Diogo Almeida launches Jev: 'a new type of frontier AI model'

TypeSafe AI founder Diogo Almeida, who describes himself as a ChatGPT co-inventor, announced Jev after two years in stealth, trained with a new method he calls RLCD. Claims: '20-200x faster', '40-400x cheaper (w/ output tokens free)', 'Frontier composable intelligence optimized for decisions', and 'the shortest path to AI-based economic revolution'. Speed and cost claims are the company's own.

After co-inventing ChatGPT, I kept asking myself: why have superhuman chat models not led to AGI?

I’ve spent the last 2 years in stealth building a new way to train models (RLCD), and a new type of frontier AI model that we are releasing today: Jev

• 20-200x faster • 40-400x cheaper (w/ output tokens free) • Frontier composable intelligence optimized for decisions

AFAICT the shortest path to AI-based economic revolution
