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

The gains aren’t free: Jev can't generate text
Comparing Jev vs LLMs side-by-side makes the trade-off clear
Fun fact: replacing sequential computation with parallel is the same way Transformers leapfrogged RNNs

We believe that the future is code + AI, so made workflow evals to reflect that
Jev costs: $42 / BILLION input tokens ($0.042 / MTok) and output tokens are free (forever - they’re too cheap to meter with our new architecture)
Jev is named after Jevons paradox and off the intelligence per $ charts

We love how this doomo doomonstrates real-time intelligence and what can be doone with code + AI!

Game: race from one Wikipedia page to another using only links
Challenge: choosing between hundreds to thousands of links
Shows not just intelligence-per-second, but also the compounding benefits of not hallucinating with high-cardinality choices

Extraordinary claims require extraordinary evidence so check out our release blog for more technical info: typesafe.ai/blog/introduci…
Join our waitlist for early access: typesafe.ai
Have technical chats and meme with us on Discord (rumors are good memers skip the line): discord.gg/WUujKYBp8s
We are so pumped this is in the hands of developers now, and we are just getting started!!!
