Claude API raises the maximum request size from 32 MB to 128 MB
Anthropic's Claude API release notes for 28 October say the maximum request size for the Messages API and the Token Counting API has gone up from 32 MB to 128 MB. The change applies to the first-party Claude API; the note does not mention Amazon Bedrock, Google Cloud or Microsoft Foundry.
Why it matters: If your app sends large PDFs, scans or image-heavy files to Claude and you have been splitting them to stay under 32 MB, try sending them in one request on the Claude API and compare cost and quality.
