AI-native lossless compression — up to 86% smaller, 186× faster than zstd, SHA‑256 verified. Drop-in replacement for gzip and zstd.
gzip, zstd, and Brotli are all built on the same idea: find repeated byte sequences and replace them with shorter references. They have no concept of what your data means.
A transformer-based neural model can predict the next byte in a log file, a JSON response, or a legal document with far greater accuracy than any pattern-matching heuristic. That predictive power directly translates to fewer bits — approaching the theoretical information limit.
AhanaZip’s neural model understands the structure of your data. The more repetitive and semantic the content, the bigger the gains.
All benchmarks run on standard corpora with published methodology. Every result includes full parameter logs. SHA-256 hash of every compressed file verified on decompress.
† Measured on enwik8 (10 MB) Wikipedia corpus. AhanaZip Lossless mode vs zstd-22, Brotli-11, gzip-9 at maximum compression level. All methods strictly lossless. SHA-256 verified on every result. Full methodology at api.ahanazip.com/docs/benchmarks.
Fine-tuned on domain corpora, specialist models push compression ratios dramatically higher on structured data. The same base model, specialized in 5,000–8,000 training steps.
AhanaZip closes fundamental capability gaps that gzip, Brotli, and zstd have never addressed.

Real benchmark numbers — enwik8-64MB Wikipedia corpus, same hardware. Ratio panel shows AhanaZip Lossless vs competitors at max compression. Speed panel shows AhanaZip's three lossless modes — all produce bit-perfect SHA-256 verified output.
* enwik8 (10 MB) Wikipedia corpus, 24-core machine. Ratio: AhanaZip Lossless (best-ratio mode) vs codecs at max compression, all lossless. Speed: AhanaZip Turbo and Fast modes vs gzip-9 and zstd-22 at max compression (~3 MB/s). All AhanaZip modes produce bit-perfect output with SHA-256 integrity verification. Specialist domain models achieve higher ratios on structured corpora (scientific, medical, financial).

AhanaZip mirrors the API surface of gzip and zstd. Replace your current compressor in one line. The REST API accepts binary and returns binary — language agnostic.
compress(data) / decompress(data) — that's it.# Before — standard zstd import zstandard as zstd cctx = zstd.ZstdCompressor(level=22) compressed = cctx.compress(data) # After — AhanaZip (one line change) import ahanazip as zstd cctx = zstd.Compressor() compressed = cctx.compress(data) # REST API (any language) import requests resp = requests.post( "https://api.ahanazip.com/v1/compress", headers={"X-API-Key": api_key}, data=open("archive.log", "rb") ) compressed = resp.content # .aarm bytes # Verify lossless integrity original = ahanazip.decompress(compressed) # SHA-256 checked automatically ✓
At scale, compression ratio is money. A 17-point improvement over zstd doesn't sound like much until you're storing petabytes.
