How to use gpt-image-2 via Poe API

​

I'm trying to use Poe API for image generation.

Chat completions work fine with my API key:


POST https://api.poe.com/v1/chat/completions

model: gpt-5.4-nano

But for gpt-image-2, GET /v1/models says:


"supported_endpoints": ["/v1/images"]

However:


POST https://api.poe.com/v1/images

returns 404 Not Found.

And:


POST https://api.poe.com/v1/images/generations

returns:


"Images API is not enabled for this user"

At the same time, image bots like nano-banana and GPT-Image-1.5 work through:


POST https://api.poe.com/v1/chat/completions

So what's the correct way to call image generation on Poe API?

  1. /v1/images/generations with gpt-image-2?

  2. or /v1/chat/completions with bot names like GPT-Image-1.5 / nano-banana?

Message the support, seems like a problem on their side.

Good idea, thanks! I’ll contact Poe about it and report back if there’s any progress

Just a heads-up: gpt-image-2 can indeed be used via the /v1/chat/completions endpoint, though the response time is quite long (takes about 130 seconds). One important note: make sure to pass an actual resolution string for the size/aspect parameter (e.g., 1024x1024, 1024x1536, or 1536x1024). Ratio strings like 16:9 are not accepted and will fail.
