On Tuesday, Nvidia released Chat With RTX, a free personalized AI chatbot similar to ChatGPT that can run locally on a PC with an Nvidia RTX graphics card. It uses Mistral or Llama open-weights LLMs and can search through local files and answer questions about them.

Chat With RTX works on Windows PCs equipped with NVIDIA GeForce RTX 30 or 40 Series GPUs with at least 8GB of VRAM. It uses a combination of retrieval-augmented generation (RAG), NVIDIA TensorRT-LLM software, and RTX acceleration to enable generative AI capabilities directly on users’ devices. This setup allows for conversations with the AI model using local files as a dataset.
“Users can quickly, easily connect local files on a PC as a dataset to an open-source large language model like Mistral or Llama 2, enabling queries for quick, contextually relevant answers,” writes Nvidia in a promotional blog post.
