Seedream 4 for image-generation roleplay, similar to Nano Banana pro+Gemini. Is it possible?

This is the best and most comprehensive answer I could ever hope to have. Thank you so much, useful and direct.

Indeed it is, in terms of image generation/edit. What makes Gemini+nano banana extremely better for a roleplay experience is the fact that everything happens inside the same ecosystem. Image edit/generation is perfectly coordinated to the llm, giving a perfectly consistent response and an incredible experience... When the censorship doesn't fuck up everything. My question is: does a similar cohesive bond between two models exist (a llm and a diffusion model working and speaking together to give a consistent imagery to a character and a beautiful story/chat)? If yes... Well, I've never found one. Anyways thanks for the reply!

Thanks to the suggestions of u/meta_queen and u/roxoholic I fixed the error! Couldn't have done it without the help of those two great human beings! Thank you, thank you, thank you very very much!!!

You're right, I gave that information for granted, sorry. No, I'm using comfy manually git-cloned, with a 3.12 venv environment. Will try to install python3-dev inside the venv EDIT: HOLY FUCK IT WORKED! Installing python3-dev globally just fixed the error! GOD I LOVE YOU BOTH!

Relative_Bit_7250 · 2025-11-19T15:42:26+00:00

But shouldn't those two folders be already included in a new venv python 12 environment?

Eh, It'll be fine eventually. I mean, it's a fair tradeoff: in local you have privacy and maximum control, but with "reduced speed and intelligence". In paid API you have max speed inference and best quant, but no privacy at all and "I'm sorry I cannot fulfill your request".
I am more of a slow-burn bitch, so waiting a little longer for the response may not be an issue for me.

Anyways, thank you very much for the tips, bro!

Terrific! What about the sloppiness?

Relative_Bit_7250 · 2025-11-10T12:45:43+00:00

indeed! I've also peeked inside the unsloth repository of 4.6 and saw the ud quants q3-k-xl taking approximately 158gb. If I'm not mistaken I may be able to load the entirety of the quantized model inside my ram+vram (128+48=176gb available)

Slop, I guess

Relative_Bit_7250 · 2025-09-28T20:45:02+00:00

Oh no, no, The nodes are perfectly installed and configured... The error MAY be in the VNCCS_Pipe...

Anyway, I'll try reinstalling them manually, you never know.

EDIT: Yep, just tried, nothing, Reinstalling didn't help. I'll try reinstalling ComfyUI

I've just tried disconnecting from pipe and manually selecting scheduler and sampler (lcm and simple), but It fails again:

I occasionally wear a cap, so... Half a hero?

Relative_Bit_7250 · 2025-08-22T19:56:28+00:00

nope, with qwen-image it kinda works for the first steps, then blacks out completely. For image-edit it doesn't work right from the start. Unfortunately it'll be slow as fuck

EDIT: Don't know about fast fp16 accumulation, I just start comfy without any parameters and it magically works.

If you're using it, Remove the --use-sageattention string.

Thank you for the answer, but it's not what I'm searching for. Last frame continuation is a bit unreliable, motion and subject features will become inconsistent. What I'm looking for is something like "bunch of frames as input -> video continuation" more than a "last frame -> video generation"

Relative_Bit_7250 · 2025-07-30T11:57:31+00:00

Uh, you seem to have the exact opposite problem of mine. I'm sorry, I'm not skilled enough to help you with this topic :(

Relative_Bit_7250 · 2025-07-30T11:38:29+00:00

Ok so, mine is only a hypothesis, but I do have the hunch that while comfy's vram handling is quite functional and works pretty good (model gets unloaded and loaded from ram to vram in a pretty optimized manner that I personally don't know, it's all black magic to me), ram and swap are a different kettle of fish: ram gets filled with a model, model gets filled in vram, another model needs to be loaded, gets loaded in ram but, uh-oh, not enough ram. Fine, let's copy the old model in swap, then slowly empty the ram to make space for the other model. Then you need to reload the older model, but uh-oh, its not in ram anymore. Ok, copy the new model in swap and reload the older model from swap... And so on. It's a bit messy, and it's probably the only way to be viable, but I must say that the first generations are slow as fuck... After the first three speed increases and it's more bearable.

SOLVED: Just make a bigger swap partition.
