| # Sipsa Labs |
|
|
| Sipsa Labs builds SIP, the operating system for the physical world. |
|
|
| UltraCompress is retired. Its public materials preserve historical research; new API access and paid pilots are no longer offered. |
|
|
| The research results below are historical and apply to their recorded versions and evaluation conditions. |

|
| ## Historical UltraCompress research |
|
|
| **Historical research tiers:** |
|
|
| - A **genuinely lossless archival tier** — reconstructs the original weights bit-for-bit (~1.3–1.6× smaller) for exact storage and hand-off. |
| - A **near-lossless 5-bit tier** — ~1% perplexity vs bf16 (lossy), ~3× smaller, for running frontier-scale models on small GPUs. |
|
|
| **23 architectures verified**: 22 PPL-verified end-to-end (21 transformer — 17 dense + 4 MoE — plus 1 SSM with a comparator-note caveat) and 1 Vision Transformer cosine-verified (DINOv2-Large). Dense + MoE + SSM + ViT, 0.6B to 405B. The public v0.6.27 CLI checks basic pack structure and computes SHA-256 fingerprints unless hashing is skipped. It does not reconstruct weights, reproduce the evaluations below, or automatically compare its fingerprint with a trusted reference. |
|
|
| ### Verified 5-bit PPL ratios (sample) |
|
|
| *(perplexity ratio = compressed PPL / bf16 baseline PPL; FineWeb-edu held-out tail; seq_len = 1024; n = 30–50; seed = 42)* |
|
|
| | Model | Params | Type | PPL ratio | Notes | |
| |---|---:|:---|---:|:---| |
| | **Mixtral-8x7B** | 47B | MoE | **1.00368×** | tightest MoE result | |
| | Qwen3-1.7B-Base | 1.7B | dense | **1.00401×** | small-decoder record | |
| | Qwen3-14B | 14B | dense | **1.00403×** | 14B-class record | |
| | Yi-1.5-9B | 8.8B | dense | **1.00414×** | >8B record | |
| | Qwen3-8B | 8B | dense | **1.00440×** | 8B-class record | |
| | Mistral-7B-v0.3 | 7B | dense | **1.00548×** | strong dense 7B-class result | |
| | Phi-3-mini-4k | 3.8B | dense | **1.00262×** | tightest dense ratio (seq_len=128 caveat) | |
| | **Hermes-3-Llama-3.1-405B** | 405B | dense | **1.0066×** | 405B-class near-lossless on a single 32 GB GPU (streamed from disk) | |
| | Mamba-2.8B | 2.8B | SSM | **1.0059×** | state-space model — SSM-compatible comparator (the canonical transformer pipeline is architecture-incompatible with SSMs) | |
| | Llama-3.1-8B | 8B | dense | **1.0125×** | honest worst case (pipeline-specific floor, not architectural) | |

| |
| ### Inspect a historical pack |
| |
| ```bash |
| pip install ultracompress |
| hf download SipsaLabs/qwen3-1.7b-base-uc-v3-bpw5 --local-dir ./pack |
| uc verify ./pack |
| ``` |
| |
| Expected result category: basic pack-structure checks and a computed fingerprint, not a reconstruction proof or an automatic comparison with a trusted reference. |
| |
| Without an API key, `uc try` prints a recorded reference response, not a live inference result. |
