1M Token Context Window Now GA

Anthropic has graduated the 1M token context window to general availability for Claude Opus 4.6 and Claude Sonnet 4.6, making it available at standard pricing with no beta header required. Requests exceeding 200k tokens now work automatically on these models, removing friction from the development workflow.

Rate Limits and Media Handling Simplified

As part of the release, Anthropic has eliminated the dedicated 1M rate limits that previously existed for supported models. Your standard account limits now apply uniformly across all context lengths, simplifying quota management and pricing predictability. The media handling limit has also been significantly expanded from 100 to 600 images or PDF pages per request when using the 1M token context window—a 6x increase that enables more sophisticated document processing and vision workflows.

What This Means for Developers

Developers can now build applications requiring extended context without worrying about beta limitations or special configuration. The unified rate limiting and expanded media support make it feasible to process large documents, long conversation histories, and multi-image analysis in a single API call. The 1M token context remains in beta for Claude Sonnet 4.5 and Sonnet 4.
