- No external libraries or dependencies. That means no Flask, Pybind and whatever. All You Need Is Python.
## Usage
- Windows binaries are provided in the form of **llamalib.dll** but if you feel worried go ahead and rebuild it yourself.
- Windows binaries are provided in the form of **llamacpp.dll** but if you feel worried go ahead and rebuild it yourself.
- Weights are not included, you can use the llama.cpp quantize.exe to generate them from your official weight files (or download them from...places).
- To run, simply clone the repo and run `llama_for_kobold.py [ggml_quant_model.bin] [port]`, and then connect with Kobold or Kobold Lite.
