Researchers have developed CanonQ, a novel framework for extreme low-bit quantization of large language models (LLMs). This method addresses the challenges of simultaneously quantizing weights, activations, and KV caches by employing a unified quantization-aware training approach. CanonQ separates source canonicalization from task-aware adaptation, using fixed rotations and energy normalization to map diverse tensor sources to canonical coordinates. This allows for the reuse of frozen Gaussian-reference codebooks across different layers and models, with joint training adapting the network to coupled quantization errors. The framework demonstrates significant improvements, particularly under W2A4KV2 compression, achieving better perplexity and accuracy on LLaMA3 models compared to state-of-the-art baselines. Its benefits also extend to other models like Qwen3-1.7B and instruction-tuned MobileLLM-Pro-1B, showing substantial gains in code generation and mathematical reasoning tasks. AI
