Microsoft CEO Satya Nadella announced Microsoft-Decision-1, a small model purpose-built for fast structured decisions: routing, classification, agent controls, and AI judging, returning calibrated probabilities per option.
Key specs (via third-party recap):
- Post-trained from Qwen3.5-9B
- 35x faster than GPT-6 Sol, 4.5x faster than the runner-up
- Top accuracy across 36 benchmarks
- $0.042 per million input tokens, output free
Nadella says Microsoft is already testing it internally for incident response, quality control, and scientific discovery.
