About Claude 3.5 Sonnet

Claude 3.5 Sonnet was Anthropic's previous generation balanced model that set new industry benchmarks when released. It demonstrated that mid-tier models could compete with and even surpass flagship models from competitors on coding, reasoning, and analysis tasks. The model featured a 200K token context window and introduced Anthropic's Artifacts feature for interactive code execution. Claude 3.5 Sonnet became one of the most popular models for professional developers and enterprises, known for its excellent code generation, careful instruction following, and reduced hallucination rates. While now succeeded by Claude Sonnet 4, it remains widely deployed in production systems and continues to offer strong performance at its price point. It was instrumental in establishing Anthropic as a serious competitor to OpenAI.
