About
Claude 3 Sonnet by Anthropic is a versatile large language AI model, balancing intelligence and speed for diverse enterprise use cases. It is part of the Claude 3 family, positioned between the powerful Opus and the faster Haiku models. Sonnet excels in nuanced content creation, accurate summarization, and complex scientific query handling while also showcasing proficiency in non-English languages and coding tasks. Additionally, it enhances vision capabilities with exceptional skills in visual reasoning, such as interpreting charts, graphs, and transcribing text from imperfect images, which benefits industries like retail, logistics, and finance. Operated at twice the speed of Claude 3 Opus, Sonnet is efficient in context-sensitive customer support and multi-step workflows. It has achieved AI Safety Level 2 (ASL-2) and is accessible through multiple platforms, including Claude.ai, the Claude iOS app, the Anthropic API, Amazon Bedrock, and Google Cloud's Vertex AI.
Claude 3 Sonnet is a proprietary model in the Claude 3 family. The structured metadata tracks a 200k-token context window, multimodal input, reasoning, structured outputs, and code execution. This page tracks provider routes through AWS Bedrock, GCP Vertex AI, and Anthropic, with the cheapest tracked route listed at $3 input and $15 output per 1M tokens. Headline tracked benchmarks include Massive Multi-discipline Multimodal Understanding 53.1.
