Use cases and recommendations
Chatbots and customer support
For high-volume chatbots, Claude Haiku 4.5 offers the best cost-to-performance ratio. For more complex conversations requiring nuanced understanding, Claude Sonnet 4.5 provides better accuracy at a moderate cost increase.
Code generation and analysis
Claude Sonnet 4.5 and Claude 3.7 Sonnet excel at coding tasks. They can understand entire codebases, generate code, and perform code reviews with high accuracy.
Research and analysis
For complex reasoning tasks, research analysis, and document understanding, Claude Opus 4 provides the highest accuracy. It's ideal for legal, medical, and scientific applications where precision matters.
Long document processing
All Claude models support large context windows (200K tokens), making them excellent for processing lengthy documents, research papers, and codebases.
Cost optimization tips
- Use prompt caching: Anthropic supports prompt caching to reduce costs for repeated contexts
- Batch processing: Group multiple requests together for lower costs
- Right-size your model: Use Haiku for simple tasks, Sonnet for balanced work, Opus for complex reasoning
- Monitor token usage: Track input/output tokens to identify optimization opportunities
- Use streaming: For real-time applications, streaming can improve user experience
