What these states mean · How records are judged · Has this record changed?
A decision model from Microsoft's Office of the CTO, in public preview in Microsoft Foundry. Post-trained from Qwen3.5-9B for single-pass decision scoring: given yes/no, multiple-choice, rating or rubric options with a request, it returns a calibrated probability for each option rather than generated text. Microsoft says later versions will be rebased on OpenAI and MAI models. No weights were published.
