Detailed analysis
Intelligence & Performance
Winner: Claude Opus 4.7Claude Opus 4.7 provides a concrete intelligence_index of 53.5 and output speed of 50.25 t/s. Claude Sonnet 4 lacks published values for these metrics. Both models emphasize strong reasoning, but only Opus 4.7 supplies quantifiable data.
Pricing
Winner: Claude Sonnet 4Claude Sonnet 4 is priced at $15/1M tokens compared to Claude Opus 4.7 at $25/1M. Both are proprietary Anthropic models with identical 1M context windows. The $10/1M difference favors Sonnet 4 for budget-conscious multimodal workloads.
Multimodal Capabilities
Winner: Claude Opus 4.7Claude Opus 4.7 explicitly lists versatility with text, image, and file inputs plus effective large-context handling. Claude Sonnet 4 notes effective multimodal integration but states no native audio or video support. Both share the same context length and safety focus.
Safety & Limitations
Winner: TieBoth models highlight careful safety alignment and conservative refusals on sensitive topics. Opus 4.7 notes higher latency on complex tasks and no real-time web access; Sonnet 4 may prioritize caution over maximum helpfulness. No clear differentiator exists in the provided facts.
