This is a demo of [`MBZUAI-Paris/Atlas-Chat-2B`](https://huggingface.co/mbzuai-paris/atlas-chat-2b). For more details, please check [the paper](https://arxiv.org/pdf/2409.17912).
Looking for a larger and more powerful version? Try the 9B version in [HuggingFace](https://huggingface.co/mbzuai-paris/atlas-chat-9b).
This demo was done using the [llama-cpp-python](https://github.com/abetlen/llama-cpp-python) library for efficient inference and is running the [`mradermacher/Atlas-Chat-2B-GGUF`](https://huggingface.co/mradermacher/Atlas-Chat-2B-GGUF) version with 8-bit Q8_0 quantization.
