A new category of AI models, termed 'Decision AI models', has emerged, designed to return structured decisions rather than free-form text. TypeSafe AI pioneered this with its Jev model, which accepts typed questions and returns choices, scores, or probabilities that can be directly processed by code. This approach aims for calibrated probabilities and faster, cheaper responses compared to traditional LLMs. Competitors like Fastino Labs have already released similar models, and open-source reproductions are appearing, indicating rapid adoption and development in this specialized AI field.
