TypeSafe AI has introduced its first model named Jev - a small and customizable System One decision model. Not being an LLM, Jev can’t reason or write explanations; it generates a fast judgment with calibrated probabilities and a confidence score. Anything heavier gets split into separate questions and recombined in code. TypeSafe reports a response time of approximately 150ms per call, at around 100x lower cost and faster responses than LLMs, with pricing at $42 per billion input tokens and free output.
