Summary
Anthropic has rolled out Opus 4.6 1M as the default model for Claude Code users across its Max, Team, and Enterprise subscription plans. The upgrade provides users with the company's most capable Opus variant, featuring an extended context window of 1 million tokens that enables developers to work with significantly larger codebases and documentation in a single session. Pro and Sonnet users can access the model by opting in through the /extra-usage command, allowing them to leverage the enhanced capabilities on demand.
Editorial Opinion
This move reinforces Anthropic's commitment to expanding Claude's utility for professional developers, particularly those working with complex, large-scale codebases. By making the most capable model the default for paying users while allowing lower-tier subscribers opt-in access, Anthropic balances accessibility with tier differentiation. The availability of a 1M context window should meaningfully improve developer productivity in code analysis, generation, and refactoring tasks.
