ChatGPT co-inventor launches Jev: up to 200x faster, 400x cheaper decision-optimized model

Diogo Almeida, who says he co-invented ChatGPT, unveils Jev, a new frontier model trained with RLCD, a method he developed over two years in stealth. Jev targets composable intelligence optimized for decisions rather than free-form generation: claimed 20-200x faster, 40-400x cheaper with free output tokens. He frames it as the shortest path to an AI-based economic revolution.
