Anthropic: Claude 3.5 Sonnet
Analysis Summary
Claude 3.5 Sonnet is Anthropic's mid-2024 flagship, combining strong coding performance (index 30.2, livecodebench 0.381) with vision, tool use, function calling, and a 200K context window. MMLU Pro of 0.772 reflects broad knowledge coverage, and the model handles file inputs alongside text and images, making it one of the more capable multimodal options at this tier.
For businesses, it is a strong fit for software engineering assistance, code review, long-document analysis, and client-facing content generation. The combination of coding strength, vision, and large context makes it versatile across technical and editorial workflows. Its intelligence index of 15.9 is lower than newer generation models, so it is not the right choice for the hardest reasoning tasks.
At $6.00 input and $30.00 output per million tokens, it is expensive. Teams should reserve it for high-value tasks where coding quality and multimodal capability justify the cost, and pair it with a cheaper model for routine or high-volume calls.
