I've done some preliminary testing with Z-Image Turbo in the past week.

Thoughts

- It's fast (~3 seconds on my RTX 4090)

- Surprisingly capable of maintaining image integrity even at high resolutions (1536x1024, sometimes 2048x2048)

- The adherence is impressive for a 6B parameter model

Some tests (2 / 4 passed):

Personally I find it works better as a refiner model downstream of Qwen-Image 20b which has significantly better prompt understanding but has an unnatural "smoothness" to its generated images.

On fal, it takes less than a second many times.

Couple that with the LoRA, in about 3 seconds you can generate completely personalized images.

The speed alone is a big factor but if you put the model side by side with seedream and nanobanana and other models it's definitely in the top 5 and that's killer combo imho.

I don't know anything about paying for these services, and as a beginner, I worry about running up a huge bill. Do they let you set a limit on how much you pay? I see their pricing examples, but I've never tried one of these.

It works with prepaid credits, so there should be no risk. Minimum credit amount is $10, though.

This. You can also run most (if not all) of the models that Fal.ai directly from the playground tab including Z-Image Turbo.

For images I like them: https://runware.ai/ super cheap and super fast, they also support Loras and you can upload your own models.

And you work with credits

Why the down vote? Are they scam?
