## Description

Grok-1 is an open-weights large language model implementation featuring a sparse mixture-of-experts architecture. It is designed for high-performance text generation and natural language processing by activating only a subset of specialized expert layers per token.

The model utilizes 8-bit weight quantization to reduce memory overhead and accelerate loading. To manage its high parameter count, the implementation supports activation sharding, which distributes the memory load across multiple hardware devices during execution.

The project covers large-scale model inference, including text completion generation and token sampling via nucleus sampling. It includes utilities for text sequence tokenization and the ability to initialize the model state using checkpoint-based weight loading.
