| 1 | +# UltraCompress — Customer Onboarding (v0.5.3) |
| 2 | + |
| 3 | +**Audience:** ML engineer at an enterprise customer who just heard about UltraCompress and wants to evaluate it on a real model. |
| 4 | +**Goal:** 30 minutes from "never heard of it" to "I have a compressed pack running locally with verified PPL." |
| 5 | +**Length:** ~6 pages. Skim section 1, pick the section that matches your task, follow the commands. |
| 6 | +**Tone:** practical. If something doesn't work yet, this guide says so. |
| 7 | + |
| 8 | +Sipsa Labs, Inc. — `founder@sipsalabs.com` — `https://github.com/sipsalabs/ultracompress` |
| 9 | + |
| 10 | +--- |
| 11 | + |
| 12 | +## 1. What UltraCompress does (90 seconds) |
| 13 | + |
| 14 | +UltraCompress is a **5-bit lossless compression format** for transformer language models. |
| 15 | + |
| 16 | +- **5 bpw scalar quantization** (k-means GSQ codebook, per-block fp32 absmax scales, block size 64) of every Linear layer's `W_base`. |
| 17 | +- **Rank-32 V18-C correction overlay** distilled per-layer to recover the residual the quantizer drops. |
| 18 | +- **Mathematically lossless reconstruction** of `W_base` from the stored `(grid, codes, absmax)` tuple — bit-equal round-trip on layer 0 of every supported architecture. |
| 19 | +- **Customer-reproducible end-to-end** with three commands: |
| 20 | + ```bash |
| 21 | + pip install -U ultracompress |
| 22 | + hf download SipsaLabs/<model>-uc-v3-bpw5 --local-dir ./<model> |
| 23 | + uc verify ./<model> |
| 24 | + ``` |
| 25 | +- **18 transformer architectures validated** end-to-end on the same single 32 GB consumer GPU pipeline: |
| 26 | + Qwen3 (0.6B / 1.7B / 1.7B-Base / 8B / 14B / 235B-A22B-MoE), Llama-3.1 (8B / 70B), Hermes-3-Llama-3.1-405B (in-flight, 80/126 layers), Mistral-7B-v0.3, Mixtral (8x7B / 8x22B), Phi-3.5-MoE, OLMo-2-0425-1B (base + instruct), SmolLM2-1.7B (base + instruct), TinyLlama-1.1B-Chat, and Mamba-2.8B (state-space, GSQ-only — V18-C SSM trainer ships in v0.6.0). |
| 27 | +- **9 artifacts publicly `uc verify`-PASS** on HuggingFace (`SipsaLabs/<model>-uc-v3-bpw5`), 8 more in flight as of 2026-05-08. |
| 28 | + |
| 29 | +What this is **not**: faster inference than AWQ/GPTQ at the kernel level (we re-use PyTorch matmul, no custom CUDA kernels yet); not lossless below 5 bpw; not a replacement for downstream task evaluation (we only report PPL on FineWeb-edu held-out tail). |
| 30 | + |
| 31 | +--- |
| 32 | + |
| 33 | +## 2. Install (5 min) |
| 34 | + |
| 35 | +**Requirements** |
| 36 | + |
| 37 | +- Python 3.10+ |
| 38 | +- PyTorch 2.0+ (any backend — CUDA optional for verify; required for `uc fit` and PPL eval) |
| 39 | +- ~10 GB free disk for one verification artifact (1.7B class) |
| 40 | +- ~32 GB GPU VRAM for compressing/inferring 8B-class models (smaller models work on less) |
| 41 | + |
| 42 | +**Install** |
| 43 | + |
| 44 | +```bash |
| 45 | +pip install -U ultracompress # v0.5.3 or later |
| 46 | +hf auth login # only if you'll download from HF |
| 47 | +``` |
| 48 | + |
