Microsoft launched Microsoft-Decision-1, a model for fast decision scoring that returns calibrated probabilities for fixed options via a structured API. It is available in Microsoft Foundry and will be on OpenRouter soon. The model achieved the highest accuracy in a 36-benchmark evaluation and is 4.5 times faster than Quyet-1.0-Large and 35 times faster than GPT-6 Sol at P50 latency. Pricing starts at $0.042 per million input tokens with free output tokens.

## Evidence

Verbatim from https://www.testingcatalog.com/microsoft-launches-decision-1-model-in-foundry/:

> Rather than generating open-ended text, Microsoft-Decision-1 takes a fixed set of options and returns a calibrated probability for each through a structured API call.
