About

What sd is

SD-Turbo Model Card SD-Turbo is a fast generative text-to-image model that can synthesize photorealistic images from a text prompt in a single network evaluation. We release SD-Turbo as a research artifact, and to study small, distilled text-to-image models. For increased quality and prompt understanding, we recommend SDXL-Turbo. Please note: For commercial use, please refer to https://stability.ai/license. Model Details Model Description SD-Turbo is a distilled version of Stable Diffusion 2.1, trained for real-time synthesis. SD-Turbo is based on a novel training method called Adversarial Diffusion Distillation (ADD) (see the technical report), which allows sampling large-scale foundational image diffusion models in 1 to 4 steps at high image quality. This approach uses score distillation to leverage large-scale off-the-shelf image diffusion models as a teacher signal and combines this with an adversarial loss to ensure high image fidelity even in the low-step regime of one or two sampling steps. - Developed by: Stability AI - Funded by: Stability AI - Model type: Generative text-to-image model - Finetuned from model: Stable Diffusion 2.1 Model Sources For research purposes, we recommend our generative-models Github repository (https://github.com/Stability-AI/generative-models), which implements the most popular diffusion frameworks (both training and inference). - Repository: https://github.com/Stability-AI/generative-models - Paper: https://stability.ai/research/adversarial-diffusion-distillation - Demo [for the bigger SDXL-Turbo]: http://clipdrop.co/stable-diffusion-turbo Evaluation The charts above evaluate user preference for SD-Turbo over other single- and multi-step models. SD-Turbo evaluated at a single step is preferred by human voters in terms of image quality and prompt following over LCM-Lora XL and LCM-Lora 1.5. Note: For increased quality, we recommend the bigger version SDXL-Turbo. For details on the user study, we refer to the research paper. Uses Direct Use The model is intended for both non-commercial and commercial usage. Possible research areas and tasks include - Research on generative models. - Research on real-time applications of generat

Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys sd for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (sd below is illustrative; you get the exact model name on deployment.)

$ curl -sS https://api.axforge.ai/v1/images/generations \
  -H "Authorization: Bearer $AXFORGE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"sd","prompt":"a red bicycle","size":"1024x1024"}'

Licence

Commercial licence needed

The weights are open but its licence needs a commercial agreement for business use. AxForge can arrange that licence and host the model for you — you pay AxForge, we settle with the model’s maker. Ask us for a quote. Read the licence ↗
