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.

• Chat history. Your conversations are now saved on device and kept in a new conversation list, with search that looks inside every chat, plus rename and delete.
• Conversations remember their model. Reopen a chat and Private LLM loads the model it was using - Llama, Gemma, Qwen, Mistral, Phi or DeepSeek R1 - automatically.
• Export any conversation to Markdown or PDF, from the chat or straight from the conversation list.
• Faster inference, with quicker model loading and switching.
• Still entirely yours: nothing leaves your device, and you can turn chat history off in Settings or delete every conversation at once.
• Siri and Shortcuts replies now reach the app that asked for them, instead of being dropped.
• Email Support now works even when Mail isn't set up - copy the address or the debug info, or open the support page instead.
• Accessibility improvements and a number of smaller fixes.
