    Guillermo Rauch is the CEO of Vercel. fx is Vercel's coding agent, its default mode is auto, and every command it runs is checked first by a safety reviewer. That reviewer runs on GPT Luna; the Vercel team benchmarked Jev in its place and found it up to 18x faster at p95 and more accurate, which Rauch says makes it the likely new default. The first production guardrail anyone named this week.

    We're seeing extraordinary results from @typesafeai. Default mode in 𝚏𝚡 is auto, with a safety reviewer analyzing every command.

    That reviewer runs on GPT Luna today. Jev is up to 18x faster (p95) *and* more accurate. It's coming to @vercel AI Gateway and likely new default.
