# AI Round-up: 26 September 2026

## Summary

Microsoft expanded Copilot's code-execution and agent capabilities, with first-party detail on its Managed Runtime and video coverage of the wider update. OpenAI faced further scrutiny as reporting examined the scope of agent activity and access to US government data.

Anthropic published Claude's calculation of a nine-loop amplitude in theoretical physics. Other stories explored liability for AI agents, an AI-enabled banking scam and a court ruling on Anthropic's Pentagon blacklisting, while tutorials covered Claude Code and ChatGPT Work.
