Where are the older NKI API reference pages?#

If you landed on this page, you probably followed a link to an older NKI API reference page. The NKI API reference documentation has been updated to match the NKI APIs that shipped with Beta 2 of the Neuron Kernel Interface in December 2025.

To view older versions of the NKI API docs, follow these steps:

  1. Go to the AWS Neuron docs home page: https://awsdocs-neuron.readthedocs-hosted.com/en/latest/

  2. Click on the version selector dropdown at the top left of the page (it will say latest by default).

  3. Select the version that corresponds to the older NKI API docs you want to view. The last published version of the NKI API docs before the Beta 2 release is version 2.26.1.
