5A pipeline on current models
Release notes such as “Gen-3 Alpha” matter once a pipeline runs the models; SceneMixer's guides describe how it does:
When you edit a sheet (change the hair, swap the coat, add a scar) or generate a state (the drawn blade, the burnt room), the model starts from the existing image and reads your text as what to change.
SceneMixer, Editing a Sheet or Making a State: Write the Change, Not the Whole Picture (read 2026-10-13)
Paste a scene or a short script and SceneMixer gives you a storyboard — numbered shots with framing and seconds — and then a moving version of each segment, which you can join into a rough cut of the scene.
