## What Rocket 3B is good at

general

Rocket 3B is a small language model with 3 billion parameters, fine-tuned to follow instructions and chat. It performs well on conversation benchmarks, often matching or beating much larger models. The model is designed for generating detailed text responses but may produce unsafe outputs since it lacks built-in safety filters.

## Why run Rocket 3B in Private LLM

Private LLM has run local AI on iPhone, iPad, and Mac since 2023, before Apple Intelligence existed. Inference happens on your device, so your Rocket 3B conversations never reach a server. The part most apps gloss over is quantization, and that is exactly where on-device quality is won or lost. Most llama.cpp and MLX wrappers ship the same off-the-shelf 4-bit RTN weights. Private LLM ships GPTQ and OmniQuant quantization, tuned per model, and our 3-bit OmniQuant models match or beat those 4-bit RTN builds on the same Apple Silicon. Run the same model both ways and you feel it in the first reply. [See how our quantization works](/en/faq#Why-can-t-Private-LLM-load-models-directly-from-Hugging-Face).
