Anthropic increased the single-request payload limit for Claude API's Messages and Token Counting endpoints from 32 MB to 128 MB. This change addresses bottlenecks in long-running Computer Use tasks and large PDF processing, where file size constraints previously triggered errors despite ample context window availability. Additionally, the per-image resolution cap for multi-image requests was raised from 2000 to 3000 pixels to better leverage model visual capabilities. The update applies exclusively to the official Anthropic API.
