Claude 3.5 Sonnet: AI Capabilities, Pricing and Artifacts
Claude 3.5 Sonnet stands out for one feature that many competing models lack: Artifacts. While GPT-4o and Gemini 1.5 Pro generate text and code, this model can also produce interactive dashboards, React components, charts, and formatted reports inside the same workflow. That makes it useful for developers building prototypes, analysts processing PDFs, and marketing teams creating publish-ready content.
Beyond Artifact generation, the model performs strongly in agentic coding, document extraction, AI writer workflows, and content creation. Teams use it to analyze contracts, extract structured data from invoices, generate technical documentation, and create SEO-optimized articles without switching between multiple tools.
This guide explains pricing, capabilities, Artifact workflows, coding performance, and how the model compares with GPT-4o and Gemini 1.5 Pro for real business use cases.
