Stability AI API Change #69

Closed Rocky56gh9 closed 1 month ago

Rocky56gh9 commented 1 month ago

The Stability AI API path has changed as of 10/11/24. The prior URL is no longer supported. I tried manually changing in all places that I found it to the new URL but there seems to be fundamental differences in how it works, so I'm not sure how to re-engineer independently. I am unable to get DALL-E to generate with an API key. In all cases, I'm just getting the test image now.

TLDR update stable_host = "https://api.stability.ai/v1/generation/stable-diffusion-v1-6/text-to-image" in .config and it should work again.

The API path or how it functions does not appear to have changed but the model that was in the path has been deactivated. We should start using stable-diffusion-v1-6 instead. I have updated this and tested as working. From https://platform.stability.ai/docs/api-reference#tag/SDXL-1.0-and-SD1.6/operation/textToImage: SD1.6 is a flexible-resolution base model allowing you to generate non-standard aspect ratios. The model is optimized for a resolution of 512 x 512 pixels

If you try to use one of the larger/XL models it won't work as the image size is too big for our resize operations. The smaller models work better as e-paper displays tend to be smaller than the 1024*1024 that XL models like, so IMO refactoring the stable diffusion code to allow for XL models wouldn't be a priority (saying that, happy for someone to merge to implement if they like, it shouldn't be too hard).

As for dalle, I am not sure, can you please provide logs and your config? I have confirmed dalle is still working on my implementation.

Please let me know if the above works.

Thank you! The "stable_host" change works.

Re: Dall-E, the logs consistently show it just stopping at "Getting Image." It never progresses beyond that. I'm not too concerned as I prefer the Stability.AI output anyway, so I'm happy with that working again.

Will need to keep an eye on that dalle issue, it looks like possible something to do with string parsing. I'll close this issue off for now.
