what is stable diffusion 3(SD3)?

Stable Diffusion 3 (SD3) is the latest image generation model developed by Stability AI.

Is Stable Diffusion 3 available now?

Stable Diffusion 3 and Stable Diffusion 3 Turbo are now available on the Stability AI Developer Platform API. We have partnered with Fireworks AI, the fastest and most reliable API platform in the market, to deliver Stable Diffusion 3 and Stable Diffusion 3 Turbo.

Will Stable Diffusion 3 be free?

the specific terms of use, including whether there will be a completely free tier or any potential costs associated with using SD3, can vary and are determined by Stability AI's policies and the licensing of the technology.

How big is Stable Diffusion 3?

Stable Diffusion 3 is not one model, but a whole family of models, with sizes ranging from 800 million parameters to 8 billion parameters.

Is Stable Diffusion 1 or 2 better?

While it is difficult to come up with an objective measure for how well these models generate text, it could be argued that the average person would consider Stable Diffusion 2 to be slightly better.

What are the new features of Stable Diffusion 3?

Stable Diffusion 3, or SD 3, is the latest image generation model from Stability AI. They highlight improvements like better photo-realistic image generation, adherence to strong prompts, and multimodal input. SD 3 constitutes a suite of models of small sizes, from 800 million parameters to 8 billion parameters.

key points and highlights about SD3?

Variable Model Sizes

The SD3 series offers models with varying parameter counts, ranging from 8 million to 8 billion, designed to run smoothly on a variety of portable devices and significantly reduce the deployment difficulty of large AI models.

Enhanced Image Generation Quality

Compared to the previous SDXL version, SD3 has made significant improvements in image generation quality, including clarity, detail richness, and optimized handling of multi-subject prompts.

Improved Text Generation Model

SD3 has also enhanced its text generation capabilities, accurately simulating and reproducing various fonts and writing styles, which is crucial for image creation requiring high-quality textual elements.

Open-Source Commitment

Emad Mostaque, CEO of Stability AI, has indicated that the company plans to open-source the SD3 model to embody the true spirit of the internet.

Technical Architecture

SD3 employs a Diffusion Transformer (DiT) architecture, similar to Sora's technology, which improves the model's efficiency and the quality of the generated images.

Safety Measures

The Stability AI team is implementing a series of safety measures to prevent potential malicious use of the technology.

Effect Comparison

Compared to other models like DALL·E 3, SD3 has significant improvements in resolution, color saturation, composition, and texture, resulting in more realistic and detailed images.

Multimodal Input

SD3 leverages improvements in transformers to accept multimodal inputs, allowing for further expansion.

Model Scales

SD3 provides models of different scales, with parameter counts ranging from 800M to 8B, enabling it to run on various devices, including portable ones, and lowering the barrier to entry for using large AI models.

API Availabilitys

Stability AI announced that Stable Diffusion 3 and its faster version, Turbo, are now available to developers via API.

Research Paper

A research paper on the new Multimodal Diffusion Transformer (MMDiT) architecture and Rectified Flow formulation that powers SD3 has been released.

Developer Preview

SD3 was released in preview to a small number of developers in February, with Stability AI stating that SD3 "equals or outperforms" other image generation models.

Image and Video Generation

There is a belief that with more GPU resources, Stability AI might train stable videos based on SD3 to reach the level of Sora.

3D Generation

Emad Mostaque has also showcased 3D works generated by SD3.
