Microsoft-Decision-1 is the decision model in Microsoft Foundry and on OpenRouter. It scores a fixed set of options instead of writing text. Input $0.042 per million tokens. Output free. No setup fee.
Most application logic doesn't need a generated response. It needs a confident answer from a fixed set of options. Decision models return probabilities per option in a single pass, at a tiny fraction of the cost of an LLM call.
Response shape: one probability per option per question. Use your own floor.
Microsoft-Decision-1 is on Fikra's pilot roadmap. Ask on [email protected] to be on the first batch.
Yes. Paid accounts can call it. Pilot accounts as well. Ask on [email protected].
Post-trained Qwen3.5-9B, Apache 2.0. Microsoft plans to rebase it onto OpenAI and MAI models later.
32K tokens. Decisions should fire on short inputs; for very long inputs either chunk the input or use a chat model to extract first.
