SITUATION EXPLAINED: "Models have been superhuman at chat for years, so where is all the automation?" • Diogo Almeida spent years at OpenAI on the instruction-following work behind ChatGPT, then two years in stealth building an answer • His model, Jev, takes unstructured state and returns typed decisions with calibrated probabilities, in one parallel pass rather than token by token • It cannot generate text at all • They call it a System One Model, after Kahneman's fast intuitive thinking • It runs 20 to 200x faster and 40 to 400x cheaper than an LLM, at $0.042 per million input tokens with output free • $40 million seed led by DCVC. No independent evaluations at launch @sophiadew: "Maybe we don't need another general purpose model to just talk and talk and talk. We just need something that's really good at not hallucinating and making better decisions."
