Microsoft launches Decision-1, a 9B parameter model for rapid decision scoring
Key points
- Microsoft launched Decision-1, a 9B parameter model.
- It scores predefined answer options with probabilities.
- Built on Alibaba's Qwen3.5-9B model.
- Available via Microsoft Foundry and OpenRouter.
Microsoft Introduces Decision-1 Model
Microsoft announced the release of Decision-1, a new AI model. Unlike generative AI models, Decision-1 does not produce text, summaries, or emails. Instead, it evaluates a fixed list of answer options in a single pass, providing a probability score for each option.
Technical Foundation and Availability
Decision-1 is built upon Alibaba’s Qwen3.5-9B model. Microsoft made it immediately available through Microsoft Foundry, with subsequent availability on OpenRouter. The company has indicated internal applications for the model, including incident response and scientific discovery.
Specialized Functionality for Specific Tasks
While many AI models focus on generating extensive content, Decision-1 is designed for narrow, high-volume, low-latency decision-making. Its core functions include routing, classification, prioritization, verification, and workflow control. Examples include directing support tickets, moderating user content, or validating AI agent outputs.
Impact on AI Development
This specialized approach offers an alternative to general-purpose chatbots for engineering teams developing agent pipelines and automated verification systems. Decision-1 provides a direct probability distribution over predefined options, simplifying the process compared to parsing and interpreting open-ended generative model outputs.