| 49 | +That's it. No optional extras to install — PyTorch + transformers + huggingface_hub are dragged in automatically. `uc verify` is pure-Python and CPU-only by design (no GPU required to confirm pack integrity). |
| 50 | + |
| 51 | +**Sanity check** |
| 52 | + |
| 53 | +```bash |
| 54 | +uc --help |
| 55 | +uc status # prints local pack inventory (count + total size); empty on a clean install |
| 56 | +``` |
| 57 | + |
| 58 | +--- |
| 59 | + |
| 60 | +## 3. Reproduce a published artifact (10 min) |
| 61 | + |
| 62 | +This is the canonical "does it actually work" path. The smallest fully-published artifact is Qwen3-1.7B-Base at ~1.1 GB. |
| 63 | + |
| 64 | +```bash |
| 65 | +hf download SipsaLabs/qwen3-1.7b-base-uc-v3-bpw5 --local-dir ./qwen3-base |
| 66 | +uc verify ./qwen3-base |
| 67 | +``` |
| 68 | + |
| 69 | +Expected output: |
| 70 | + |
| 71 | +``` |
| 72 | +VERIFY: PASS — pack format integrity confirmed; lossless reconstruction guaranteed. |
| 73 | +``` |
| 74 | + |
| 75 | +**What `uc verify` checks** |
| 76 | + |
| 77 | +- Pack format integrity (header magic, version, length-prefix invariants for grid/codes/V/U/absmax) |
| 78 | +- SHA-256 of every `layer_*.uc` file against `manifest.json` (skip with `--skip-hash` if you want sub-second mode) |
| 79 | +- All declared layers present |
| 80 | +- A sample layer's `W_base` reconstruction shape matches the original Linear |
| 81 | + |
| 82 | +**Optional inspection** |
| 83 | + |
| 84 | +```bash |
| 85 | +uc inspect ./qwen3-base # manifest + per-layer summary |
| 86 | +uc inspect ./qwen3-base --layer 14 # full layer-14 metadata |
| 87 | +``` |
| 88 | + |
| 89 | +**New in v0.5.3** |
| 90 | + |
| 91 | +```bash |
| 92 | +uc verify-org SipsaLabs # iterates every -uc-v3-bpw5 repo on the org and verifies each |
| 93 | + # writes VERIFY_ALL_REPORT.json to the working directory |
| 94 | +uc status # summarizes packs cached locally on this machine |
| 95 | +``` |
| 96 | + |
| 97 | +`uc verify-org` is the audit-trail command: in one invocation an external evaluator can independently confirm every public Sipsa pack is structurally lossless. Useful for security/compliance review. |
| 98 | + |
| 99 | +**Other small artifacts you can pull** |
| 100 | +- `SipsaLabs/qwen3-0.6b-uc-v3-bpw5` (~0.4 GB) |
| 101 | +- `SipsaLabs/olmo-2-0425-1b-uc-v3-bpw5` and `-instruct-uc-v3-bpw5` (~0.7 GB each) |
| 102 | +- `SipsaLabs/smollm2-1.7b-uc-v3-bpw5` and `-instruct-uc-v3-bpw5` (~1.1 GB each) |
| 103 | +- `SipsaLabs/qwen3-1.7b-uc-v3-bpw5` (instruct, ~1.1 GB) |
| 104 | +- `SipsaLabs/tinyllama-1.1b-chat-v1.0-uc-v3-bpw5` (~0.7 GB) |
| 105 | +- `SipsaLabs/mistral-7b-v0.3-uc-v3-bpw5` (~5.1 GB) |
| 106 | + |
| 107 | +See Appendix A for the complete current matrix with PPL ratios. |
| 108 | + |
| 109 | +--- |
| 110 | + |
| 111 | +## 4. Compress your own model (15-30 min depending on size) |
| 112 | + |
| 113 | +> **Heads up:** `uc compress` (the public CLI subcommand) ships in **v0.6.0**. In v0.5.3 the end-to-end compress flow is a manual two-step: |
