Opus 4.7 uses significantly more tokens than Opus 4.6 at same price
Claude Opus 4.7 uses up to 1.46x more tokens for text and 3x more for images than Opus 4.6 at the same per-token price, effectively raising costs for existing users.
I upgraded my Claude token counter tool to compare different models and Opus 4.7 appears to use 1.46x times the tokens for text and up to 3x the tokens for images - it's priced the same as Opus 4.6 on a per-token basis so this is actually a pretty big price bump simonwillison.net/2026/Apr/20/...
