+### Qwen4-27B NVFP4 — preparation stage
+
+We are preparing a reproducible NVFP4 quantization and release workflow for the anticipated Qwen4-27B model. The toolkit, CI, artifact checks, and release checklist are available on GitHub.
+
+**Current status: preparation only.** No Qwen4 model weights, benchmark results, or validated Qwen4 architecture compatibility are available yet. Any future HF checkpoint release requires confirmation of the official source and license, GPU inference tests, and quality evaluation. This is an independent community project, not affiliated with Qwen or NVIDIA.
