Jev’s creator, Diogo Almeida, announced its release on September 15, 2026, saying he spent two years in stealth developing the model and a training method called RLCD. He claims Jev is 20–200x faster and 40–400x cheaper, with free output tokens. Posts discussing Jev describe it as answering structured questions in parallel and returning choices or scores with probabilities and confidence instead of free-form text. One commenter suggests using that confidence to decide when human review is needed, while urging readers to wait for benchmarks. Investor DCVC says TypeSafe emerged from stealth with Jev backed by a $40 million seed round it led.
