ChatGPT co-inventor launches Jev, a decision-only AI model claiming 200x speed and 400x cost savings
TianbaoX · x · 2026-09-16
Diogo Almeida, who co-invented ChatGPT, has come out of two years of stealth to launch Jev, trained with his new method RLCD and positioned as a frontier model optimized for decisions rather than text generation.
Key claims:
- 20–200x faster and 40–400x cheaper than comparable LLMs
- $0.042 per million input tokens, with output tokens free
- The trade-off: it cannot generate text at all
Demos include controlling a game and choosing Wikipedia links. Almeida frames embedding fast, cheap AI decisions into software as "the shortest path to an AI-based economic revolution," though observers note the claims sound almost too good to be true.
