Claude 3 Sonnet

Claude 3 Sonnet is Anthropic's balanced Claude 3-series model that targets a strong mix of intelligence, speed, and cost-efficiency for general-purpose language tasks. It sits between the smaller Haiku and larger Opus models, and is suitable for production workloads such as customer support, content generation, and analytical reasoning.
