almostrobot/gpt4all ? reverse-engineered prompt

Build me a desktop app for chatting with open source AI models that run locally on a normal computer, even without internet once the model is downloaded. I want a simple chat experience where I can pick a model, download it, ask questions, and keep the conversation going on my CPU or GPU if available. It should work with the newer GGUF model files, and make it clear which models are available and how much storage they need.

Also include a small local API so other apps can send prompts to the model, and basic support for using the same core model runner from a few common languages if that fits naturally. Keep everything focused on privacy, local use, and easy setup. If you need to check current model or build docs online, go ahead and do that.
