A recent benchmark on MineBench.ai has revealed significant differences between Anthropic's Claude Fable 5 and Opus 5 models. Opus 5 demonstrated a substantially longer inference time, taking 78% longer than Fable 5, and was also 64% more expensive to run. Furthermore, Opus 5 generated JSON outputs that were three times larger on average compared to Fable 5. Despite these performance drawbacks, Opus 5 was noted for its impressive attention to detail in generated builds, correctly incorporating elements like curved screens and interior floors, which previous models failed to do.
