Ex-OpenAI team launches Jev, a non-LLM model that outputs typed values with confidence scores, raises $40M
cephaloform · x · 2026-09-24
- TypeSafe AI released Jev, a proprietary model backed by a $40M seed round led by DCVC.
- Unlike an LLM, Jev doesn't generate natural language text — it returns typed values with probability estimates and confidence scores, meant to be consumed directly by other software.
- The company calls it the first of a class of "System One models", named after Kahneman's fast, intuitive thinking, positioned as a fix for overconfidence in human-pleasing conversational models.
- CEO Diogo Almeida spent 4 years at OpenAI on RLHF, InstructGPT, ChatGPT and GPT-4.
