What is Stable Diffusion v3.0?
Stable Diffusion v3.0 is Stability AI's powerful text-to-image model line in the Stable Diffusion family, featuring superior quality and market-leading prompt adherence. The models use a Multimodal Diffusion Transformer (MMDiT) architecture with separate weights for image and language representations, improving text understanding and spelling capabilities compared to previous versions. They generate high-resolution images at 1 megapixel with diverse artistic styles including 3D, photography, painting, and line art.
The Stable Diffusion v3.0 generation includes several variants: a Large-scale model (8.1 billion parameters) for professional use cases, a distilled Turbo version generating images in just 4 steps, and a Medium model (2.5 billion parameters) designed to run on consumer hardware with only 9.9 GB VRAM requirements. The family excels in prompt adherence, versatile style generation, diverse outputs representing people worldwide, and customizability for fine-tuning.
Stable Diffusion v3.0 models are for researchers, developers, hobbyists, startups, and enterprises needing professional-grade image generation. Users can access them through a self-hosted license (download from Hugging Face), the Stability AI API, cloud partners like Amazon Bedrock, or web-based applications like Stable Assistant. The models support image editing services including erase object, inpaint, outpaint, remove background, upscale, and control tools for sketch structure and style transformation.
Stable Diffusion v3.0 pricing
Pricing model: Freemium
Stable Diffusion 3.5 is free under the Stability AI Community License for non-commercial use and commercial use for organizations with less than $1M annual revenue. The Community License includes Stable Diffusion 3.5 Suite, SDXL Turbo, Stable Audio 3.0, and Stable Fast 3D. Organizations with annual revenue exceeding $1M must contact Stability AI for a paid Enterprise License which includes commercial use and implementation support, with available upgrades for custom model training and consulting services at custom pricing. API access through Stability AI Developer Platform and cloud partners like Amazon Bedrock, Replicate, Fireworks AI, DeepInfra, and ComfyUI may have separate usage fees.

Frequently asked questions about Stable Diffusion v3.0
Is Stable Diffusion 3.5 free to use?
Yes, Stable Diffusion 3.5 is free for everyone unless you're using it for commercial purposes and your organization generates over $1M in annual revenue. The Stability AI Community License allows research, non-commercial, and commercial use for individuals or organizations generating under $1M annually regardless of revenue source.
What are the differences between Stable Diffusion 3.5 Large, Turbo, and Medium?
Stable Diffusion 3.5 Large has 8.1 billion parameters and is the most powerful for professional use at 1 megapixel resolution. Large Turbo is a distilled version generating high-quality images in just 4 steps, considerably faster than Large. Medium has 2.5 billion parameters, designed to run on consumer hardware with 9.9 GB VRAM, balancing quality and customization for 0.25 to 2 megapixel resolution.
Can I use Stable Diffusion 3.5 for commercial purposes?
Yes, commercial use is free for businesses with less than $1M annual revenue under the Community License. For organizations making over $1M annually, you must contact Stability AI to purchase an Enterprise License for commercial use rights.
Do I own the images I generate with Stable Diffusion 3.5?
Yes, you own the outputs generated from Stable Diffusion 3.5 or its derivative works like fine-tunes. You can use those outputs at your discretion as long as you comply with applicable law and Stability AI's Acceptable Use Policy.
How do I download and self-host Stable Diffusion 3.5?
You can download all Stable Diffusion 3.5 models from Hugging Face and get the inference code on GitHub. The models are available under the permissive Stability AI Community License for self-hosting on your own infrastructure.
What hardware do I need to run Stable Diffusion 3.5 Medium?
Stable Diffusion 3.5 Medium requires only 9.9 GB of VRAM excluding text encoders to unlock full performance, making it highly accessible and compatible with most consumer GPUs. NVIDIA chips are recommended.
Can I fine-tune Stable Diffusion 3.5 for my specific needs?
Yes, the models are highly customizable and designed to be easily fine-tuned for specific creative needs. Query-Key Normalization was integrated into transformer blocks to stabilize training and simplify further fine-tuning and development. You can build LoRAs, hypernetworks, and fine-tunes based on the model.
What image editing tools are available with Stable Diffusion 3.5?
Stability AI offers 13 specialized image editing tools including Edit (erase object, inpaint, outpaint, remove background, search and recolor, search and replace, replace background and relight), Upscale (creative, conservative, fast), and Control (sketch, structure, style) for transforming variations of images or sketches.
Where can I access Stable Diffusion 3.5 besides self-hosting?
You can access Stable Diffusion 3.5 through the Stability AI API, Replicate, Fireworks AI, DeepInfra, ComfyUI, cloud partners like Amazon Bedrock, or web-based applications including Stable Assistant which provides access to all models and editing tools.
What is the Stability AI Community License?
The Community License is a permissive license allowing research, non-commercial, and commercial use for individuals or organizations generating under $1M annual revenue regardless of revenue source. It includes ownership of outputs, allows distribution and monetization of work across the entire pipeline including fine-tuning, LoRA, optimizations, applications, and artwork. The license is revocable if terms are violated.
