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 Show more

Highlights
- The video announcement from TypeSafe cofounder Diogo Almeida.
- Frames Jev as the output of two years building RLCD, a training method placed beside RLHF and RLVR.
- Headline claims: 20-200x faster and 40-400x cheaper than chat models for the decisions it replaces.
Watch out
The speed and cost multiples are vendor launch claims; reproduce them on your own workload before quoting them.

A really smart switch statement
hype-free explanation of jev: jev does not replace gpt / claude jev is just a *really* smart switch statement like if 2016 ml classifiers got 2026 levels of intelligence it's a new* type of tool that will make a lot of workloads insanely fast, cheap, and accurate * = and by Show more
