# Comment out values as needed. Every value has a default within the application.

# Unless specified in the comments, DO NOT put these options in quotes!
# You can use https://www.yamllint.com/ if you want to check your YAML formatting.

# Options for networking
network:
  # The IP to host on (default: 127.0.0.1).

  # The port to host on (default: 5000)
  port: 5000

# Options for logging

  # Enable generation parameter logging (default: False)
  generation_params: False

# Options for model overrides and loading
model:

  # Windows users, DO NOT put this path in quotes! This directory will be invalid otherwise.
  model_dir: your model directory path

  # An initial model to load. Make sure the model is located in the model directory!
  # A model can be loaded later via the API.
  model_name: A model name

  # Sends dummy model names when the models endpoint is queried
  # Enable this if the program is looking for a specific OAI model
  use_dummy_models: False

  # The below parameters apply only if model_name is set

  # Maximum model context length (default: 4096)

  # Enable 8 bit cache mode for VRAM savings (slight performance hit). Possible values FP16, FP8. (default: FP16)
  cache_mode: FP16

  # Set the prompt template for this model. If empty, fastchat will automatically find the best template to use (default: None)
  # NOTE: Only works with chat completion message lists!
  prompt_template:

  # Options for draft models (speculative decoding). This will use more VRAM!
  draft:
    # Overrides the directory to look for draft (default: models)
    draft_model_dir: Your draft model directory path

    # An initial draft model to load. Make sure this model is located in the model directory!

  # Options for loras
  lora:
    # Overrides the directory to look for loras (default: loras)
    lora_dir: Your lora directory path
    
    # List of loras to load and associated scaling factors (default: 1.0). Comment out unused entries or add more rows as needed.
