Editorial excerpt
Claude Opus 5.5
AI-assisted, editorially reviewed
A premium coding candidate when better results on difficult work can justify a larger API bill.
Opus 5.5 belongs on the shortlist for difficult debugging and code review when the cost of rework matters more than the cheapest token rate. Its published rates sit below Fable 5.1 but above Sonnet 5.5. The independent results describe a maximum-effort configuration with default fallback, so test the setup you actually plan to use. Pay the premium when a small trial shows a useful improvement in finished work.
Editorial excerpt
Claude Sonnet 5.5
AI-assisted, editorially reviewed
A practical coding option to try when Opus spending is difficult to justify.
Sonnet 5.5 is a useful starting point for code review and well-scoped fixes if you want to keep API costs below Opus 5.5. That price difference is a reason to try it, not proof that it will finish every job more cheaply. Check the quality of the completed change and the amount of follow-up work. Its published results also use maximum effort with default fallback; a simpler request may behave differently.
