About Claude 3.5 Sonnet (2024-06-20)

Claude 3.5 Sonnet (2024-06-20) launched on June 20, 2024 as Anthropic's first Claude 3.5 release, reporting stronger benchmark results than Claude 3 Opus across graduate-level reasoning (GPQA), undergraduate-level knowledge (MMLU), and coding proficiency (HumanEval). It ran at twice the speed of Claude 3 Opus while delivering higher intelligence benchmarks at Sonnet-tier cost and latency.

For coding, Anthropic reported that in an internal agentic coding evaluation, Claude 3.5 Sonnet (2024-06-20) solved 64% of problems versus Claude 3 Opus's 38%. The model could independently write, edit, and execute code with sophisticated reasoning and troubleshooting when given the right tools. Code translation (migrating legacy codebases, updating to newer frameworks) was a highlighted strength.

Vision was another meaningful upgrade. Anthropic described Claude 3.5 Sonnet (2024-06-20) as their strongest vision model at the time, surpassing Claude 3 Opus on standard vision benchmarks. Improvements were most noticeable in visual reasoning tasks like interpreting charts and graphs. The model could also accurately transcribe text from imperfect images. Anthropic called out retail, logistics, and financial services as sectors where this mattered.
