TypeSafe Launches Jev, a Probabilistic Decision Model That Outpaces Text-Generating AI by 200x

TypeSafe AI, founded by ChatGPT co-creator Diogo Almeida, released Jev on September 15, 2026, a fundamentally new class of foundation model designed to make rapid structured decisions rather than generate text. Unlike large language models that produce output token by token, Jev takes unstructured program state as input and returns typed decisions—a selection from a fixed set of options, a numeric score, or a yes/no probability—in a single parallel pass. The output includes confidence scores derived from the model's internal probability distribution, enabling developers to route low-confidence decisions to human review.
