Microsoft Decision 1
Microsoft's small decision model, which reads the content it is given and returns a calibrated probability for each fixed answer option instead of writing text.
Decision 1 is a cloud decision model from Microsoft. It reads a piece of text and answers typed questions about it, such as a choice between labels, a yes or no, or a score on a scale, with a probability for every option instead of written text. It reads up to 33K input tokens per request. It runs through OpenRouter using your own API key, from $0.042 per million input tokens.

Samples
Answered by Decision 1 via OpenRouter. A decision model returns probabilities, not prose, so each card shows how sure it was about every option. The same four questions run against every Decision model in the catalog.
