BullsAI Chat provides access to a curated selection of open-weight large language models. These models are developed by major AI companies and research labs, then made available for institutions like UB to run on their own infrastructure.

That means BullsAI can offer access to powerful AI models through a UB-hosted environment rather than relying only on public chatbot services.

Available models may change as new models are added, tested, updated or retired. Check the model selector in BullsAI Chat to see the currently available options.

BullsAI Chat lets you compare responses from multiple large language models in the same conversation.

Use the Add a model option to send the same prompt to two or more selected models at once. BullsAI Chat displays the responses side by side or stacked, making it easier to compare answers, check facts, test writing styles, and see how different models approach the same task.

This is especially useful when you want to:

• Compare reasoning or explanations
• Check whether answers agree or conflict
• Test which model works best for a specific task
• Evaluate strengths and limitations across models
• Use AI with text, documents and images

BullsAI Chat supports more than basic text prompts. Depending on the selected model and available tools, you can use the interface to work with documents, images and generated content.

You can use BullsAI Chat to summarize uploaded materials, extract or interpret information from images, generate images from text prompts, and experiment with different approaches to research, writing, coding and analysis.

The models in BullsAI Chat are open-weight large language models. These are AI systems whose model weights have been made available for others to run, adapt or deploy under the model’s license terms.

Open-weight models can be competitive with commercial AI chatbots for many everyday tasks, though performance varies by model, prompt and use case. Some models may be better for writing, others for coding, reasoning, summarization, multilingual work or image-related tasks.

BullsAI Chat is powered by Open WebUI, an open-source interface for working with AI models. Open WebUI provides the chat experience, model selector and many of the interaction features used in BullsAI Chat.
