openvino_genai_windows 0.1.0

Windows x64 implementation of openvino_genai. Downloads the pinned Intel OpenVINO GenAI runtime (SHA-256 verified), compiles the C bridge and bundles the DLLs.

openvino_genai_windows

The Windows x64 implementation for openvino_genai. Apps should not depend on this package directly — depend on openvino_genai and this one comes along automatically.

What it does at build time

When a Flutter Windows app that (transitively) depends on this package is built, this package's windows/CMakeLists.txt:

1. Downloads the pinned official OpenVINO GenAI runtime archive from storage.openvinotoolkit.org — ~233 MB, verified against a pinned SHA-256, cached under %LOCALAPPDATA%\openvino_genai_dart so it downloads once per machine, not per build.
2. Compiles the C bridge (openvino_genai_bridge.dll) from source against that exact archive's headers and import libraries, so the bridge and the runtime can never be version-skewed.
3. Bundles the runtime DLL set next to your .exe via Flutter's standard plugin bundling.

Runtime pin

Package version	OpenVINO GenAI runtime	Archive SHA-256
0.1.x	2026.0.0.0	8a6a75eb…beb1fb

One release, one pin. If your app also uses OpenVINO through another channel, make sure only ONE copy of the runtime DLL set ends up in the process.

Offline / proxy-restricted builds

Pre-download the archive (any machine), then point the build at it:

set OPENVINO_GENAI_ARCHIVE=C:\downloads\openvino_genai_windows_2026.0.0.0_x86_64.zip
flutter build windows

OPENVINO_GENAI_CACHE_DIR redirects the cache directory. Both are also available as CMake -D variables.

What gets bundled

The field-trimmed Release set (~130 MB): core runtime + GenAI + C API + tokenizers (with ICU), the CPU/GPU/NPU device plugins, AUTO/HETERO/BATCH plugins, the IR frontend, and Release TBB.

Not bundled by default: the NPU compiler (72 MB — the NPU plugin alone cannot compile models for the NPU) and the ONNX/TensorFlow/TFLite/ PyTorch/Paddle frontends (OpenVINO IR models don't need them). Building with OPENVINO_GENAI_BUNDLE_FULL=ON restores all of them.

Licensing

This package is Apache-2.0. The OpenVINO runtime it downloads and bundles is © Intel Corporation, licensed Apache-2.0; the files bundled beside your app are listed in Intel's redist.txt. The bundled tokenizers pull in ICU, whose license requires its notice to accompany redistributions (ICU-LICENSE). Copies of the relevant licenses and third-party notices ship in this package's third_party/ directory — ship them with your app (e.g. in your installer or an about screen).