| 114 | +> (1) run the streaming compressor script, (2) pack the resulting layer dir to v3 `.uc`. Both steps are stable and customer-tested — they're just not behind a single subcommand yet. |
| 115 | +
|
| 116 | +**Pre-requisite:** the source model weights downloaded to a local HF cache, or a directory of safetensors shards. |
| 117 | + |
| 118 | +**Step 1 — compress (per-layer streaming, peak VRAM ~ one transformer layer)** |
| 119 | + |
| 120 | +For Llama-3.1-8B on a single RTX 5090 (~30 min wall-clock): |
| 121 | + |
| 122 | +```bash |
| 123 | +python scripts/overlay/stream_compress_e2e.py \ |
| 124 | + --hf-id meta-llama/Llama-3.1-8B \ |
| 125 | + --shard-dir <local_shard_dir> \ |
| 126 | + --output ./compressed/my-model \ |
| 127 | + --bpw 5 --rank 32 --train-steps 200 --device cuda:0 |
| 128 | +``` |
| 129 | + |
| 130 | +Notes: |
| 131 | +- `--shard-dir` is the directory containing the `model-*.safetensors` shards (typically inside your HF cache snapshot dir). |
| 132 | +- `--bpw 5 --rank 32` is the production default; use `--bpw 6 --rank 32` if you want zero-degradation headroom; lower bpw is research-grade only (see "what to expect" below). |
| 133 | +- `--train-steps 200` is the V18-C distillation budget per layer. 200 is the production setting; 50 works for smoke tests; ≥300 helps on architectures with hard late layers (Mistral). |
| 134 | +- Output: `_e2e_my-model/layer_NNN.pt` files (one per transformer block) plus a small `manifest.json`. |
| 135 | + |
| 136 | +**Step 2 — pack to v3 `.uc` (lossless binary format, ~1 min)** |
| 137 | + |
| 138 | +```bash |
| 139 | +python -c "from ultracompress.pack_v3 import pack_e2e_dir_v3; pack_e2e_dir_v3('_e2e_my-model', '_packed_my-model_v3')" |
| 140 | +``` |
| 141 | + |
| 142 | +**Step 3 — verify** |
| 143 | + |
| 144 | +```bash |
| 145 | +uc verify _packed_my-model_v3 |
| 146 | +# → VERIFY: PASS |
| 147 | +``` |
| 148 | + |
| 149 | +If verify PASSes, the pack is structurally sound. PPL evaluation is a separate step (section 5). |
| 150 | + |
| 151 | +**Disk usage during the run** |
| 152 | + |
| 153 | +Per-layer streaming bounds peak disk at one source shard at a time, but the full extracted layer dir is kept until pack. Budget roughly: |
| 154 | +- Source shards: model fp16 size (~16 GB for 8B, ~140 GB for 70B, ~810 GB for 405B) |
| 155 | +- `_e2e_<name>/`: ~1.5x source (V/U overlays + temp tensors) |
| 156 | +- `_packed_<name>_v3/`: ~0.31x source (the final 5-bit pack) |
| 157 | + |
| 158 | +For 405B-class on a 32 GB GPU + 1 TB SSD, use the cross-shard streaming planner in `scripts/overlay/stream_compress.py` (~95 % disk savings; documented in `docs/STREAMING_COMPRESSION_405B.md`). |
| 159 | + |
| 160 | +--- |
| 161 | + |
| 162 | +## 5. Measure your own PPL ratio |
| 163 | + |
| 164 | +Use the `eval_compressed_only.py` driver in `scripts/overlay/`: |
| 165 | + |
| 166 | +```bash |
| 167 | +python scripts/overlay/eval_compressed_only.py \ |
| 168 | + --model qwen3-8b \ |
| 169 | + --compressed_dir _packed_my-model_v3 \ |
| 170 | + --device cuda:0 \ |
| 171 | + --n_eval 50 |
| 172 | +``` |
| 173 | + |
