Microsoft-Decision-1 is live on OpenRouter.
Microsoft's numbers: highest accuracy across 36 blind benchmarks (~150K questions), 4.5x faster than the runner-up, 35x faster than GPT-6 Sol, and decisions flip on just 1.3% of perturbed inputs. Post-trained from Qwen3.5-9B.

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.
We’re already testing it across Microsoft for everything from incident response and quality control to scientific discovery.

Claude Fable 5.1, the latest in @AnthropicAI's Mythos model class, is now generally available in GitHub Copilot.
In our testing it showed strong performance on
➡️ long-running coding tasks
➡️ deep codebase research
➡️ complex agentic workflows
Try it out in the GitHub Copilot app, CLI or @code.

📣 @OpenAIDevs has reduced the price for GPT-5.6 Sol by 50% until September 3.
Try it out in GitHub Copilot wherever you work.
📣 @OpenAIDevs's GPT-5.6 family is now generally available and rolling out in GitHub Copilot.
GPT-5.6 comes in three variants:
☀️ GPT-5.6 Sol: the highest reasoning ceiling in the family. Best for complex reasoning over large codebases and demanding, long-running agentic work.
🌎 GPT-5.6 Terra: the balanced default. A strong all-round choice for everyday interactive and agentic coding.
🌕 GPT-5.6 Luna: a lightweight, cost-efficient variant for smaller, faster tasks and the lowest-cost option in the family.
Try one, two, or them all in @code or the GitHub Copilot app.

Agent on the left. Real browser on the right. Same terminal.
terminal-browser + GitHub Copilot CLI = zero context switching while building.

Your agent worked, it shipped… but it leaked your data.
In this #AzureFriday, @shanselman and Sajeetharan Sinnathurai show how Agent Kit helps catch missing partition key filters, fix fan-out queries, and prevent cross-tenant data leaks.
