When to choose each
Claude Opus 5.5
Best for
- Long-running agentic coding and knowledge work as the general-purpose default
- Cache-heavy agent loops where the 0.05x read multiplier compounds
Watch out for
- The API effort default is medium here, not high as on Claude Fable 5.1 and Claude Sonnet 5.5, so a like-for-like comparison has to set effort explicitly
- The 4.7-generation tokenizer produces roughly 30% more tokens for the same text than Claude Sonnet 4.6 and earlier, so per-token rates do not compare directly across generations
Muse Wonder
Best for
- Multi-file coding changes and multi-hour agent runs
- Sub-agent orchestration where capability matters more than cost
Watch out for
- Meta lists it as a preview, and the Model API serves Standard mode only, with no discounted Contributor tier
- The higher-capability Muse Wonder Full is only available through Muse Code subscriptions, not per token
- Released after the latest Arena and Epoch AI snapshots, so no independent score is recorded yet
