A Mathematical Framework for Transformer Circuits

Project Fetch: Phase two

We report results from our latest test of whether Claude can help Anthropic employees perform sophisticated robotics tasks. We found that Claude Opus 4.7, operating without human assistance, was about 20 times faster than the fastest human team at all tasks completed by participants less than a year ago.

Agentic coding and persistent returns to expertise

This report provides evidence on how Claude Code is used in practice, based on a privacy-preserving analysis of around 400,000 interactive sessions from around 235,000 people between October 2025 and April 2026.
