Claude Opus 4.6 and Sonnet 4.6 Now Fully Available with Million-Token Context Window

Anthropic has announced that the 1-million-token context window for its Claude Opus 4.6 and Sonnet 4.6 models is now fully available. Both models are priced at standard rates across the entire context length, with no additional premium charged for long-context usage. The specific rates are $5 per million input tokens and $25 per million output tokens for Opus 4.6, and $3 input / $15 output for Sonnet 4.6, all subject to standard rate limits across the full window. This update also raises the media processing limit per single request to 600 images or PDF pages, removes the dependency on the Beta header, and allows requests exceeding 200,000 tokens to be processed automatically. Claude Code Max, Team, and Enterprise users can now leverage the full context directly within Opus 4.6 sessions without additional consumption.
