Introducing Claude Opus 4.7

Anthropic held headline rates at $5/$25 per million tokens while shipping a tokenizer that inflates inputs by up to 35%, which makes price-per-token comparisons meaningless. The capability jump is real: CursorBench up 12 points, Notion tool errors cut by two-thirds, XBOW vision nearly doubled. The only number that matters now is price-per-useful-output, and that requires workload-specific benchmarking most teams won't run.
