The Real-World AI Benchmark (Scored)
Speed and Responsiveness
Sonnet feels instant in practice. Responses stream fast enough to maintain creative flow, which matters more than most benchmarks capture. In vibe coding, the speed of the feedback loop directly impacts how quickly you can iterate on a product.
UI Generation Quality
Sonnet produces excellent UI code that needs minimal cleanup. It understands Tailwind conventions, creates proper dark mode variants, and generates accessible HTML by default. The only area where Opus clearly beats it is on complex multi-component layouts with intricate state management.
SWE-bench Performance
At 79.6% on SWE-bench Verified, Sonnet 4.6 is within 1.2 points of Opus 4.6 (80.8%). For everyday coding tasks, that gap is barely noticeable. Combined with its 89.9% GPQA score and $3/$15 pricing, Sonnet delivers exceptional bang for your buck.
Where It Falls Short
Complex agentic multi-step tasks that require maintaining state across many tool calls. For these, Opus is meaningfully better (2,011 vs 1,340 Code Arena). Also, very large codebase refactors where understanding 50+ files of context simultaneously is required.

Claude Opus 4.6: The Agentic Powerhouse
We tested Opus 4.6 across 50 real vibe coding tasks. It dominated multi-file refactors and complex agentic workflows, but the price tag limits casual use.
GPT-5.2: The GPQA King
The highest GPQA score in our benchmark (92.4%) and a strong SWE-bench showing make GPT-5.2 a serious contender, especially within the OpenAI ecosystem.
