Anthropic has raised the maximum request size for Messages and Token Counting on the Claude API from 32 MB to 128 MB. Anthropic said that long-running computer-use sessions and image-heavy requests such as large PDFs previously hit the 32 MB limit while the context window still had room to spare. The same source also stated that for requests with more than 20 images, the per-image limit has been increased from 2000 px to 3000 px; the 128 MB limit applies only to the first-party Claude API, while calls made through cloud platforms are capped between 20 and 32 MB. There are currently no further developments.
