Still seems to have problems with transparent backgrounds.

  That's expected with any image generating models because they aren't trained with an alpha channel. It's more pragmatic to pipeline the results to a background removal model. EDIT: It appears GPT-4o is different as there is a video demo dedicated to transparancy.

    There's an entire video in the post dedicated to how well it does transparency: https://openai.com/index/introducing-4o-image-generation/?video=1069289433 https://openai.com/index/introducing-4o-image-generation/?vi... I suspect we're getting a flood of comment from people who are using Dall-E.

      Huh, I missed that. I'm skeptical of the results in practice, though.

      The video was helpful. I started with the prompt "Generate a transparent image. " And that created the isolated image on a transparent background. Thank-you.

    This one however explicitly advertises good transparency support.

    There's a mod for stable diffusion webui forge/automatic1111/ComfyUI which enables this for all diffusion models (except these closed source ones).

      SD extensions like rembg are post-processing effects - with their video transparency demo I'd be curious if 4o actually did training with an alpha channel.
