Key Takeaways
- Stable Diffusion 3 Medium is Stability AI's most advanced text-to-image open model yet.
- The small size of this model makes it perfect for running on consumer PCs and laptops as well as enterprise-tier GPUs. It is suitably sized to become the next standard in text-to-image models.
- The weights are now available under an open Community License. For large-scale commercial use, please contact us for licensing details.
- To try Stable Diffusion 3 models, try using the API on the Stability Platform, sign up for a free three-day trial on Stable Assistant, and try Stable Artisan via Discord.
We are excited to announce the launch of Stable Diffusion 3 Medium, the latest and most advanced text-to-image AI model in our Stable Diffusion 3 series. Released today, Stable Diffusion 3 Medium represents a major milestone in the evolution of generative AI, continuing our commitment to democratising this powerful technology.
What Makes SD3 Medium Stand Out?
SD3 Medium is a 2 billion parameter SD3 model that offers some notable features:
- Overall Quality and Photorealism: Delivers images with exceptional detail, color, and lighting, enabling photorealistic outputs as well as high-quality outputs in flexible styles. Success in addressing common pitfalls of other models, such as realism in hands and faces, is achieved through innovations such as the 16-channel VAE.
- Prompt Understanding: Comprehends long and complex prompts involving spatial reasoning, compositional elements, actions, and styles. By utilizing all three text encoders or a combination, users can trade off performance for efficiency.
- Typography: Achieves unprecedented text quality with fewer errors in spelling, kerning, letter forming, and spacing by leveraging our Diffusion Transformer architecture.
- Resource-efficient: Ideal for running on standard consumer GPUs without performance degradation, thanks to its low VRAM footprint.
- Fine-Tuning: Capable of absorbing nuanced details from small datasets, making it perfect for customisation.
