Our compressed outputs are smaller than WinRaR m5 (highest tier) while being 4-6 faster and using up to 15x less ram during compression, the EXE will be released at 5am UTC September 19, the compressor is currently available online at https://noethix.com/compression we benchmarked it by CPU seconds it takes to compress, both ran on single thread We used GPT-6 Astra to heavily optimize it I would guess about 1B+ tokens were used

Could you build this?
No Creating a lossless data compression algorithm that beats WinRAR m5 compression ratio while running 4-6x faster with 15x less memory represents cutting-edge information theory and low-level algorithmic research.
What it would actually take: Developing novel compression codecs of this tier requires deep expertise in information theory, entropy coding (rANS, tANS, arithmetic coding), advanced dictionary matching (LZ77/LZMA variants), and assembly-level SIMD optimizations (AVX-512/NEON). Building such an engine requires years of low-level Systems/C/Rust engineering and academic-level algorithmic breakthroughs, well beyond the capability of AI vibecoding.
