1M context is now generally available for Opus 4.6 and Sonnet 4.6

Anthropic says its 1 million token context window is now generally available for Claude Opus 4.6 and Sonnet 4.6, and the main change is that developers no longer pay a premium for using the larger window. The post says standard pricing now applies across the full context size, full rate limits still work at every length, and media limits have expanded from 100 to 600 images or PDF pages per request. Anthropic also says requests over 200,000 tokens no longer need a beta header, and that Claude Code users on Max, Team, and Enterprise plans with Opus 4.6 now get the larger context automatically. The broader pitch is that this should let people work with much larger codebases, documents, and long-running agent sessions without repeatedly compacting context or losing important details.
