Microsoft introduced a new artificial intelligence model on Friday. The company calls it Microsoft-Decision-1. It is built to make fast decisions rather than write long answers.

Introducing Microsoft-Decision-1, our new model for fast decision-making.

It delivers top performance on structured decision tasks, outperforming both LLMs and other decision models in latency and quality.

The company says the model works 35 times faster than OpenAI’s GPT-6 Sol. It also ran 4.5 times faster than a rival model called Quyet-1.0-Large during Microsoft’s own tests.

Microsoft-Decision-1 is not a typical chatbot. It does not generate detailed written responses. Instead, it picks between a set of fixed options, such as yes or no, multiple choice, or a rating scale.

How Companies Could Use the Model

Businesses could use the tool to sort customer support tickets. It could also decide which technical problems need attention first.

The model can check whether another AI system’s answer meets certain quality standards. This process is sometimes called AI judging.

Microsoft said simple tasks like these matter more as AI systems take on longer jobs. Each decision adds time, so a faster model can speed up the whole process.

The company ran tests across 36 benchmarks. These benchmarks covered close to 150,000 questions. Microsoft says the model scored the highest accuracy among all options tested.

Pricing is set at $0.042 per million input tokens. There is no charge for output tokens. Microsoft says this adds up to savings of up to 200 times lower cost in some internal tests.

Microsoft Is Testing the Tool Across Its Own Products

Microsoft CEO Satya Nadella said the company is already using the technology inside its own teams. One use case is technical incident response. Another is quality control for AI answers.

The Xbox research team used the model to review more than 10,000 customer comments. These came from surveys, Steam, and social media posts.

Microsoft said the results matched GPT-6 Sol in quality. But the model ran over 14 times faster. It also cost about 200 times less to run.

The Copilot team also tested the system. They used it to check AI-generated responses for quality. Microsoft said the model delivered similar results at close to 100 times the speed of another advanced AI model.

Developers can access Microsoft-Decision-1 through Microsoft Foundry. The company also plans to make it available through OpenRouter, a platform that connects developers to different AI models.

What Analysts Say About the Stock

Wall Street analysts currently rate Microsoft stock as a Strong Buy. This is based on 36 Buy ratings and one Hold rating over the past three months.

The average price target for Microsoft stock sits at $586.14 per share. That reflects about 9.3% upside from current levels.

Microsoft has not said when it plans to expand testing of Decision-1 beyond its internal teams. The company said it will keep releasing updates to improve the model’s speed and accuracy over time.
