TypeSafe Jev Brings Sub-Second AI to Crypto and Stock Trading

TypeSafe AI launched Jev, a new class of artificial intelligence that makes real-time trading decisions at sub-second speed—roughly 40 to 200 times faster than conventional language models—with structured confidence scores rather than generated text. Jev, the company's inaugural System One model, debuted September 15, 2026, backed by $40 million in seed funding and founded by Diogo Almeida, who co-created Reinforcement Learning from Human Feedback (RLHF) at OpenAI.
