Claude 3 Sonnet

Balanced mid-tier model with 2x speed improvement over Claude 2; strong enterprise performance at moderate cost.

Claude 3 Sonnet released March 4 2024 offered the ideal balance of intelligence and speed for enterprise workloads. Running 2x faster than Claude 2 and 2.1 it delivered higher intelligence levels while keeping costs manageable. The model powered the free claude.ai experience and excelled at complex tasks including customer support sophisticated coding document analysis and multilingual conversations. It introduced improved vision capabilities for processing photos charts graphs and technical diagrams. Sonnet demonstrated enhanced capabilities in forecasting nuanced content creation code generation and non-English languages including Spanish Japanese and French. Enterprise users adopted it widely for production workflows where consistent performance and reasonable throughput mattered more than maximum capability. Retired July 2025.
