Also known as: Claude Opus 4.8,Claude Opus 4.7
Claude Opus is Anthropic's top-tier model family. Opus 4.8 (released June 2026) is currently the strongest published model on SWE-Bench Verified coding (89.7%) and GPQA Diamond reasoning (94.3%), narrowly leading GPT-5 and Gemini 3.5 Pro. Key features in 2026: extended thinking up to 60 minutes for hard problems, tool-use reliability at 96%, and a 500k-token context window. Pricing: $12.50 input / $75 output per million tokens, with prompt caching cutting input cost by ~90%. Best for: serious coding work, long-document analysis, agentic workflows. Less suited for: casual chat (slower than GPT-5), multimodal video (Gemini leads).
