and production complexity. Key patterns include a provider-neutral state machine, persisting local task IDs before calling providers, server-side model capability validation, and pre-billing input moderation. The architecture separates internal task identity from external provider IDs, enabling clean provider swaps and consistent billing/authorization across the generation lifecycle.

• •Provider-neutral state machine normalizes provider-specific statuses into running/processing/completed/failed
• •Persist local task before calling provider—separate internal IDs from external provider IDs
• •Server-side capability validation and pre-billing moderation protect costs and enforce policy

Generated with AI, which can make mistakes.
