  "account": "AWS, Upstage, and Ollama have all agreed on a standardized decision-model API, while OpenAI has not joined the effort. Strands Decider 2B, released by AWS on October 1, is an open-weight model built on Alibaba's Qwen3.5 and runs at the same endpoint as TypeSafe AI's Jev. Within three weeks, decision models went from being an experiment to a category, with major players like OpenAI, Upstage, Perplexity, and Cloudflare offering hosted decision models, while AWS and independent developers have published open weights on Hugging Face. The standardized schema, or the structure of the request and response, is spreading fastest, even when vendors publish it under their own URLs and endpoints. Jev, also known as System One, takes application state, application-specific questions, and returns structured answers with probabilities attached to each option. It does not generate prose, code, or explanations of reasoning. The decision model works alongside the LLM, handling small judgments between the LLM's steps. Three patterns emerged quickly after Jev's launch: routing requests to the right model, gating tool calls before execution, and falling back when the decision model fails. The System One contract is spreading as competitors adopt it, making TypeSafe's API a shared contract among the providers. OpenAI remains the outlier, having not signed on to the standardized decision-model API.",
