First token counts reveal Opus 4.7 costs significantly more than 4.6 despite Anthropic's flat pricing

Anthropic kept Opus 4.7’s list prices flat versus 4.6, but new measurements suggest it uses more tokens per request.

A developer report and community benchmark found the increase varies by content type and can reach roughly 37% more tokens and cost.

That means users may pay more for the same workload, making model choice and prompt design more important for budgeting.
