 ### 1. Configuring RAGLite
 
 > [!TIP]
-> RAGLite extends [LiteLLM](https://github.com/BerriAI/litellm) with support for [llama.cpp](https://github.com/ggerganov/llama.cpp) models using [llama-cpp-python](https://github.com/abetlen/llama-cpp-python). To select a llama.cpp model (e.g., from [bartowski's collection](https://huggingface.co/collections/bartowski/recent-highlights-65cf8e08f8ab7fc669d7b5bd)), use a model identifier of the form `"llama-cpp-python/<hugging_face_repo_id>/<filename>@<n_ctx>"`, where `n_ctx` is an optional parameter that specifies the context size of the model.