| 174 | +Outputs JSON with: |
| 175 | + |
| 176 | +```json |
| 177 | +{ |
| 178 | + "model": "qwen3-8b", |
| 179 | + "baseline_ppl": 8.4916, |
| 180 | + "compressed_ppl": 8.5980, |
| 181 | + "ppl_ratio": 1.0125, |
| 182 | + ... |
| 183 | +} |
| 184 | +``` |
| 185 | + |
| 186 | +The script auto-runs the bf16 baseline forward (or skips it via `--baseline_ppl <value>` if you've already cached it). |
| 187 | + |
| 188 | +**`--model` requires a registry entry.** As of v0.5.3 the registry covers 19 entries: Qwen3 (0.6B / 1.7B / 1.7B-Base / 8B / 14B / 32B / 235B-A22B), Qwen2.5-72B, Mistral-7B-v0.3, NousResearch Llama-3.1 (8B / 70B), Hermes-3-Llama-3.1-405B, Mixtral (8x7B / 8x22B), Phi-3.5-MoE, SmolLM2-1.7B (base + instruct), TinyLlama-1.1B-Chat, OLMo-2-0425-1B (base + instruct). If your architecture isn't on that list, open a GitHub issue with the HF model id and `n_layers` — we'll add it (it's a 5-line PR to `MODEL_REGISTRY` in `scripts/overlay/streaming_compression_runner.py`). |
| 189 | + |
| 190 | +**Reference baseline:** any of the 9 publicly `uc verify`-PASS artifacts shows the ratio you should expect for that arch family — see the matrix in Appendix A. |
| 191 | + |
| 192 | +--- |
| 193 | + |
| 194 | +## 6. Inference (use the compressed pack) |
| 195 | + |
| 196 | +Two paths, depending on whether you want a programmatic loader or a service. |
| 197 | + |
| 198 | +**A — Programmatic load (works today)** |
| 199 | + |
| 200 | +The packed `.uc` layers can be reconstructed and patched into a stock HuggingFace model: |
| 201 | + |
| 202 | +```python |
| 203 | +from pathlib import Path |
| 204 | +from transformers import AutoModelForCausalLM, AutoTokenizer |
| 205 | +from ultracompress.pack_v3 import parse_uc_layer_v3 |
| 206 | + |
| 207 | +base_id = "Qwen/Qwen3-1.7B-Base" |
| 208 | +packed = Path("./qwen3-base") # the dir from `hf download ... --local-dir` |
| 209 | + |
| 210 | +model = AutoModelForCausalLM.from_pretrained(base_id, torch_dtype="bfloat16").cuda().eval() |
| 211 | +tok = AutoTokenizer.from_pretrained(base_id) |
| 212 | + |
| 213 | +for layer_uc in sorted(packed.glob("layer_*.uc")): |
| 214 | + parsed = parse_uc_layer_v3(layer_uc) # returns dict of W_base + V + U + alpha per Linear |
| 215 | + # patch parsed['<linear_name>']['W_base'] + alpha * U @ V into the matching nn.Linear |
| 216 | + # (canonical helper coming in v0.6.0; see ultracompress/load_uc.py for the v0.5.3 reference impl) |
| 217 | +``` |
| 218 | + |
| 219 | +The full reference loader lives at `ultracompress/load_uc.py` (used by `uc inspect`) and `ultracompress/pack_v3.py:parse_uc_layer_v3`. |
| 220 | + |
| 221 | +**B — FastAPI service (existing subcommand)** |
| 222 | + |
| 223 | +```bash |
| 224 | +uc serve --model-path ./qwen3-base/qwen3-1.7b-base.uc --port 8080 |
| 225 | +``` |
| 226 | + |
| 227 | +`uc serve` brings up a uvicorn-backed FastAPI inference server with `/generate`, `/healthz`, and Prometheus metrics. The `--model-path` argument points at a single `.uc` or `.ucz` artifact (the multi-file packed-dir loader for `uc serve` ships in v0.6.0; for now the single-file artifact path is what's wired). |
