Diffusion LMs advance lossless text compression, beating LLMs and zstd

Researchers have introduced Diffusion Language Models (DLMs) as a novel approach to lossless text compression, aiming to overcome the throughput limitations of existing autoregressive LLM-based methods. This new framework, detailed in a recent arXiv paper, adapts DLMs for compression by addressing challenges related to symbol encoding decisions. Experimental results on the enwik8 benchmark indicate that the DLM-based framework achieves state-of-the-art compression ratios, surpassing traditional compressors like zstd and gzip, and also outperforming previous LLM-based compression techniques.

    Diffuse to Compress: Leveraging Diffusion LMs for Lossless Compression

    arXiv:2608.11249v1 Announce Type: cross Abstract: We study the problem of lossless text compression, motivated by the rapid growth in the collection and storage of digital textual data - including plain text, source code, and structured formats such as XML - and by recent advance…
