Among the key changes in Nuke 15.0 software, there is built-in support for Apple Silicon processors, experimental support for the new open standard OpenAssetIO, and updates to the new 3D system. NukeX, the advanced version of the program, also received updates to the AIR machine learning framework, including the ability to distribute training sessions with CopyCat.
Nuke Studio, which includes editing capabilities, received updates that support a wider range of effects on the timeline.
In addition, Foundry released the open beta version of Nuke 14.1, a parallel release based on the CY2022 VFX Reference Platform specification, rather than the CY2023 specification used in Nuke 15.0. It has all the same new features, except for built-in Apple Silicon support.

Nuke 15.0 includes several updates to key technologies used in the workflow, including support for the current CY2023 VFX Reference Platform specification and USD 23.05. The release also introduces experimental support for OpenAssetIO, an open data exchange standard developed by Foundry for sharing data between DCC (Digital Content Creation) and asset management software, which was adopted by the Academy Software Foundation last year. The documentation states that the initial implementation is a "very basic technical preview" designed to allow studios to start testing OpenAssetIO in their workflows.
In addition to these changes, Nuke 15.0 features built-in support for Apple Silicon processors on modern Macs. This change makes Nuke the latest key application in VFX workflows to natively support M1 and M2 processors. Autodesk has already introduced support for Maya and Arnold, and SideFX for Houdini.
In release 15.0, the 3D compositing system based on USD, introduced in Nuke 14.0 last year, has been expanded. UI and workflow updates include a dedicated 3D toolbar in the viewer and two-level selection, such as selecting edges within an object, for more precise control.

The Scanline Render system and the GeoMerge node, used to combine stacks of objects into a single scene, have also been updated. The latter has gained five new merge modes aimed at giving users control over the data merging process when working with the new 3D system.
The USD implementation now supports USD Python bindings, allowing users to work with USD data directly through Python. Structural changes have been made to improve performance, simplify scene validation and filtering, and expand user capabilities in future export processes.

The AIR machine learning framework in Nuke has also been updated, enabling users to train their own neural networks for automating repetitive tasks like rotoscoping. Training times when using the CopyCat node have been reduced "by up to 50%", and key changes include the ability to distribute training across multiple machines.

Nuke Studio users have received support for the Inference node from AIR as a soft effect on the editing timeline. The update also includes access to more advanced Blink kernels as soft effects, including Denoise, LensDistortion, and blur effects. Network protocol support for NDI has been expanded, and sound support has been added when using NDI in Monitor Out.

Nuke 15.0 is currently in beta. The software is compatible with Windows 10 and higher, Rocky Linux 9, macOS 12.0 and higher, and it also natively supports Apple Silicon processors.

Nuke 14.1 is also in beta and is compatible with Windows 10 and higher, CentOS 7.4-7.6 Linux, and macOS 12.0 and higher. The software supports Apple Silicon through Rosetta emulation. To access the beta version, you need to have a license for Nuke, NukeX, or Nuke Studio with current maintenance. The beta period is expected to last until the end of the year.
