+# OpenStems Models
+
+Model resources for the OpenStems native C++ separation engine. CPU and NVIDIA editions use the same model weights. This release preserves the FP32 GGUF files used by OpenStems for Windows on 2026-09-21.
+
+## Download files
+
+Each ZIP contains one GGUF file. ZIP compression reduces download size without changing the model bytes or precision.
+
+| Model | Download | Extracted file | Extracted bytes |
+| --- | --- | --- | ---: |
+| T400 | [T400-478978733353.zip](T400-478978733353.zip) | T400.gguf | 270145408 |
+| B400 | [B400-aa162a2eca9f.zip](B400-aa162a2eca9f.zip) | B400.gguf | 206407520 |
+| BS Karaoke | [karaoke-4804181ac76c.zip](karaoke-4804181ac76c.zip) | karaoke.gguf | 204258848 |
+| BS SW | [sw-68bed29111b6.zip](sw-68bed29111b6.zip) | sw.gguf | 698768832 |
+
+[model-files.json](model-files.json) records the exact archive and extracted-file sizes and SHA-256 checksums. Separate `.sha256` files are also supplied. Installers should pin a repository commit and verify both the download and extracted model against the manifest.
+
+## Use
+
+The OpenStems installer downloads and verifies the required resources automatically. Fast uses T400, Pro uses B400, and Ultra selects the required Karaoke/SW recipe. These are model resources for the OpenStems native runtime; a `.gguf` extension alone does not guarantee compatibility with another runtime.
+
+The model files remain subject to their respective applicable upstream terms. Packaging and format conversion do not replace those terms or establish a new license for the weights.
+
+## 中文说明
+
+本仓库存放 OpenStems 原生 C++ 分离引擎使用的四个模型。CPU 与 NVIDIA 版本共用同一份权重，保留当前 FP32 GGUF 精度。ZIP 仅用于无损压缩下载，解压后的模型字节保持不变。安装器应使用固定提交版本，并按清单校验下载包及解压后的模型文件。
