Apply the debias vector and either the positive or negative vector when starting llama-server. If both are applied, they will cancel each other out.

You can use either --control-vector [/path/to/vector.gguf] or --control-vector-scaled [/path/to/vector.gguf] [scale factor]

The debias vector must be set to 1.0

IMPORTANT: The positive and negative axis control vectors must be used along with the relevant de-bias control vector - they cannot be used on their own!

Limitations

With reasoning enabled on extreme quants like IQ2_XXS, very simple prompts like "Hi" may result in irrelevant replies.
