Anthropic moved the 1M token context window to general availability for Opus 4.6 and Sonnet 4.6 at standard pricing. Auto-activates for requests over 200K tokens. Media limit increased from 100 to 600 images/PDFs per request. The new thinking.display: 'omitted' flag for streaming extended thinking without surfacing reasoning blocks reduces bandwidth for agentic callers. Quietly removes one of the biggest friction points for long-document and multi-file workflows.
