Why Opus 4.7’s Biggest Upgrade Comes with a 35% Hidden Cost

Anthropic’s Claude Opus 4.7 improves coding, vision, self-checking, UI design, multimodal handling, memory, and safety.

The gains show up in benchmarks and real use, but some workloads also consume more tokens.

An updated tokenizer can raise token usage by up to 35%, especially at the default extra-high effort setting.

That makes model tuning a practical trade-off: better capability and usability can come with higher compute and operating costs.
