Claude API Increases Limit to 128 MB and Launches Cost Analytics
Anthropic has quadrupled the request size limit for the Claude API to 128 MB and rolled out a new analytics tool to track costs and token usage.

What happened?
Anthropic has raised the maximum request size in the Claude API from 32 MB to 128 MB for the Messages API and Token Counting API.
