# AI Models Reference Skill


**Last Updated: December 2025**

## Philosophy

**Use the right model for the job.** Bigger isn't always better - match model capabilities to task requirements. Consider cost, latency, and accuracy tradeoffs.

## Model Selection Matrix

| Task | Recommended | Why |
|------|-------------|-----|
| Complex reasoning | Claude Opus 4.5, o3, Gemini 3 Pro | Highest accuracy |
| Fast chat/completion | Claude Haiku, GPT-4.1 mini, Gemini Flash | Low latency, cheap |
| Code generation | Claude Sonnet 4.5, Codestral, GPT-4.1 | Strong coding |
| Vision/images | Claude Sonnet, GPT-4o, Gemini 3 Pro | Multimodal |
| Embeddings | text-embedding-3-small, Voyage | Cost-effective |
| Voice synthesis | Eleven Labs v3, OpenAI TTS | Natural sounding |
| Image generation | FLUX.2, DALL-E 3, SD 3.5 | Different styles |
