Anthropic: Claude Opus 4.6
Analysis Summary
Claude Opus 4.6 is Anthropic's previous-generation flagship, with an intelligence index of 43.7 and an agentic index of 69.2. It supports vision, file input, tool use, and function calling across a 1 million token context window, making it one of the most capable all-round models available. GPQA of 0.896 and a tau2 of 0.921 confirm strong reasoning and task reliability, while the LCR of 0.707 shows it handles long documents well.
For businesses, this model suits complex coding tasks, autonomous agent workflows, long-document analysis, and high-quality client-facing content generation. The breadth of modality support (text, image, file) means teams can consolidate multiple use cases on a single model. The main trade-off is cost: at $25 per million output tokens, it is expensive for high-volume use.
Opus 4.6 remains a strong production choice for high-value, low-volume tasks where reasoning depth and reliability justify the premium. Newer Anthropic flagships now lead on benchmarks, but this model holds its own against the broader field.
