TypeSafe AI unveils Jev model as cheaper alternative to ChatGPT

Jev: Jev is TypeSafe AI's first System One model, released in early access on September 15, 2026, and designed to return typed decisions such as choices, scores, or probabilities from supplied state data and predefined questions. It uses a parallel sampler and specialized training approach to deliver schema-guaranteed outputs without any text generation or risk of hallucinations. The model is hosted via API and SDKs, with access currently managed through a waitlist for developers integrating it into automation pipelines. TypeSafe AI: TypeSafe AI is a San Francisco-based artificial intelligence company founded in 2024 that focuses on developing models for machine-consumed intelligence rather than human-facing text generation. It emphasizes new architectures and training methods optimized for structured, verifiable outputs that software can act on directly. The company recently emerged from stealth to release its first public model, positioning the offering for automation workflows traditionally addressed by large language models. Product: Jev processes queries in a single parallel pass and returns only structured values, enabling direct code integration without additional parsing or validation steps. Adoption: Early access to Jev is available through TypeSafe's API and official SDKs, with developers using it for classification, routing, scoring, and verification tasks in applications. Innovation: TypeSafe AI coined the term System One models, drawing from psychological concepts of fast intuitive judgment to create AI optimized for software rather than chat interfaces.
