Claude's Opus 5 costs more than Opus 4.8 to benchmark. Opus 5 generated more tokens, labeled "very verbose".
As we reported on July 25, Claude Opus 5 has arrived with near Fable performance at half the price. New information reveals that benchmarking Opus 5 came at a cost of $3,835, exceeding that of its predecessor, Opus 4.8. Both models were found to be "very verbose" during Artificial Analysis testing, generating far more tokens than the cross-model average. This verbosity may be attributed to prompt engineering rather than fundamental model improvements.
The cost of benchmarking Opus 5 is significant, and its implications are noteworthy. Despite the higher cost, Opus 5 has been shown to offer comparable intelligence to Fable 5 at a lower cost per task. This development is crucial in the context of sectorwide security concerns and the ongoing quest for efficient and effective AI models.
Looking ahead, it will be essential to monitor how Opus 5 performs in real-world applications and how its cost per task compares to other models, including Fable 5. As Opus 5 is now available on the API and is the default on Claude Max, its impact on the industry will be closely watched.
