Smaller than WinRaR but 4x faster - Compresses 4-6x faster than WinRaR while being smaller

by
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 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

How did Astra change the scope or ambition of what you built?

Astra did 98%+ of the coding and heavily optimized it from scratch, I would say 1B+ tokens were used
