grok ai-gateway multimodal routing inference

Grok 4.6 arrives on Vercel AI Gateway

500K context window, multimodal reasoning model now routable through unified AI Gateway with cost tracking and failover support.

Summary

Developers can swap reasoning models without API refactoring, and get provider pricing transparency plus failover/retry automation in a single integration point. Reduces operational overhead for multi-model inference patterns.

Why it matters

Implementation verdict

Replaces direct xAI API calls for teams already on Vercel. Requires only model string swap in AI SDK (`xai/grok-4.6`) plus optional reasoning level config. Worth evaluating now if you need reasoning tiers or unified cost tracking; low friction adoption.
