GoKawiilClaude Opus 5.5 scores 58 on Artificial Analysis Intelligence Index, priced above median
Anthropic's Claude Opus 5.5, running in Adaptive Reasoning Max Effort mode, scored 58 on the Artificial Analysis Intelligence Index against a median of 25 among comparable models. The model handles text and image input with text output and a 1M token context window, but is priced at $4.00 per 1M input tokens and $20.00 per 1M output tokens, both above the reported medians of $2.00 and $10.00. Evaluating it on the Intelligence Index generated 260M tokens and cost $8,708.20 in total.
GoKawiil's interpretation of the reporting above, not reported fact.
The high token usage during evaluation suggests the model tends toward verbose reasoning, which could translate into higher real-world costs for developers even before accounting for its above-median per-token pricing. This positions Claude Opus 5.5 as a strong performer on intelligence benchmarks but a costlier choice relative to peers, a tradeoff that could matter for teams optimizing for budget rather than raw capability.
- Claude Opus 5.5 scored 58 on the Intelligence Index versus a 25 median for comparable models
- Input pricing is $4.00 per 1M tokens and output pricing is $20.00 per 1M tokens, both above median
- The model used 260M tokens during evaluation, far more than the 92M median, costing $8,708.20 total
