TypeSafe AI, founded by InstructGPT co-author Diogo Almeida, shipped Jev on Sept 15, 2026 — a model that refuses to chat. It takes program state plus typed questions and returns choices, scores, and yes/no probabilities in 70-500ms, priced at $0.042/M input tokens with free output. Within two days builders used it to play Doom, book flights in 7 seconds, compact agent memory without summarization, and fire trades per blockchain block. The author's operator framing: using frontier models for clerical decisions is a donation of latency, margin, and control.
