DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Claude Code v2.1.98

Model-Aware Image Processing Limits

Image processing now respects per-model limits for dimensions and file size, rather than using global constants:

  • maxWidth, maxHeight, maxBase64Size, and targetRawSize can now vary by model
  • Default limits remain at 2000×2000 pixels, 5MB base64, and ~3.75MB target raw size
  • The imageLimits parameter is threaded through clipboard paste, content processing, and tool result handling
  • Image validation now also checks images inside tool_result content blocks (not just top-level user messages)
Evidence

Image limits (search for "imageLimits" and "targetRawSize")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
