🖥 Microsoft Releases Decision-1

Decision-1 does not generate text. It takes a task with several answer options and returns a probability for each in one pass. It is built on Qwen3.5-9B. Microsoft says it is 35 times faster than GPT-6 Sol in internal tests.

The model can help AI agents choose whether to continue a task or hand control to a person. It achieved the highest accuracy across 36 benchmarks, covering nearly 150,000 questions.

Xbox used Decision-1 to classify more than 10,000 player reviews. Processing was 14 times faster than GPT-6 Sol and 200 times cheaper. Input costs $0.042 per million tokens, with free output tokens. It is available through Microsoft Foundry and will later appear on OpenRouter.
