Digital Twins, Sharper Product Studio, and the Work You Don't See

The last few releases were big swings. Group shots. Shot Planner. Major architectural moves. This one is different. This is the release where we go back through everything we shipped, listen to what you told us, and refine the edges.

A lot of it came directly from your feedback.

Bring your own model: digital twins are here

If you have an AI model portrait you already generated and are happy with, or a real model portrait you have the rights to use, you can now bring it into Brandmachine directly. Upload the portrait, optionally include a set card, and the platform builds the model around it. If no set card is provided, we generate one for you.

This is the digital twin path. You are no longer locked into casting from scratch every time. The model you have, the look you have already invested in, the talent you have a license for: bring it in, use it across campaigns and Product Studio, and keep your visual identity consistent.

This one is bigger than it sounds. It changes who can use Brandmachine and what they can carry over from work they have already done.

Product Studio: a lot of detail work

Product Studio got a meaningful pass of refinement. The prompts had been a bit constrained. Defaults were leaning the model in directions you may not have wanted. We dug into it and rebuilt how prompts get assembled.

The honest framing: this is the kind of work a brand should not have to do themselves. To validate one of the changes (where in the prompt custom instructions sit and how strongly the model follows them), we ran a structured experiment with 23 contradictory-instruction tests. End-of-prompt instructions won 87% of the time. That is the kind of analysis no brand wants to spend time on, and it is exactly what we should be doing for you so the defaults just work.

The practical effect for you:

• Your per-perspective custom instructions now carry significantly more weight. If you wrote them and felt they were being ignored, try them again. They actually do what they say now.
• Default lighting is no longer biased to one side. The previous default pulled Gemini toward a consistent left-side lighting pattern across every image. That bias is gone. If you preferred the old look, add "studio-lit" to your custom instructions and you will get it back, with stronger adherence than before.

A new fast model for quick iteration (beta)

We added an opt-in beta path that routes specific perspectives to Nano Banana 2 instead of Gemini 3 Pro. Add [fast] to a perspective name for 2K output, or [fast4k] for 4K. It is faster and cheaper, useful when you want to iterate quickly on an idea before locking it in.

The longer goal here is pack shots and flat lays. We already added the product-only perspective flag (which optimizes the prompt and input for product-only shots), and the fast model is one more step toward making the pack shot pipeline genuinely optimal. If you shoot a lot of pack shots, try [fast] perspectives and tell us where it falls short.

Archive perspectives you no longer use

Small but useful. Perspectives can now be archived and restored. Archived ones disappear from the default list but their generated outputs are preserved. Useful for cleaning up a workspace without losing history.

The bigger picture

After a stretch of big jumps, this release is about going back and tightening what we already shipped. The prompt engineering work, the digital twin path, the fast model beta, the small organizational improvements: all of it came out of watching how you actually use the product and where the rough edges were.

Keep telling us where it still falls short. We are reading everything.
