Any workflows for an ai consistent character generation?

To maintain 90% similar identity across different poses has been my primary focus for a few weeks, and it is clear the industry has moved past basic prompting. So, I have been testing how different models handle identity embed dings, also finding that reference-based generation is now reliable enough for rapid prototyping. Been testing out mostly SD but also Flux and Seedream through separate tools, Comfy, and all in one like writingmate. That is also to quickly cycle through 200+ models to see which ones hold a face structure best when changing artistic styles.
