1M token context window now generally available and media limit increased

The 1M token context window is now generally available for Claude Opus 4.6 and Sonnet 4.6 at standard pricing. Requests over 200k tokens work automatically for these models with no beta header required. The 1M token context window remains in beta for Claude Sonnet 4.5 and Sonnet 4.

Removed the dedicated 1M rate limits for all supported models. Your standard account limits now apply across every context length.

Raised the media limit from 100 to 600 images or PDF pages per request when using the 1M token context window.
