TypeSafe AI Launches Jev, a Decision Model That Broke AI Gateway Records on Day One

TypeSafe AI, the startup founded by ChatGPT co-creator Diogo Almeida, released Jev on September 15 as a probabilistic decision engine for software—and demand was so intense the system briefly lost API serving capacity, marking an unusual moment for a newly launched AI model. Jev is not a language model. Instead of generating prose, it returns typed decisions: picking one option from a list (Choice), rating something on a scale (Score), or estimating the probability a statement is true (Noul). The model runs in 70 to 500 milliseconds and costs $0.042 per million input tokens; output tokens are free. TypeSafe emerged from two years of stealth with $40 million in seed funding led by DCVC.
