Unclear Where Claude Code uses this check, and what it does when the error is found, is not known.
What
Claude Code can now recognise the error the API sends when a request is rejected as unprocessable by the model because it has too many or oversized images, or unsupported parameters. It matches this message when the error has no status code or a 400 status code.
Why
On its own this changes nothing you can see. It gives Claude Code a way to tell this kind of rejection apart from other errors, which matters most in conversations with many images.
