Anthropic: Claude Opus 4
Analysis Summary
Claude Opus 4 is Anthropic's flagship model at the time of its release, combining strong reasoning, coding, and agentic capability in a single package. Its agentic index of 52.2, livecodebench of 0.636, and terminalbench hard score of 0.311 reflect genuine strength in autonomous task execution and software engineering. Vision, tool use, function calling, and a 200K context window round out a broad capability profile suited to enterprise workloads.
For business use, Claude Opus 4 is well matched to autonomous coding agents, long-document analysis, and client-facing workflows where reliability and instruction precision matter. Its ifbench score of 0.537 is among the stronger results in this batch, and its MMLU Pro of 0.873 confirms deep general knowledge. The intelligence index of 31.0 places it in the good-to-strong tier, below the very latest frontier models but well above the mid-tier field.
At $15.00 input and $75.00 output per million tokens, it is expensive and best reserved for high-value tasks. Anthropic's track record and the model's breadth of capability make it a credible enterprise choice; pair it with a cheaper model for routine or high-volume calls to manage cost.
