Model Settings

Click the gear icon next to any model to adjust how it behaves:

Basic Settings:

  • Context Size: How much conversation history the model remembers
  • GPU Layers: How much of the model runs on your graphics card (higher = faster, but uses more GPU memory)
  • Temperature: Controls creativity (0.1 = focused, 1.0 = creative)

Advanced Controls:

  • Top K & Top P: Fine-tune how the model picks words (lower = more focused)
  • Min P: Minimum probability threshold for word selection
