They have switched tokenizer to one that generates 1-1.35x (i.e. up to 35% more) tokens for the same input.

They have changed default CC effort to xhigh.

They have said that Opus 4.7 will generate more tokens than 4.6 at same effort level.

They have increased their image input resolution meaning more tokens per image.

etc.

Maybe they are also extracting another 5% tokens from you by prompting it to not talk like a caveman, but that would hardly be noticeable.
