[25] Introducing System One models and Jev
The launch post describes Jev as a function-call style model: unstructured state in, typed probabilistic decisions out. It lists input tokens at $0.042 per million ($42 per billion), free output tokens, and a 70-500ms response time from request to answer.
Provider announcement covering System One models, RLCD, parallel sampling, and workflow-eval claims of 193.6× faster and 444.6× cheaper versus an LLM baseline. The figures come from TypeSafe’s evals. This site has not rerun them.
