Diogo Almeida is the CEO of TypeSafe AI, the San Francisco lab that came out of stealth with this post on 15 September, and before that a researcher at OpenAI on the instruction-following work that led to ChatGPT. Jev is the lab's first model and it is not a chatbot: you hand it the state of a program plus typed questions, and it answers every question at once as a decision with a calibrated probability, in 70 to 500 milliseconds, with no text generated at all. TypeSafe prices it at $0.042 per million input tokens with output free, and its own evals put it up to 193.6x faster and 444.6x cheaper than GPT-6 Astra and Fable 5.1 on four workflows the lab wrote itself, a caveat the launch post lists. The company raised a $40 million seed led by DCVC. The film is the launch video, and the second post in the thread is Jev playing Doom. Nearly everything else on this page was made in the four days after.

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
Andre Landgraf's showcase of the yes/no gate, several worked examples at the link.

Ok, jev is really cool. So many great use cases where a fast and accurate yes/no gate can deliver meaningful performance gains.
Played around and built some showcase examples here →
Vipul Sharma's Minecraft agents ask Jev whether to fight or run, from what the agent can see, the mob count, its weapon and its health; one broke off mid-fight as the odds turned.

I hooked up Jev by @typesafeai to a few agents on my Minecraft world. Look at how Jev decides when they should fight and when they should run away.
Jev rates the odds from what the agent can see, mob count, weapon, how hurt it is, and runs away when they are bad. One broke off mid-fight as its odds turned.
Mahmoud's simulation of fifteen autonomous drones through an asteroid field, Jev deciding for each in under 300 ms, all fifteen arriving.

Jev can control a swarm of 15 autonomous drones in real time!
I built a simulation to test it navigating an asteroid field:
• Decision latency: < 300ms
• Survival rate: 100% (all 15 reached the destination)
