FLUX

FLUX was a dependable image model inside our 2025 internal tools and its Kontext Pro edit model kept a face recognizable across chained edits, but it has not come up on the show since August 2025.

Our verdict on FLUX

We used FLUX as one of several image models inside our own tools in 2025, mostly for variety and for edits that keep a person recognizable. Its FLUX.1 Kontext Pro edit model handled chained photo edits well enough to demo live, though not every edit landed. It has not come up on the show since August 2025, so treat this as an early take.

What we built with FLUX

  • Ryz Labs Video Studio (June 2025): Flux Pro sits on the image page next to MiniMax Image 01. In Episode 1 (at 17:09) Jordan generated a golden retriever skateboarding through Venice. Image generation was much faster than video, and there were still some bugs.
  • Ryz Labs Autoblogger (July 2025): text comes from ChatGPT and Claude, images from OpenAI's models and FLUX. Jordan added FLUX so the posts would not all have the same look. The tool has published about 150 posts per brand.
  • AI image editing chatbot (August 2025): built in a day. You upload a photo, describe an edit, and each result becomes the starting image for the next edit. Jordan ran it on FLUX.1 Kontext Pro.

In Episode 9 (at 17:43), Jordan also ran one prompt through four image models at once in our in-house generator: Ideogram, a Google model, FLUX and a ByteDance model. He didn't spend long on the comparison.

How we use FLUX

  1. Call it through an API, inside your own tool. Every FLUX use on the show was inside an app we built, not a standalone product.
  2. Add it through Replicate. Jordan's method for the video studio: copy the sample API call and JSON schema from Replicate's model page and ask the Replit agent to add the model (Episode 1, around 24:04).
  3. Enhance the prompt first. The studio's "enhance with AI" button rewrites the prompt before it goes to Flux Pro; Jordan's view is that prompt quality strongly affects output.
  4. Mix models for variety. In the Autoblogger, FLUX runs alongside other image models so a site full of posts does not look generated by one model.
  5. Chain edits from the last result. For editing, feed each output back in as the new root image: hat, then shirt, then accents, then a cartoon style.
  6. Keep the chain short. Jordan expected some quality loss over many edits, because each result is an image of an image of an image.
So if I ask something like, you know, put a cowboy hat on Sam, I get a cowboy hat on Sam, but I still get Sam.

Where FLUX falls short

  • Harder edits. In Episode 10 (at 06:49) Sam asked for Jordan holding a green-glass beer bottle, as a product-placement test. The drinking shot did not fully work, and Sam called that part of the demo a bit of a flop.
  • Still looks AI. Sam liked how the hat's shadow fell across Jordan's shoulder, but said the image still looked a little AI generated.
  • Misuse risk. Jordan flagged that the same edits could put a beer in the hand of someone who doesn't drink, and that the real-or-fake question will get harder.
  • Thin evidence. We never ran FLUX head to head in a structured test, and we did not discuss its pricing.
Now, you have to understand these are this is like an image of an image of an image. So, you know, it continues to make changes, and we'll probably see, like, some kind of continuity degradation over time.

FLUX compared

We have no head-to-head page for FLUX. The closest comparison on the show came in the same Episode 10, when Sam asked why Nano Banana, launched the day before, had so much hype. Jordan's answer was continuity and merging images. For how Nano Banana stacks up against other image tools, see ChatGPT vs Nano Banana.

Episodes featuring FLUX

  • Episode 1: Flux Pro on the Ryz Labs Video Studio image page.
  • Episode 2: FLUX added to the Autoblogger for image variety.
  • Episode 9: one prompt across four image models.
  • Episode 10: the chained-edit chatbot on FLUX.1 Kontext Pro.

FAQ

How do you use FLUX?

We called it through APIs inside our own apps rather than a standalone app. Jordan added Flux Pro to the Ryz Labs Video Studio via Replicate and wired FLUX into the Autoblogger so blog images vary in style.

Can FLUX Kontext Pro keep the same face across edits?

In our demo, mostly yes. FLUX.1 Kontext Pro kept Jordan recognizable through a hat, a ranch background, a western shirt and a cartoon style, with natural-looking lighting, but a product-placement edit with a beer did not fully work.

Is FLUX good for blog images?

We used it for variety. Jordan integrated it into the Autoblogger alongside OpenAI's image models so that not all the images look the same in the same style.

Do you still use FLUX?

We have not discussed it on the show since August 2025. The image editing demo it powered aired the day after Nano Banana launched, and the conversation moved to Nano Banana after that.
