Using Grok 4 in the frontend development: Here’s what I’ve learned
Grok 4 dominates academic benchmarks and mathematical reasoning but struggles with practical frontend development tasks. Testing shows it requires more iterations, costs significantly more ($3.31 vs $0.30-0.47 for competitors), and delivers inferior results compared to Claude Sonnet, Gemini, or Kimi K2 for UI builds, animations, and CSS work. While excellent for algorithmic challenges and backend-heavy features, Grok 4 ranks #12 in WebDev Arena compared to Claude's #1 position, making it an expensive choice for frontend developers.
