Antropic

Anthropic’s flagship line is Claude Opus, designed for demanding analysis, system architecture, software engineering, and agentic tasks where reasoning quality is paramount. Claude Sonnet provides a strong quality-to-speed balance, while Haiku targets high-throughput requests. For long research, large codebases, and document collections, Claude Sonnet offers a context mode of up to 1 million tokens. This makes the Claude family especially useful for multi-step tool use, code review, knowledge synthesis, and precise business writing.
