Superior Model Performance With State-Of-The-Art Quantization

The core of Private LLM's superior model performance lies in its use of the state-of-the-art OmniQuant quantization algorithm. While quantizing LLMs for on-device inference, outlier values in LLM weights tend to have a marked adverse effect on text generation quality. Omniquant quantization handles outliers by employing an optimization based learnable weight clipping mechanism, which preserves the model's weight distribution with exceptional precision. RTN (Round to nearest) quantization used by popular open-source LLM inference frameworks and apps based on them, does not handle outlier values during quantization, which leads to inferior text generation quality. OmniQuant quantization paired with optimized model-specific Metal kernels, enables Private LLM to deliver text generation that is not only fast but also of the highest quality, significantly raising the bar for on-device LLMs.

Remarkably good app, very active developer
by Conventional Dog-Apr 7, 2024

Possibly the single best app purchase I've ever made. The developer is constantly improving it and talking with users on Discord and elsewhere. One price includes Mac, iPhone, and iPad versions (with family sharing). Mac shortcuts can be used to create what amount to custom GPTs. (There's even a user-contributed, quite clever bedtime story generator on the website.) The 10.7B-parameter SOLAR LLM (one of many included) running on my 16 GB M1 MacBook Air gives me fast responses that are subjectively almost on the level of GPT-3.5. For something running completely locally with full privacy, it's remarkable. More RAM allows an even larger choice of language models. But the tiniest model running on my iPhone 12 Pro is usable. (Tip: Experiment with changing the system prompt to fine-tune it for your purposes.)
