Diogo Almeida, a former OpenAI researcher who helped build ChatGPT and co-invent reinforcement learning from human feedback (RLHF), has launched a new AI model that abandons natural language output entirely. This week, his startup TypeSafe AI released Jev, a transformer-based model that produces only probabilities — or what the company calls 'calibrated decisions' — rather than text, making it cheaper, faster, and unable to hallucinate. Developers have already shown intense interest, with the company briefly losing the ability to serve users from its API due to demand.
Why it leads A non-language AI model from a ChatGPT co-inventor signals a potential shift in the field's trajectory, with a fresh technical approach that commands attention. |
