Claude Opus 4.7: Mixed Early Signal, Real API Breaks, and a Token Usage Story Anthropic Had to Address Fast

Claude Opus 4.7: Mixed Early Signal, Real API Breaks, and a Token Usage Story Anthropic Had to Address Fast Anthropic launched Claude Opus 4.7 on April 16 at the same base price as Opus 4.6, then tucked the real story inside the docs: API breaking changes, new thinking behavior, new effort controls, beta task budgets, sharper Claude Code defaults, and a multimodal bump that looks real once you read past the launch copy. 1 My first take on this release was probably too upbeat. After digging in more, the honest read is messier.
