AGT.12.03 Mid-level

Running open-weight models locally

Comes up in: AI engineering

This concept is being written. It gets the full five steps — explanation, predict, interview angle, practice with tests, and review cards. Here is exactly what it will cover, so you can study it elsewhere in the meantime.

What it covers

  • open-weight model families (licence differences)
  • quantisation (GGUF, 4-bit) and quality trade-offs
  • Ollama, llama.cpp, LM Studio, vLLM
  • hardware needs
  • OpenAI-compatible local endpoints
  • privacy and offline use cases
