# AI Round-up: 18 September 2026

## Summary

Anthropic said Claude now leads a quarter of the work on its next AI models and shared measures for tracking development. Its research on biomolecular modelling offered a separate view of Claude's scientific capabilities, while OpenAI launched a legal-focused AI platform.

Safety and oversight featured in Amazon's call for safeguards, an open-weight partnership involving Hugging Face, and interviews with researchers and industry leaders. Practical coverage included enterprise agents, Claude Code Projects, Copilot tutorials and AI-assisted video editing.
