If a AI model isn’t in the GUI, then the developers don’t intend you to use it. Since Proteus V4 isn’t in the GUI, they don’t intend you to use it.
As for what Proteus V4 offers, the details have been provided for Beta testers and here are some notes I can share:
- At the moment Proteus V4 is still under heavy development and is still in the “Alpha” stage of development.
- Proteus V4 is given this “Alpha” tag because it hasn’t been optimised for performance, is still under development (as pointed out before), you can only do a 4x upscale (presumably 2x is planned for the future), and some of the settings to adjust Proteus V4 aren’t doing much or aren’t working properly.
- Along with all that, Proteus V4 has a tendency to reduce the detail in videos when compared to Proteus V3.
- Also, Proteus V4 can introduce various artefacts like blotches, halos, etc
Is there anything good about Proteus V4?
Yes, however I’m not sure I can share that with you since you aren’t a beta tester. So all I will say is that Proteus V4 is the model they reference in these places:
