Update
What changedAnthropic’s Claude Opus 5.5 is being presented as roughly 40% cheaper to run than Opus 5, with reported pricing of $4 per million input tokens and $20 per million output tokens. That gives developers a more useful measure of the launch than the promise of lower cost alone.
The Decoder reports that Anthropic says Opus 5.5 matches Fable 5.1 on most tasks while costing about 40% less than Opus 5. Those are Anthropic’s comparisons, not independent benchmark findings, and the supplied evidence does not establish how the models were tested or which workloads produced the saving.
The practical change is that teams can now begin comparing the model against their own usage bills rather than treating “cheaper” as a decorative adjective. The reported rates may make Opus 5.5 more attractive for high-volume applications, but output-token consumption, latency and task success will decide whether the saving survives contact with real workloads.
