Anthropic raises Claude API max request size from 32 MB to 128 MB

AIAnthropic says it raised the maximum request size for the Claude API's Messages and Token Counting endpoints from 32 MB to 128 MB. The change gives roughly four times more room for image-heavy requests such as long computer-use sessions and large PDFs, which previously hit the 32 MB limit with context window to spare.

We've raised the max request size for Messages and Token Counting on the Claude API from 32 MB to 128 MB.

Image-heavy requests like long computer-use sessions and big PDFs were previously hitting 32 MB with plenty of context window left. Now you get ~4x more room.
