Model Selection Tips

For Coding

Claude Sonnet 4.6, Claude Sonnet 4.5, or Gemini 2.5 Pro — excellent at code generation, debugging, and complex refactoring. For cost-effective coding, try GPT-4.1.

For Writing

Claude Sonnet 4 or Claude Sonnet 4.5 — natural writing style, great at following tone and format instructions.

For Complex Reasoning

o3, Claude Opus 4.6, or Grok 4 — when you need step-by-step thinking on hard problems. For math specifically, try DeepSeek R1.

For Quick Tasks

Claude Haiku 4.5, GPT-4.1 Nano, or Gemini 2.5 Flash Lite — fast and cost-effective for simple questions.

For Long Documents

Gemini 2.5 Pro (1M context) or Grok 4.1 Fast (2M context) — when you need to analyze large files or codebases.

For detailed model benchmarks and comparisons, check out Artificial Analysis — an independent resource for AI model performance data.
