Claude Opus 4.6 is Anthropic's most intelligent AI model, optimized for coding, agentic workflows, and complex reasoning tasks. It features a 1M token context window (beta), 128K max output tokens, adaptive thinking with effort levels (low, medium, high, max), and improved safety with low hallucination rates. Opus 4.6 excels in long-context tasks, production-ready code generation, debugging, and multi-step agentic processes without performance degradation.[1][2][3][4]
