Promethean AI

- Layers onto an existing pipeline instead of demanding migration
- Retrieval of owned work sidesteps the provenance questions generation raises
- The artist-first position is backed by a costly and checkable action
- The tenfold and hundredfold claims carry no source
- Only Unreal is a primary integration; other editors carry version caveats
- Deployment realistically needs a technical artist
