Source Intelligence

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.

Image and PDF read limits are now explicit profiles

Under the hood
Useful3 Signal2
File Reading

Image and PDF read limits are now fixed profiles: 3 PDF pages, images downscaled to 2000x2000.

What

Limits on reading images and PDFs are collected into named profiles, chosen by a switch between session and default settings. Raw images are capped at 307200 bytes, a PDF read covers at most 3 pages, and oversized images are downscaled to fit 2000x2000 and 5242880 bytes of encoded data.

Details
  • The whole-PDF read budget in one profile is 0 bytes, so PDFs go through the per-page path rather than being read in full.
  • Which profile applies is decided per session rather than globally.
