  "account": "On September 15, TypeSafe AI introduced Jev, an AI model that cannot produce text, code, or chat responses. Instead, it delivers structured decisions with calibrated probabilities for yes/no, multiple-choice, and scale score questions. The model, developed by former OpenAI researcher Diogo Almeida, is 20-200 times faster and 40-400 times cheaper than cutting-edge LLMs for decision-making tasks. With a pricing of $0.042 per million input tokens and free outputs, Jev quickly gained popularity among developers. Within hours of its release, users began utilizing Jev for tasks like real-time flight lookups and compressing large context windows. Jev's purpose lies in addressing a significant issue in agent systems: a substantial portion of LLM calls are not necessitating language generation. Researchers and practitioners are now breaking down intelligence into distinct components, such as System 2 reasoning (slow, generative thinking) and System 1 decision-making (fast, intuitive judgments). TypeSafe AI's Jev model exemplifies this transition, turning complex judgment calls into swift function invocations with near-zero costs, thereby driving demand for decision-making components.",
  "summary": "A Model That Can't Write Just Broke the Internet On September 15, TypeSafe AI released a model called Jev. The company was founded by former OpenAI researcher Diogo Almeida — a core author of RLHF and InstructGPT, the research that turned ChatGPT into ChatGPT. After two years in stealth and $40M led by DCVC, what they shipped was surprisingly restrained : Jev can't write a single word. No text…",
