Vercel adds session affinity view to AI Gateway logs
Vercel’s AI Gateway now includes a Sessions view that groups requests into sessions and displays routing details. Each entry lists the coding agent or app (e.g., Claude Code, Codex, Cursor), associated costs, models, providers, cache hit rate, duration, and turn-by-turn timing. The view also shows how much input was cached across each turn and the provider serving the session.
Why it matters: Understanding session routing and cache performance helps developers optimize AI‑driven workflows and control costs.
