# Why change which LLM is used in the AI Assistant?

In Curiosity you can select which Large Language Model (LLM) is used in the app.

You can currently choose between:

• ChatGPT 3.5 (OpenAI)
• ChatGPT 4 (OpenAI, pro feature)
• Phi 2B (on-device, needs 2.5GB disk space, beta)
• Llama2 7B (on-device, needs 5GB disk space, beta)
• Llama2 13B (on-device, needs 10GB disk space, beta)
• Llama3 8B (on-device, needs 5GB disk space, beta)
• Mistral 7B (on-device, needs 5GB disk space, beta)
• MistralLite 7B (on-device, needs 5GB disk space, beta)

ChatGPT is a powerful online LLM system by OpenAI. Llama2 is an open-source LLM by Meta. The main differences are:

• ChatGPT is a large, cloud hosted model. That means it may perform better in some cases. However, it requires some data to be sent to OpenAI. Learn more here.
• Llama2 is run locally on your device. That means your data all stays local, but it means you have to download, store and run the model which requires a fast computer.

| Curiosity also supports custom models for enterprises in the context of your knowledge. Contact us to learn more.
