How does Claude Opus 5 compare to Claude Fable 5 in capability and price?

Anthropic positions Claude Opus 5 as approaching Fable 5's frontier intelligence on many everyday tasks while costing roughly half as much, making it the more cost-efficient default choice for typical coding, analysis, and business-automation work.

On specific published benchmarks, the gap narrows further under higher effort settings - for example, at max effort on CursorBench 3.2, Opus 5's score lands within about half a percent of Fable 5's peak, while still costing half as much per task.

Fable 5 remains the recommended choice for the most demanding or longest-running autonomous work, such as multi-day agentic projects, where its extra capability margin is more likely to matter in practice than it does on shorter, everyday tasks.
