DeepSeek V4 Pro and V4 Flash are now available as Azure providers in Vercel's AI Gateway, enabling automatic failover and provider preference routing with no code changes required.
June 15, 2026
Summary
Developers get an additional failover path for DeepSeek inference without modifying existing code. Using `order` in gateway provider options lets teams prefer Azure while maintaining fallback to other providers, reducing latency variance and improving reliability for production deployments.
Why it matters

Implementation verdict
Replaces manual provider fallback logic. Requires only optional configuration changes via `providerOptions.gateway.order` if you want to prioritize Azure; existing code works unchanged. Worth trying now if you need multi-region redundancy for DeepSeek without vendor lock-in.
