3/ Jev is the model everyone was playing with. TypeSafe came out of stealth Monday. Diogo Almeida, who says he co-invented ChatGPT, spent two years on a different way to train models. - No text generation. You hand it state and typed questions, it returns answers from your schema - 70 to 500 ms end to end - $0.042 per million input tokens, output free - Early access, waitlist The demos were Mario, real-time game levels, colour picking. The part I care about is a model that can't return anything outside the schema. Nothing to parse, nothing to validate.
