FAQs

1 Is using a local AI model free?

Yes. With iBoomto AI, you can install a local model on Windows and run them for free.

2 Is my data private when using local model?

Yes. Everything runs locally - your files and prompts never leave your machine. There’s no telemetry sent to our servers about what you’re running or what you’re saying to the model.

3 Do local models need an internet connection?

You only need an internet connection when downloading the model for the first time; no connection is required for subsequent chatting.

4 How to choose the right AI Model as a beginner?

We highly suggest starting with a lightweight model that is compatible with your PC. This category of models generally has under 4B parameters, a file size of 1 - 4 GB, and can run on a CPU with 8 GB RAM, no GPU needed.

5 What’s the difference between a 4B and a 27B model?

The number refers to the number of parameters (weights) in the model. Generally, models with more parameters can handle complex tasks better, provide more detailed responses, and offer stronger reasoning capabilities. However, they also require more RAM and may run more slowly.
