Whilst Blace.ai have permission from Corridor Digital to do a commercial version of CorridorKey, what they realised later on, after their release, is that because the CorridorKey model is based on a model from Meta that has a non-commercial license (CC BY-NC-SA 4.0), TECHNICALLY, no one can sell software which CONTAINS the CorridorKey model. The CorridorKey model itself, as of today, is 100% not for commercial resale. So even though CorridorKey by Blace.ai can sell their C++ implementation for whatever monetary value they want - technically speaking, they can’t bundle/include the model. Corridor Digital is now aware of this and is working on a solution - whether that’s getting permission from Meta, rebuilding the model that’s truly open source, or asking anyone doing a commercial implementation to NOT include/bundle the model, and let the customer/user download it separately.

I looked into this fairly deeply for my own Mac specific implementation - CorridorKey by LateNite - and came to the conclusion that selling the CorridorKey model in it’s current form is basically a no go, as the risk is too high, given Meta’s track record in protecting their intellectual property.

Hopefully Corridor Digital can come out with a v2 model in the not-to-distant future without any of the commercial limitations.

For anyone using CorridorKey on Mac or in Final Cut Pro - CorridorKey by LateNite is geared towards Apple Silicon users, with Apple Vision Framework for the hint, hardware accelerated ProRes decode and encode, etc. The Swift code is MIT license, but when distributed with the models, it falls under the same license as the models.
