## Summary

Claude Opus 4.6 represents a major upgrade to Anthropic's flagship AI model, featuring enhanced coding capabilities, improved agentic task performance, and a 1M token context window. The model achieves state-of-the-art results on multiple benchmarks including Terminal-Bench 2.0, Humanity's Last Exam, and GDPval-AA, outperforming competitors like GPT-5.2 by significant margins. Key improvements include better code review, debugging, long-context retrieval, and the ability to handle complex multi-step tasks autonomously. New API features include adaptive thinking, effort controls, context compaction, and 128K output tokens. Product updates bring agent teams to Claude Code and enhanced Excel/PowerPoint integrations. Despite increased capabilities, the model maintains strong safety profiles with low rates of misaligned behavior and includes enhanced cybersecurity safeguards.
