OpenAI vs Hugging Face
Use OpenAI (or Claude) for reasoning and tool calling. Use small Hugging Face models for high-volume embeddings, classification and private data.

Analogy
You don't hire a senior architect to sort the mail. Use the cheap specialist for narrow jobs.
In an agent
Model choice is a cost, quality and privacy trade-off. Good agents mix both.

Flashcards
- Interview: when do you pick an open-source model?High-volume narrow tasks (embeddings, classification), strict privacy, or when cost per call matters.
Interview questions
- When would you use an open-source model?
- High-volume narrow tasks like embeddings and classification.
- Strict privacy requirements, or when cost per call matters.
- In DevPilot, Hugging Face models do embeddings and PR classification locally in Node.
Questions people ask
Should I use OpenAI or Hugging Face models for my agent?
Usually both. Use OpenAI or Claude for reasoning and tool calling, where a large model is worth paying for. Use small Hugging Face models for high-volume, narrow jobs such as embeddings and classification, or wherever data must stay private. Model choice is a trade-off between cost, quality and privacy.
How do I mix OpenAI and open-source models in one agent?
Give each model the job it is best at. A local classifier routes the request, local embeddings power document search, and a hosted LLM does the reasoning and tool calls. Each runs behind its own function or tool, so the agent loop does not care which provider answered.
