elvis(@omarsar0):NEW: Microsoft also releases its System One model, Microsoft-Decision-1. What a crazy effect Jev has had in the space. Also, a very cool application of decision-making models to power LLM judges and improve scientific discovery pipelines (e.g., screening candidate hypotheses). I'll add this model to my ever-growing list of eval runs. In my ongoing evals, consistency and more complex decision-making are two areas where I see these decision models struggle. I'm also exploring a bunch of science applications at @dair

Introducing Microsoft-Decision-1, our new model for fast decision-making. It delivers top performance on structured decision tasks, outperforming both LLMs and other decision models in latency and quality. We’re already testing it across Microsoft for everything from incident response and quality control to scientific discovery.
