Removing getimg's internal model is a mistake. We dont' mind about losing Stable Diffusion (and understand that people may be mislead into creating crappy results with no understanding that these models are outdated).
Essential Photorealistic V2 is something which made your service unique.
Every other hosted platform like yours have a proprietary model, and the model you created was the best. It was something you could find only on your platform.
Of course other models today are considered crop top at the moment, but they give zero contribution into making your service unique. Nano Banana? Sure. But that's Google's model, its not getimg's model, you can find Nano Banana running through API within any other service, you can use it on Gemini for cheaper, and its exactly the same Nano Banana you are hosting. Same goes with other models like Grok or GPT.
By removing Getimg's Essential you are not only removing something that people use "this % of the time" so you think its not worth the cost anymore. You are losing in terms of what makes your service unique, and what could make your service something different then an equivalent that could be replaced with any other service.
I would glady play 5x or 10x the cost per image to keep using Essential V2 to put it more on par with Flux and other similar models you are hosting. Think about it.
