Nathan Sobo b091cc4d9a Enforce 5MB per-image limit when converting images for language models (#45313) ... ## Problem When users paste or drag large images into the agent panel, the encoded payload can exceed upstream provider limits (e.g., Anthropic's 5MB per-image limit), causing API errors. ## Solution Enforce a default 5MB limit on encoded PNG bytes in `LanguageModelImage::from_image`: 1. Apply existing Anthropic dimension limits first (1568px max in either dimension) 2. Iteratively downscale by ~15% per pass until the encoded PNG is under 5MB 3. Return `None` if the image can't be shrunk within 8 passes (fail-safe) The limit is enforced at the `LanguageModelImage` conversion layer, which is the choke point for all image ingestion paths (agent panel paste/drag, file mentions, text threads, etc.). ## Future Work The 5MB limit is a conservative default. Provider-specific limits can be introduced later by adding a `from_image_with_constraints` API. ## Testing Added a regression test that: 1. Generates a noisy 4096x4096 PNG (guaranteed >5MB) 2. Converts it via `LanguageModelImage::from_image` 3. Asserts the result is ≤5MB and was actually downscaled --- **Note:** This PR builds on #45312 (prompt store fail-open fix). Please merge that first. cc @rtfeldman --------- Co-authored-by: Zed Zippy <234243425+zed-zippy[bot]@users.noreply.github.com>		2025-12-19 15:04:41 -05:00
