Claude API raises the maximum request size from 32 MB to 128 MB

Anthropic's ClaudeDevs account says the maximum request size for Messages and Token Counting on the Claude API went from 32 MB to 128 MB. It says image-heavy requests, such as long computer-use sessions and large PDFs, were hitting 32 MB with plenty of context window left, and that this gives about 4x more room.

For requests with more than 20 images, the per-image limit is also raised from 2000 px to 3000 px. Anthropic says the 128 MB limit applies to the first-party Claude API; through cloud platforms the limit is between 20 and 32 MB. The details are in the API overview documentation.
