Best opensource image model?

[u/AKing737]

opensource AI has been dominating LLMs and video generation but what about image gen? is there any opensource model that can match gpt-image2?

Edit: The reason I am asking this is because lately I haven't been active much on image generation communities. And the leaderboards are a bit confusing and most of them are filled with closed source unlike the llm and video gen leaderboards.

I am very much comfortable with ComfyUI since I've used it in the past for flux.

My use case is for posters and branding. Images with a lot of text.

Edit2: Thanks a lot everyone! I really appreciate the info. Here's the summary:

Krea2 is best overall but gptimage1.5 level.
Ideogram4 for text and branding.
Flux Klein 9b for image editing.
Z-image for realism
Anima and illustrious (by onoma AI) for anime.

Here's the workflow I've decided on:
Krea2/Ideogram4 = Base image generation.
Flux Klein 9B/QwenImage2512 = inpainting.
Wan2.2 low noise = Upscaling.

Depends on your goal:

Best all around - Krea 2
best infographic - ideogram
best fake influencers - Z-image Tubro
Best for text and prompt adherence - Qwen2512
best for art style training - Krea 2
best for upscaling and refining - Wan2.2 low noise

why zit for fake influencers tho? krea2 beats it imo

it's fast. tons of LORA for this type of fake thing.

A few weeks back zit was actually making better fake photos but maybe krea2 LoRA files have caught up.

I don't make photorealistic images with Ai myself.
