LittleBit achieves sub-1-bit LLM compression via latent factorization
October 8, 2026
LittleBit compresses dense weight matrices into the 0.1 bits-per-weight regime by factorizing weights into low-rank latent factors and applying binarization. The LittleBit-2 update utilizes Joint Iterative Quantization to align SVD-derived factors with the binary hypercube, improving accuracy without increasing inference overhead.
