Oobabooga's Text Generation Web UI is a remarkably versatile tool that makes running powerful AI language models a breeze, right from your own computer – and the best part? It's completely free!
What is Oobabooga's Text Generation Web UI?
This amazing tool has been a mainstay in the open-source text generation landscape, serving as a gateway for countless AI enthusiasts. It's packed with features, providing a user-friendly interface to interact with large language models (LLMs) like Transformers, llama.cpp, and ExLlamav2.
Here's a sneak peek at some of its impressive capabilities:
- Multiple backends: Seamlessly integrate with various text generation backends, including popular choices like Transformers, llama.cpp, and ExLlamav2.
- OpenAI compatibility: Enjoy the convenience of an OpenAI-compatible API server.
- Automatic prompt formatting: No more struggling with prompt structures, let the tool handle the formatting for you.
- Flexible chat modes: Engage in both casual and instruction-based conversations with ease.
- LoRA fine-tuning: Personalize your models with LoRA fine-tuning for truly bespoke results.
But Don't I Need a Supercomputer?
You might be thinking, "This sounds amazing, but don't these AI models require massive computing power?"
Fear not! We'll be leveraging the magic of Google Colab, a cloud-based platform that grants access to powerful T4 GPUs with 16 GB of VRAM. This means you can run these impressive models directly in your browser, regardless of your computer's specs!

Setting Up Oobabooga's Text Generation Web UI with Google Colab
I've created a streamlined Colab notebook to make this setup ridiculously easy. You can access it through the link provided in the resources section below.
Here’s a step-by-step guide to get you started:
Sign in: Ensure you’re logged into your Google account to run the Colab notebook.
Connect to runtime: Connect to a Colab runtime and crucially, enable the T4 GPU in the notebook settings. This is essential for running the models.
Run the code: You’ll see four code modules in the notebook. Simply run each module in order by clicking the play button next to them. Don't worry, each module has clear explanations so you understand what's happening.
Here's a breakdown of what each code module does:
- Module 1: Clones the Oobabooga repository to your Colab environment.
- Module 2: Imports the necessary Python modules for running the Web UI.
- Module 3: Installs all the required dependencies for the project.
- Module 4: Launches the Text Generation Web UI and provides you with a shareable public link to access it.
The entire setup should only take a few minutes, and requires minimal effort thanks to the simple three-line code structure.
Choosing Your AI Model
With the environment ready, it's time to pick your AI model! Head over to Hugging Face, a vast repository of open-source AI models. You'll find an extensive selection to choose from, so you're sure to discover one that fits your needs. Just make sure it’s compatible with your Colab runtime resources and supported by the Oobabooga Web UI.
For this example, we'll be using the new llama 3.2 3B model with ExLlama 12-bit quantization which is designed for GPU execution.
Downloading the Model
Copy Model Name: Find the model you want on Hugging Face and copy its full name, including the branch name if applicable.
Paste and Download: In the Oobabooga Web UI, paste the model name into the designated area within the "Model" tab and click "Download."
Monitor Progress: You can track the download progress in the Colab notebook.
Remember: The free version of Colab erases session data when the runtime ends. If you're working on something important, save it to your Google Drive before closing your session.
Loading the Model
Once the model is downloaded, select it from the dropdown menu in the "Model" tab. If you are using a Exllama model, ensure you are using the ExLlamav2_HF model loader setting. Enable 8-bit caching and disable flash attention. Click the “Load” button, and you’ll see a confirmation message once it's loaded.
Let the Chat Begin!
Before we jump into chatting, we'll need to configure the Web UI for instruction-based prompts.
Instruction Template: In the “Parameters” tab, select “Instruction template” and choose "Llama V3" from the dropdown menu. Click "Load."
Generation Preset: Go to the “Generation” tab and select the “LLaMA Precise” configuration preset.
Chat Away: Navigate to the “Chat” tab, type your prompt in the text box, and hit “Generate!”
You can always tweak the parameter settings to find the perfect configuration for your chosen model. Experiment with different chat modes, adjust generation parameters, and even fine-tune your models with LoRA for personalized results.
Open-Source AI at Your Fingertips
That’s all it takes! With just three lines of code, you have unlocked the power of large language models right on your computer.
Oobabooga's Text Generation Web UI and Google Colab provide a powerful and accessible platform for anyone interested in exploring the ever-expanding world of open-source AI.
