PAQ8PX – Experimental Lossless Data Compressor & Entropy Estimator

AI-powered text compression library for RAG systems and API calls. Reduce token usage by up to 50-60% while preserving semantic meaning with advanced compression strategies.

Code and data for VTCBench, a VLM benchmark for long-context understanding capabilities under vision-text compression paradigm.

Offline Dictionary-based Compression (Re-Pair, Recursive Pairing)

LLMA = LLM + Arithmetic coder, which use LLM to do insane text data compression. LLMA=大模型+算术编码，它能使用LLM对文本数据进行暴力的压缩，达到极高的压缩率。

Extreme inline text compression for HTML / JS. A custom pipeline that generates stand-alone HTML or JS files which embed competitively compressed self-extracting text, with file sizes of 25% - 40% the original.

Reverse T9 for LLMs. Free, open-source prompt compressor for your AI prompts and agents.
