cuda.bindings Support Policy

The cuda.bindings module has the following support policy:

1. The module shares the same major.minor version with the CUDA Toolkit. The patch version (the third number in the version string), however, is reserved to reflect Python-only changes and is out of sync with the Toolkit patch version.

2. The module is actively maintained to support the latest CUDA major version and its prior major version. For example, as of writing the bindings for CUDA 11 & 12 are maintained. Any fix in the latest bindings would be backported to the prior major version.

3. The module supports CUDA minor version compatibility, meaning that cuda.bindings 12.x supports any Toolkit 12.y. (Whether or not a binding API would actually correctly function depends on the underlying driver and the Toolkit versions, as described in the compatibility documentation.)

4. The module supports all Python versions following the CPython EOL schedule. As of writing Python 3.9 - 3.13 are supported.

5. The module exposes a Cython layer from which types and functions could be cimport’d. While we strive to keep this layer stable, due to Cython limitations a new minor release of this module could require Cython layer users to rebuild their projects and update their pinning to this module.

The NVIDIA CUDA Python team reserves rights to amend the above support policy. Any major changes, however, will be announced to the users in advance.
