Stable Diffusion: Generative AI On Your Desktop Through Delphi

Welcome, art enthusiasts, developers, and innovators! Generative AI is turning into a powerful force in the software development and content creation spaces. In this article we will explore the Stable Diffusion Desktop client – a desktop UI designed to give you access to a whole host of Stable Diffusion models for image generation without having to have a GPU on your Windows, macOS, or Linux machine. Additionally,  it provides access to upscaling models to supersize the images you create.

What is Generative AI?

Generative AI refers to a subset of artificial intelligence models that can produce new, previously unseen content by learning from a set of data. Rather than just making decisions based on existing information, generative models can create data that mirrors, in structure and style, the original dataset. These models are often used in tasks such as generating images, music, text, or even video based on patterns they’ve identified during their training phase.

The underlying principle for most generative models is the idea of understanding and capturing the distribution of the input data. Techniques like Generative Adversarial Networks (GANs) and Variational Autoencoders (VAEs) are popular methodologies in this domain. With the rise of deep learning, generative AI has seen significant advancements, leading to innovations like realistic image generation, content creation, and even aiding drug discovery.

What is Stable Diffusion?

Stable Diffusion, introduced in 2022, is a generative AI text-to-image deep learning model based on diffusion techniques. The model primarily translates text descriptions into detailed images. The model’s architecture is publicly available, making it distinct from other cloud-only models like DALL-E and Midjourney. A whole host of community trained models have sprung up around Stable Diffusion enhancing it and the images it can create.

This deep generative neural network uses a latent diffusion model, with its underlying technology involving the iterative denoising of noise, guided by a text encoder, to produce the desired image. A notable characteristic of Stable Diffusion is its ability to run on consumer GPUs, unlike other heavyweight models. There have been a number of releases of Stable Diffusion which have increased the training image size from 512×512 (Stable Diffusion 1.5) to 1024×1024 (SDXL).

What Models Can You Access with the Stable Diffusion Desktop Client?

Users are provided with a wide palette of Stable Diffusion models, such as:

  • Stable Diffusion 1.5
  • SDXL
  • DreamShaper
  • Realistic Vision v5.1
  • PortraitPlus
  • OpenJourney
  • Stable Diffusion 2.1
  • Edge of Realism … and many more.

Need Upscaling Abilities? What Does the Client Offer?

The client isn’t just about creating – it’s also about enhancing. Offering tools integrated with:

  • Codeformer (facefix)
  • Real-ESRGAN (facefix)
  • Swin2SR
  • GFPGAN (facefix)
  • Swinir
  • Rundalle-sr
  • Esrgan … and others.

How is Cross-Platform Compatibility Achieved?

Cross-platform compatibility is a design approach that allows software applications to function on multiple operating systems or environments with minimal modifications. Embarcadero’s Delphi, paired with the FireMonkey framework, is a prime example of this. At its core, Delphi is a versatile programming language, and FireMonkey (often abbreviated as FMX) is a cross-platform GUI toolkit designed for this very purpose. Together, they provide a robust foundation for developing applications that can effortlessly span multiple platforms.

The Stable Diffusion Desktop client, built upon this combination, has been primarily optimized for Windows. However, its inherent design allows for easy adaptability across a variety of platforms, including macOS and Linux. Moreover, with some tweaks, it can even be ported to mobile ecosystems like Android and iOS. This broad-spectrum compatibility is achieved through an abstraction layer provided by the FireMonkey framework, which translates general code into platform-specific executions. Thus, developers can write their code once and deploy it across multiple platforms, saving both time and resources.

How Does It Benefit Delphi Developers?

Delphi, as a development platform, has been serving developers for decades, offering tools that streamline coding processes. With the evolution of the FireMonkey (FMX) framework, Delphi has taken a leap forward in terms of user interface development. For seasoned Delphi developers, the direct ability to copy an FMX TImage from the client into the Delphi Integrated Development Environment (IDE) offers a range of benefits:

  • Efficiency: By allowing direct transfers, developers can sidestep the often cumbersome process of manually exporting, saving, and importing images. This not only cuts down the number of steps involved but also reduces the chances of errors.
  • Unified Workflow: Having the capability to seamlessly move components between the client and the Delphi IDE ensures a more cohesive and unified development process. This continuity helps in maintaining consistency and standards across the project.
  • Rapid Prototyping: For developers who are in the process of designing or tweaking the user interface, this feature facilitates rapid prototyping. Changes can be visualized and tested quickly, speeding up the iterative design process.
  • Time Savings: As with any streamlined process, the most tangible benefit is time. What might have taken minutes in a traditional workflow can now be accomplished in seconds, freeing up developers to focus on more complex tasks.

In essence, this integration between the client and the Delphi IDE represents a significant quality of life improvement for developers, simplifying and enhancing their everyday tasks.

What Makes it More Than Just Another Desktop Client?

It has an integration with Replicate.com via REST to not only facilitates direct interfacing with online resources but also allows for a richer user experience due to the expanded functionality. By connecting with external platforms, users can access a plethora of tools and features without having access to the necessary GPU on the client. Additionally, it utilizes Skia4Delphi, an embedded component of the client, offers users a significant advantage when it comes to rendering. Recognized for its high-speed performance, Skia4Delphi ensures that images are displayed quickly.

Beyond these features, the client’s open-source nature elevates its stature. It ensures transparency, fosters community contributions, allows for unparalleled customizability, and reduces cost barriers. You can adapt the client or code for use within your own projects.

Ready to get started with Stable Diffusion?

In an era where AI and creativity often intersect, the Stable Diffusion Desktop Client stands as a tool showing what’s possible for incorporating Stable Diffusion into your own projects. Whether you’re a developer looking for the next big tool to integrate into your workflow or an artist eager to explore new horizons, this open source project can get you started with generative AI.

As they say, seeing is believing. Dive into the world of Stable Diffusion and unleash your creative prowess!
