First successful setup

  1. Install LM Studio.
  2. Download one model that fits your available memory.
  3. Load it with ordinary settings and get a successful chat before changing context or server settings.

What success looks like: the model loads without memory pressure and returns a normal chat response.

Choose something else when

  • treating the vendor's entire product line as local-only;
  • multi-user self-hosted web interfaces;
  • assuming offline or private behavior without checking the selected path;
  • performance claims without named hardware and reproduced testing.
