Step 5: Explore the Interface

LM Studio has several useful features:

Chat Tab:

• Temperature and sampling controls
• Multiple conversation threads

Search Tab:

• Browse available models
• Filter by size, quantization, and popularity
• See RAM requirements before downloading

Local Server Tab:

• Run an OpenAI-compatible API server
• Use LM Studio as a backend for other applications
• Configure the port and CORS settings

Step 6: Use the API Server (Optional)

LM Studio can act as a drop-in replacement for the OpenAI API:

1. Go to the Local Server tab (developer icon in sidebar)

You can now point any OpenAI-compatible application to this URL.

Tips for Best Performance

• Close other apps — free up RAM for the model
• Use Q4_K_M quantization — best quality/size balance
• Match model size to your RAM — 8B models for 8GB RAM, 14B for 16GB
• Enable GPU acceleration — LM Studio auto-detects NVIDIA GPUs and Apple Metal
• Use the right model for the task — check our 8GB RAM model guide for recommendations
