  <h1>🔌 88plug AI Lab</h1>
  <p class="subtitle">Production-grade compressed-tensors quantizations of frontier LLMs, VLMs, and omni models — engineered for native vLLM v0.9.0+ deployment.</p>
</div>

<h2>Why compressed-tensors</h2>
<p>Most quantization formats (AWQ, GPTQ, GGUF) target a single inference backend and ship a frozen weight layout that cannot be further composed or modified at load time. <code>compressed-tensors</code> is the format developed by Neural Magic and maintained as a first-class vLLM citizen.</p>
<ul>
  <li><strong>Native vLLM integration.</strong> No format conversion, no plugin shims. vLLM reads compressed-tensors models directly via its built-in <code>CompressedTensorsWorker</code>. Full PagedAttention, continuous batching, and tensor parallelism work without modification.</li>
  <li><strong>Composable precision.</strong> A single checkpoint can carry per-layer or per-group precision assignments. Mixed-precision MoE configurations are expressed in the same file.</li>
  <li><strong>Reproducible calibration metadata.</strong> The quantization config, calibration scheme, and per-channel scales are stored inside the checkpoint.</li>
  <li><strong>Forward compatibility.</strong> As vLLM adds new kernel support (FP8, INT8, sparse), compressed-tensors models gain that support without re-quantizing.</li>
</ul>
<p>AWQ and GPTQ remain fine for llama.cpp and older toolchains. If you are deploying on vLLM in production, compressed-tensors is the correct choice.</p>

  </div>
</div>
<p style="color:var(--muted);font-size:0.875rem">AutoRound at iters=200 runs sign-gradient optimization over a calibration set to minimize weight rounding error. At W4A16, this closes most of the gap between naive round-to-nearest and GPTQ/AWQ, while producing a checkpoint that vLLM can load natively.</p>
