Start your journey with Private LLM today and elevate your productivity and creative projects with the most private AI assistant for iOS devices. Private LLM is a better alternative to generic llama.cpp and MLX wrappers apps like Enchanted, Ollama, LLM Farm, LM Studio, Locally AI, RecurseChat, etc on three fronts: 1. Private LLM uses a faster and highly-optimized mlc-llm based inference engine. 2. Models in Private LLM are quantized using the state of the art quantization algorithms like OmniQuant, while competing apps use naive round-to-nearest quantization. 3. Private LLM is a fully native app built using C++, Metal and Swift with deep integrations with iOS and iPadOS, while many of the competing apps are bloated and non-native Electron or Flutter based apps. Please note that Private LLM only supports inference with text based LLMs. Model support varies by device capabilities.

I have the same issue someone else had. Eventually then LLMs start delivering gibberish and I have to restart. Too bad. Good idea, but too many issues.

Developer Response
Thanks for the feedback. Private LLM runs LLM inference fully on-device, so results depend on the model you pick and how much free memory your device has. If the device runs low on RAM - or if a chat grows past the model’s context window - responses can degrade and look like gibberish. On iPhone, background apps that hog memory and Low Power Mode can also impact quality.Close background apps and avoid Low Power Mode while generating. If a chat gets very long, start a new one to keep within the model’s context window. You can see available free memory at the bottom of the Help screen in the app.If you’d like, please join our Discord and we’ll help you choose the right model and settings for your device.

Only gives gibberish answers

While the app technically does allow you to run models locally on your device, I can’t find a single model, including the packaged one, that gives even remotely accurate answers to simple questions. The answers are always gibberish. This is on a 16pro, so if it’s a limitation of my device, I’m not sure which one would do any better. Tweaking the model parameters doesn’t help at all.

What model is this with? We support hundreds of models at this point.
