Claude Opus 4 Sets a New AI Benchmark in 2025
Anthropic has just unveiled Claude Opus 4, and it’s already leading the pack in the world of AI performance. Backed by real benchmarks, Opus 4 delivers unmatched capabilities in coding, reasoning, math, tool use, and multilingual Q&A.
Compared to top models like GPT-4.1, Gemini 2.5 Pro, and OpenAI o3, Opus 4 shines:
Best in agentic coding (72.5% / 79.4%) — solving real-world code issues faster and more accurately
Top math performer on AIME 2025 (75.5% / 90%)
Leading multilingual understanding (88.8% on MMLU)
Strong in tool use (Retail: 81.4%) and graduate-level reasoning (83.3%)
Its sibling, Claude Sonnet 4, also brings major gains over Sonnet 3.7, especially in precision coding and airline workflow handling.
Why it matters: If you rely on AI for building, analyzing, or automating — Claude Opus 4 is now the gold standard.
