AI Image Generation Model Comparison: Text to Image Generation (T2I)

What is AI image generation?

AI image generation refers to the process by which a machine-learning model creates an image (or images) based on input data such as a text prompt, a sketch, or some image seed. The model has been trained on large datasets of images (often paired with captions) and learns to synthesise new visual outputs that correspond to the guidance given. In short: you describe something in words or provide a visual cue, and the model produces a new image that matches the description.

In many cases, this process is made available via text to image APIs — services that allow developers or creators to call a REST endpoint or SDK, supply a prompt (for example: “a futuristic cityscape at sunset”), and receive generated images back. These text to image APIs abstract away the complex model-hosting and inference infrastructure and let you integrate image generation into apps, workflows or creative tools. Platforms such as Pixazo provide APIs with a wide model catalogue.

Because of the speed, scalability and creative possibilities they enable, AI image generator tools are increasingly used in advertising, concept art, social media content, prototyping, and more. Compared to traditional manual design workflows, they can cut cost and time, allow rapid iteration, and unlock styles or visuals that might otherwise be difficult to produce.

Why AI Image Generation Matters?

AI image generation enables users to create high-quality images from simple text prompts, drastically reducing the time and cost of traditional image creation. Here’s why this technology is crucial:

• Efficiency: Generate images quickly without the need for expensive equipment or lengthy production processes.
• Innovation: Unlock creative potential and explore visual styles that were once unimaginable.
• Customization: Fine-tune outputs to match your artistic vision or brand identity.
• Scalability: Produce multiple variations for A/B testing or personalized campaigns.
• Accessibility: Empower individual creators and small teams with tools that were once only available to large studios.

Why Does Choosing the Right Model Matter?

Not all AI image generation models are the same. They differ in criteria such as photorealism vs stylisation, prompt adherence (how well the generated image reflects the text input), text rendering (if the image includes readable text), vibration/creativity vs fidelity, speed of generation, licensing (open source vs closed), and how well they handle edge cases. For example, some models excel at producing realistic photography-style images, others lean toward artistic/illustrative styles, while still others prioritise very fast inference for interactive apps. The wrong choice might result in visuals that look off, or poor performance in your workflow.

By understanding the comparative strengths and limitations of leading models, you can select the right one for your project (e.g., for marketing, branding, rapid prototyping, concept art, or production-grade visuals). That’s why the comparison below is structured around each model’s overview, use case, pros and cons.

With these advantages, choosing the right AI image generation model is key to staying competitive and innovative.
