Once the server starts, you can access the Oobabooga UI by opening the provided URL (e.g. http://localhost:7860) in your web browser. The UI provides an intuitive interface for loading models, adjusting settings, and interacting with the LLM.

Loading and Running Models

With Oobabooga up and running, the next step is to load a GenAI model. Oobabooga makes it easy to download models directly from HuggingFace. Here‘s how:

1. In the Oobabooga UI, navigate to the “Model” tab and scroll down to the “Download Custom Model” section.
2. Enter the HuggingFace model path in the provided text field. For example, to download the 7B parameter GPTQ-quantized version of the Nous Hermes Llama model, enter:

   TheBloke/Nous-Hermes-13B-GPTQ:GPTQ-4bit-32g 
   

3. Click the “Download” button to download the model. Depending on the model size and your internet speed, this may take some time.
4. Once the download is complete, click the “Refresh” button and select the downloaded model from the drop-down menu.
5. If using a GPU-optimized model like GPTQ, you‘ll need to allocate GPU memory by entering the amount (in GB) in the “GPU Memory” field. For example, entering “8” will allocate 8GB of VRAM to the model. Then click “Load”.
6. After the model loads, navigate to the “Text Generation” tab. Here you can enter prompts and adjust parameters (max length, temperature, etc.) to interact with the model.

And that‘s it! You now have a powerful GenAI language model running entirely on your local machine, ready to assist with a wide range of natural language tasks. In the next section, we‘ll discuss some of the key benefits of this local LLM approach.
