More premium image models (Z-Image Turbo, Flux.2, etc.)

Current premium models are amazing, but super expensive. A single generation with Seedream 4.5 costs 12 cents, and doing multiple takes leads to ~50 cents per single image. Completely free models, by comparison, are too low-quality. An intermediate between these two is needed.

I would like to request more models to be added because of this. Z-Image Turbo is a very good model in my experience - better than Qwen-Image while weighing only 6 billion parameters. It can either be a free model or extremely cheap (1 credit per generation or less).
Flux.2 Pro is also amazing in quality - comparable to SeeDream 4.5 / Nano Banana, and locally hosted so it can be cheap.

From what I understand, adding these models will not take a lot of work - so I would like to please request the devs to add them. 🙏
