Claude 4.5 Sonnet

Claude 4.5 Sonnet is Anthropic's enhanced mid-tier model, advancing the Claude 4 Sonnet line with notable improvements on coding, agentic, and tool-use benchmarks. The release positioned Claude 4.5 Sonnet as the strongest production-grade model for software engineering and agentic workflows at its price tier — extending Anthropic's reputation for excellence in coding-heavy applications. The model continues to support extended thinking with configurable depth, vision input, function calling, Computer Use, and the 200K-token context window. Real-world deployments include AI coding assistants (Cursor, Cline, Aider, Anthropic's own Claude Code), agentic task automation, customer-support escalation handlers, and complex document analysis pipelines. Pricing remains in the Sonnet tier ($3 input, $15 output per million tokens). The model became one of the most widely-adopted production LLMs in late 2025 and 2026. AI governance, AI compliance, and AI risk management programs continue tracking version migrations supporting responsible AI through clear model-version inventories in enterprise AI environments.
