Claude 4.6 compressed to 1280x720, Opus compressed to 1080p, remember these two thresholds, don’t wait until the coordinates fly away and then regret.

Official guide disclosure: Claude 4.6 has a maximum long side of 1568 pixels, Opus 4.7 is 2576 pixels; screenshots exceeding the limit will be scaled proportionally, causing coordinate misalignment, so it is necessary to first resize on the client to 1280x720 (Claude) or 1080p (Opus). Testing shows that Opus 4.7 at low thinking depth can match Sonnet 4.6's maximum depth, with token costs only one-tenth of the latter, and it is recommended to set the thinking option to high, saving half of the tokens compared to max with the same success rate.
