About Claude Sonnet 5
Claude Sonnet 5 is Anthropic’s most agentic Sonnet model, designed to plan, use tools, and complete multi-step coding and knowledge tasks. It narrows the performance gap to Opus-class models while improving safety and cost efficiency across browsing, computer-use, and software workflows. The model operates through structured agent loops, decomposing tasks, browsing for context, executing terminal actions, and generating or testing code changes across files and repositories. It enforces real-time cybersecurity safeguards by default and balances cost and quality using selectable effort levels and token budgets. Sonnet 5 is accessible via the Claude API, Claude Code, or the Claude Platform, with increased rate limits supporting higher-token workloads at higher effort settings. It is best suited for teams building production agents, IDE copilots, and workflow automation across software engineering, data operations, and knowledge work, particularly those needing predictable cost-performance and standardized safety defaults.
