Claude Sonnet 5

①Powerful Agentic Capabilities
Autonomously plans and executes multi‑step, complex tasks, and can run independently for extended periods without stopping midway. Handles end‑to‑end workflows—such as complete software engineering projects—with minimal need for human intervention.

② Tool Use
Proficiently uses external tools like browsers and terminals. Performs strongly on benchmarks for agentic search and computer use.

③Coding & Debugging
Delivers excellent coding performance, capable of tackling complex software engineering tasks. Actively debugs on its own, even without being prompted to do so.

④Multi‑step Reasoning & Knowledge Work
Shows substantial improvements over the previous Sonnet 4.6 in reasoning, tool use, and coding. Approaches the performance of the more powerful Opus 4.8, while maintaining a lower cost.

⑤Enhanced Safety
Exhibits lower rates of undesirable behavior than Sonnet 4.6, with better safety performance in agentic scenarios. Network‑security capabilities are significantly more restricted than those of the Opus series, with network protection enabled by default.

①Developers & Software Engineering Teams
The core audience. Ideal for coding, debugging, and handling complex software engineering workflows—can autonomously complete end‑to‑end coding tasks.

②Teams & Enterprises Building AI Agents
Designed for those developing products or workflows that require autonomous planning, tool use (browsers, terminals, etc.), and long‑running independent operation.

③Knowledge Workers & Researchers
Well‑suited for those who need multi‑step reasoning, information retrieval (agentic search), and data organization and analysis.

④Cost‑Sensitive Users & Enterprises
Delivers performance close to Opus 4.8 at a lower price point—an excellent choice for teams seeking high cost‑effectiveness and large‑scale API usage.

⑤Security‑Conscious Scenarios
Features lower rates of undesirable behavior and default‑enabled network protection—ideal for enterprise‑level deployments with strict compliance requirements.

⑥Claude Users at All Tiers
Available across all plans: free and Pro users get it as the default, while Max, Team, and Enterprise plans can also access it—covering a broad range of users from individuals to large organizations.
