Launch thread by Diogo Almeida
TypeSafe's founder on why RLCD-trained decision models are a shorter path to value than chat models.
Open x.com ↗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

How builders describe it
Diogo Almeida's launch thread: after co-inventing ChatGPT, he spent two years on RLCD and Jev, a System One model he pitches as 20-200x faster and 40-400x cheaper for typed decisions.
