This is a dev post classified by AGK Intelligence as Backend & APIs (a launch), kept by the Dev Radar because it carries real work, not commentary.

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.
