Could you build this?
No Developing viable 1-bit quantized LLMs requires cutting-edge machine learning research, custom low-bit GPU/CPU inference kernels, and specialized training pipelines.
What it would actually take: This project requires novel Quantization-Aware Training (QAT) algorithms (e.g., BitNet-style 1.58-bit architectures), specialized matrix multiplication kernels written in CUDA/Triton/C++ using bit-manipulation instructions, and millions of GPU hours for pre-training or fine-tuning. It requires a dedicated team of ML researchers and kernel engineers.
