Claude Opus 4.6
Claude Opus 4.6, Anthropic's flagship LLM released February 5, 2026, was superseded by Opus 4.7 just 70 days later. Despite its short reign, the model still competes directly with GPT-4 Turbo, Gemini 2.0, ChatGPT, and even Anthropic's own Claude Mythos Preview. With an 80.8% SWE-bench Verified and 58% CursorBench, it remains a coding powerhouse. It deploys Constitutional AI and Chain-of-Thought Prompting, and is used by Claude Code, Navox Agents, and Automated Alignment Researchers. Its 1M-token context window and 128k max output are still industry-leading. But mention counts have dropped to 3 in the last 7 days, signaling fading attention. The model is now a bridge between Opus 4.5 and 4.7, not the destination.
