October 10, 2026Microsoft-Decision-1 in Foundry: $0.042 and the EU zone
Microsoft-Decision-1 went GA in Microsoft Foundry on 9 October 2026 at $0.042 per million input tokens with free output, returning calibrated probabilities over fixed options instead of text, and it launched with an EU Data Zone at the same price as the US zone. We compare it with OpenAI's Decisions API and H2O-Lightning-4B, run the cost math for ticket routing and agent step-gating, and set out what Swedish buyers must record about its Qwen3.5-9B base.
