Researchers have developed a novel quantization technique called Tied Trit-Planes (PTQTP) that constrains LLM weight matrices to a uniform nine-level quantizer. This method allows for a lossless folding of two trit planes into a single 4-bit code plane, which serves as the persistent representation for disk-streaming Mixture-of-Experts models. Applied to DeepSeek-V4-Flash-0731, this approach resulted in smaller file sizes, faster decoding, and comparable or improved performance on benchmarks like MMLU compared to a 4.5-bit baseline, despite showing higher weight-reconstruction error.
