Ex-OpenAI researcher Diogo Almeida builds Jev, a 'System 1' AI model that skips language
A Fireship video covers Jev, a 'System 1' AI model built in stealth over two years by ex-OpenAI researcher Diogo Almeida. The model cannot talk or write code but is claimed to run 200x faster and 400x cheaper than LLMs while being hallucination-free. Its launch challenges the assumption that language is necessary for AI reasoning.

Jev: System One models for Prod, not God — with Diogo Almeida, CEO, TypeSafe AI
During Jev launch week, Latent Space published an interview with Diogo Almeida, CEO of TypeSafe AI and InstructGPT co-author, on why he built a 'System One' model for production software rather than chat. Jev's launch video drew ~40M views, and its core training technique, Reinforcement Learning for Calibrated Decisions (RLCD), optimizes for calibrated probabilities instead of human preference feedback. Practitioners get official patterns, cookbooks, and a coding-agents guide, plus use cases spanning computer use, games, linting, and analytics.

Developer builds independent benchmark for AI "decision models" like Clef and Decisions API, publishing all 100 test cases and answers
A developer released decisionmodelhub.com, an independent benchmark measuring AI 'decision models' — purpose-built models that pick answers from fixed lists — on the same 100 support-ticket routing tasks. Vendors tested include Jev, Cloudflare's Clef, and OpenAI's Decisions API. Purpose-built models run 5 to 12 times faster than a general LLM, which gets slightly more tickets right.
