Claude 3.5 Sonnet is the first model in Anthropic’s Claude 3.5 family, delivering state-of-the-art intelligence at twice the speed of Claude 3 Opus while maintaining mid-tier pricing. It sets new benchmarks in graduate-level reasoning (GPQA), undergraduate knowledge (MMLU), and coding (HumanEval), with significant improvements in understanding nuance, humor, and complex instructions. The model excels at high-quality content generation with a natural tone and demonstrates exceptional coding abilities, solving 64% of agentic coding tasks (vs. 38% for Claude 3 Opus), making it ideal for debugging, legacy code migration, and multi-step workflows. Additionally, it features enhanced vision capabilities, outperforming previous models in interpreting charts, graphs, and transcribing text from imperfect images—valuable for retail, logistics, and finance.
Available for free on Claude.ai and iOS (with higher rate limits for Pro/Team users), it also supports API access via Anthropic, Amazon Bedrock, and Google Vertex AI at 3/millioninputtokensand3/million input tokens and3/millioninputtokensand15/million output tokens. A key innovation is Artifacts, a dynamic workspace where users can edit and build upon Claude’s generated content (code, docs, designs) in real time, transforming Claude into a collaborative AI teammate.
Anthropic emphasizes safety and privacy, with rigorous testing (including by UK AI Safety Institute) and no training on user data without consent. Future releases include Claude 3.5 Haiku and Opus, along with features like Memory for personalized interactions.
