Anthropic: Claude Sonnet 4.6
Analysis Summary
Anthropic's Claude Sonnet 4.6 is a high-capability production model with strong reasoning, coding, and agentic results. It provides a million-token context window, vision and file input, tool use, and function calling, giving teams a unified model for long documents, codebases, visual materials, and multi-step operations. The combination is particularly useful when accuracy and instruction following must remain consistent across a large working set.
Agency workloads include software engineering, content quality control, strategy research, complex SEO briefs, document analysis, and customer-facing assistants. Its agentic capability is strong enough for tool-driven workflows, while human approval remains appropriate for irreversible actions and sensitive client operations. The primary limitation is cost, especially when output volume is high.
Sonnet 4.6 is a strong default for demanding client workflows. Pair it with a cheaper model for classification, simple drafting, and routine transformations.
