ultracompress
Last released
Near-lossless 5-bit transformer compression (~1% perplexity vs the bf16 reference; lossy), with reproducible, cryptographically verifiable reconstruction — 22 PPL-verified architectures (17 dense + 4 MoE + 1 SSM) plus 1 ViT cosine-verified — across 4 architecture classes (0.6B–405B). Public CLI does pack structure + download-integrity checks; the codec is patent-pending and not distributed. BUSL-1.1 + Additional Use Grant.
