Anthropic: Claude Opus 4
Analysis Summary
Claude Opus 4 is Anthropic's earlier flagship model, with strong reasoning, coding performance, multimodal input, and reliable function calling. Its 200K context window supports long documents, codebases, and complex project instructions, while the high agentic capability makes it useful for multi-step workflows.
For businesses, it fits autonomous coding assistance, technical analysis, document review, and customer-facing content where accuracy matters. Vision and file input broaden its usefulness beyond text-only work. The main limitation is its pricing, especially for generated output, and newer Claude generations now provide stronger measured capability.
Use Opus 4 when proven agentic behaviour and deep reasoning justify premium spend. Route routine copy, classification, and high-volume automation to a cheaper model.
