5 Best Image Generation Models and How Pippit Outperforms the Rest

Top 5 image generation models in 2025

Image generation models are shaping design, marketing, and content creation by producing lifelike images that once needed hours of manual work. Below, we'll review the top 5 ones:

GPT-4o

GPT-4o is OpenAI's multimodal model that handles text, image, and audio inputs and outputs. It replaces the need for separate tools like DALL·E since image generation is built into the same model. However, it is slower in producing images compared to diffusion-based image models, because it uses an autoregressive generation process. Despite that, its tight integration in modalities gives it unique advantages in precision, context, and editing.

Features

• Prompt adherence & text rendering: GPT-4o is quite good at following detailed image prompts accurately, including rendering legible text within images (e.g., signs, labels, equations).
• Image editing & iterative refinement: You can upload an image or ask for revisions, and GPT-4o will respect prior context and modify just the requested parts.
• Multimodal context & integration: GPT-4o can create images based on what's written or said in the conversation and can also use uploaded images as a reference for styles or designs.
• Built-in safety & metadata: The image generation in GPT-4o uses the same safety and moderation rules as its other outputs. Also, generated images have C2PA metadata in them to show that they were made by AI.

Google's Nano Banana

Google's Nano Banana is the image generation and editing model integrated into the Gemini app. It's designed for tasks like style transfer, object removal, and region-specific edits while preserving fine details. You just upload a photo and describe the changes you want using simple prompts or back-and-forth chats. Google presents Nano Banana as a fun and useful tool for everyday people because it lets them make changes and edits in the same workflow.

Features

• Style and outfit changes: Nano Banana can alter clothing color, material, or entire styles by following text instructions. For example, it can turn a simple dress into one made of tennis balls or swap short sleeves for long ones while preserving the original drape and lighting intact.
• Region-aware object removal: This text to image generation model supports erasing people or objects from an image while filling in the missing space naturally. It realistically fills in the missing background, like keeping reflections or extending brick wall lines.
• Background adjustments: It can blur or change backgrounds to create effects similar to pro-level photos. You might choose a soft blur for a portrait or go for bold changes that highlight the subject.
• Style transfer between images: Another strong point is the ability to mix styles in different elements. For instance, you can apply the color scheme of one object to another or give a pet the artistic style of a painting.

Adobe Firefly

Adobe Firefly is Adobe's generative AI model suite for image, vector, and video creation. It's built to integrate tightly with Adobe's creative tools like Photoshop, Illustrator, and Express to give its users smoother workflows. Its core promise is "commercially safe" content, since the models are trained only on licensed or public domain assets.

Features

• Generative fill in Photoshop: This feature lets you highlight part of an image and replace it with something new using a text prompt. The AI reads the scene around the selected area and makes sure the replacement blends naturally.
• Text-to-image generation: Firefly image generation AI model can create images from written prompts. Each description gives you four different variations to choose from, so you can pick the one that fits best. You can specify styles, lighting, and other attributes to tailor the generated image to their needs.
• Image-to-image: You can upload existing images and change their styles, colors, or add new elements.
• Integration with Adobe apps: Firefly is deeply integrated into Adobe's Creative Cloud applications, which include Photoshop, Illustrator, and Premiere Pro. This integration lets you generate and edit content within the same environment you are accustomed to.

ByteDance's SeeDream 4.0

ByteDance's Seedream 4.0 is an AI model for high-quality image generation and editing. It combines text-to-image creation, reference-based edits, and batch processing in one system. The model supports rapid inference times of 1.8 seconds for generating 2K images.

Features

• High-res image generation: Seedream 4.0 generates images with up to 4K resolution, which means you get detailed visuals for digital marketing, artwork, branding, and more.
• Multi-reference and batch generation: It can handle up to ten reference images at once and produce as many as fifteen outputs in a single run.
• Natural language editing: Seedream 4.0 lets you edit text, so you can change images by writing about the changes in plain language. This feature supports background removal, style transformation, and object replacement.
• Image background extension and restoration: This image generation model can recover and refine image details effectively. You can extend the background, restore the details, and even colorize old photos.

Stable Diffusion

Stable Diffusion is an AI model introduced by Stability AI in 2022 and uses a technique called latent diffusion to generate images. You can run it on a regular computer with a good GPU because it's open source.

Features

• Create images from text: You can type a description, and the model will generate an image that lines up with your vision. This works for realistic pictures or artwork.
• Change existing images: You can upload a picture, add a text prompt, and the model will adjust it based on your request. This makes it handy for design tweaks or improving artwork.
• Edit and expand images: The model can change parts of an image (inpainting) or make the image bigger by adding more to its edges (outpainting).
• Open and customizable: Anyone can use and change Stable Diffusion. You can train it on your own images or add it to different apps.
