[260924] Jev, Laya Go Viral: New Class of AI Models Sweeps Silicon Valley

TypeSafe AI released Jev, a decision-only AI model that outputs direct choices, scores, or probabilities instead of generated text, with latency in the tens to hundreds of milliseconds and input costs of $0.042 per million tokens. A similar open-source model, Laya, is available on Hugging Face. The models target use cases including games such as Snake, 2048, Tetris, Minecraft, and racing/FPS titles, software tasks like email tagging and search re-ranking, and agent functions such as routing, tool selection, and next-step logic, following a fixed context → AI decision → code action workflow.
