SDXL 0.9 release for research, public 1.0 mid-July

I hope the open release next month will finally be a nice upgrade from SD1.5 and will be a good starting point for lots of new models.

I feel like I've been waiting for the release for ages. I'm really excited to see how popular this model will be for checkpoints.

Looking forward to the performance improvements.

What’s under the hood?

The key driver of this advancement in composition for SDXL 0.9 is its significant increase in parameter count (the sum of all the weights and biases in the neural network that the model is trained on) over the beta version.

SDXL 0.9 has one of the largest parameter counts of any open source image model, boasting a 3.5B parameter base model and a 6.6B parameter model ensemble pipeline (the final output is created by running on two models and aggregating the results). The second stage model of the pipeline is used to add finer details to the generated output of the first stage.

Availability

SDXL 0.9 is now available on the Clipdrop by Stability AI platform. Stability AI API and DreamStudio customers will be able to access the model this Monday, 26th June as well as other leading image generating tools like NightCafe.

SDXL 0.9 will be provided for research purposes only during a limited period to collect feedback and fully refine the model before its general open release. The code to run it will be publicly available on Github.
