Detailed Comparison
A side-by-side analysis of key factors to help you make the right choice.
| Factor | Claude Opus 4Recommended | Claude Sonnet 4 | Winner |
|---|---|---|---|
| Reasoning Depth | Exceptional depth for complex analyses, multi-step planning, and scientific tasks. Best when errors are costly. | Strong reasoning for most production tasks. Minor quality reduction on highly complex problems, sufficient for 90% of use cases. | |
| Speed | Slower. Typical TTFT 1-3s, TPS 30-60. Suboptimal for real-time interactive applications. | 2-3x faster than Opus. Typical TTFT 300-800ms, TPS 50-100+. Ideal for latency-sensitive applications. | |
| Cost | 4-5x more expensive per token. Only economically justified for use cases with clear quality requirements. | Better price-performance for most production workloads. Enables 4-5x more volume at same budget. | |
| Code Quality | Excellent for complex architectural decisions, code review, and algorithmically challenging implementations. | Very good for most coding tasks. Slightly behind Opus on highly complex algorithms. | |
| Context Understanding | Superior comprehension of long, complex documents and deeply nested dependencies. | Very good context understanding. Small quality drop with very long contexts (>100k tokens). | |
| Price-Performance | Optimal for: strategic analyses, legal documents, scientific research, safety-critical code. | Optimal for: content generation, standard coding, chatbots, translation, SEO - 80% of all AI workflows. | |
