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.
