What Control Light is for
Control Light starts from a still you upload, then edits it from your prompt. A typical run takes about 10 seconds at Credits. Use it when you already have a frame and need a new version, not a picture from scratch.
Control Light is cheap enough that a generation usually fits the free Knowlify plan's credits. A typical run is about 10 seconds.

Frequently asked questions
How do I run Control Light?
Run Control Light on Knowlify at /generate/control-light. Write the prompt on this page and it opens in the studio, where Control Light generates a still image. The same studio also turns documents into full narrated videos.
Where can I use Control Light online?
On Knowlify (knowlify.com/generate/control-light). You do not need a separate playground. Control Light runs in the studio next to document-to-video.
Can I make a longer video with Control Light?
Control Light itself produces a still image. On Knowlify you can take that output, or skip it and upload a document, and generate a full narrated video with a script you can edit.
What do I need to run Control Light?
A prompt and a source still. Control Light will not invent the starting frame for you on this mode.
How long does Control Light take?
Plan on about 10 seconds for a typical run, then whatever queue time the studio has. Video models sit at the high end of that range.
What does ControlLight cost?
Knowlify charges this as credits, at the compute cost.
What is ControlLight best for?
ControlLight is a LoRA fine-tune of FLUX.2 [klein] 9B that enhances low-light images while preserving scene structure and fine details, with a single alpha parameter that gives continuous control over enhancement strength from subtle to full brightening. It edits an image you upload.
Do I need an account to use ControlLight?
Yes, a free account. The prompt you write here is waiting for you when ControlLight opens in the studio.