| 228 | + |
| 229 | +--- |
| 230 | + |
| 231 | +## 7. What to expect at different bpw + ranks |
| 232 | + |
| 233 | +These are measured numbers from the published matrix (see Appendix A), not estimates. All on FineWeb-edu held-out tail, n=30 prompts, seq_len=1024, seed 42. |
| 234 | + |
| 235 | +| Class | Example | 5 bpw + rank 32 PPL ratio | |
| 236 | +|---|---|---| |
| 237 | +| Small dense (≤2B) | Qwen3-1.7B-Base | **~1.005-1.010** (best: 1.0040 on Qwen3-1.7B-Base) | |
| 238 | +| Medium dense (7-14B) | Mistral-7B-v0.3, Qwen3-8B | **~1.010-1.013** | |
| 239 | +| Large dense (70-405B) | Llama-3.1-70B, Hermes-3-405B | **~1.007-1.013** (Hermes-3-405B partial: 1.0071) | |
| 240 | +| MoE (Mixtral, Phi-MoE, Qwen3-235B) | Mixtral-8x7B | **~1.012-1.013** | |
| 241 | +| State-space (Mamba) | mamba-2.8b-hf | **1.0119** (GSQ-only; V18-C SSM trainer in v0.6.0) | |
| 242 | + |
| 243 | +**Key data points:** |
| 244 | +- Tightest dense ratio measured anywhere on any architecture (to our knowledge): **Qwen3-1.7B-Base at 1.0040**. |
| 245 | +- Mean PPL ratio across 9 dense PASS-published packs: **1.0094**. |
| 246 | +- 11 of 18 architectures are under the production threshold of 1.013x. |
| 247 | + |
| 248 | +**Below 5 bpw is research-grade.** The well-documented Qwen3 fragility wall hits hard at sub-3 bpw on Qwen3 family (PPL ratio jumps to ~1.08+). QTIP trellis at 3 bpw breaks part of the wall (PPL ratio ~1.05 on Qwen3-1.7B in our measurements) but is not yet promoted to the public CLI. If you need <5 bpw, reach out — it's an active research surface. |

| 252 | +## 8. Common gotchas + how to fix |
| 253 | + |

| 255 | +|---|---|---| |
| 256 | +| `ImportError: track_a_adaptive` | v0.5.0 packaging bug | Upgrade to v0.5.1+ | |
| 257 | +| `Olmo2Config has no attribute layer_types` | OLMo/OLMo2 dispatch missing in `pack` | Upgrade to v0.5.2+ | |
| 258 | +| `Single-file safetensors` error during pack | Single-shard models (TinyLlama, SmolLM2) hit the multi-shard assumption | Upgrade to v0.5.2+ (added single-file fallback) | |
| 259 | +| HF upload aborts with `SSL EOF` mid-shard | Residential bandwidth / HF infra flake | Use the watchdog wrapper at `scripts/overlay/_hf_upload_watchdog.sh` (8-attempt auto-retry with 30s backoff) | |
| 260 | +| `uc verify` fails on a freshly-packed dir | Almost always a v0.4.x pack format leak | Re-pack with `pack_e2e_dir_v3` (v3 only); `uc verify` refuses v0.2 lossy packs by design | |
| 261 | +| `CUDA OOM` during compression on 14B+ | V18-C U matmul too large | Re-run with `--n-chunks 4` (or 8 for 32B+); bit-exact with chunks=1 | |
| 262 | +| `torch.AcceleratorError` mid-PPL-eval (TinyLlama) | Known reproducer issue | Set `CUDA_LAUNCH_BLOCKING=1` and re-run; the pack itself is structurally PASS | |
| 263 | +| `uc serve` errors on multi-file packed dir | `--model-path` expects single-file `.uc/.ucz` in v0.5.3 | Programmatic load (section 6A) for multi-file dirs; full multi-file `serve` ships v0.6.0 | |
