Claude 3 Opus, while exhibiting strong initial benchmark performance (e.g., GPQA, MMLU), has been definitively eclipsed. OpenAI's mid-May GPT-4o release reset the frontier, showcasing superior multimodal reasoning, 2x cost-efficiency over Opus, and unmatched real-time inference latency. Developer adoption metrics are already pivoting, confirming Anthropic's brief leadership has ended. Their 'Style Control' is a niche feature, not a #1 determinant. 90% NO — invalid if Anthropic releases a new model surpassing GPT-4o across all major LLM and MML benchmarks by May 30th.
