AI Gateway launches unified fast mode for lower latency
Vercel's AI Gateway introduces a beta unified fast mode, allowing developers to request faster inference for any supported model with a single speed parameter. Fast mode trades higher per-token cost for reduced latency or increased throughput, falling back to standard speed when unavailable. The feature works across all API formats and includes direct fast slug support for model fallback lists.

Useful for latency-sensitive apps, but the higher cost and limited model availability mean it's a niche optimization, not a universal upgrade.
