  • New xhigh effort level: a new level that lets you tune reasoning depth more finely.
  • Task Budgets: lets you set a token-budget cap for long-running agent tasks.
  • Supports a 1M context window and high-resolution vision.

Note: tokenizer change

Opus 4.7 uses a new tokenizer, so the same input may produce more tokens. Pricing is unchanged, but watch for changes in actual token consumption.
