AI Image Editor & Generator
Type a prompt, attach references, and generate or transform any image — across 4 AI models in one workspace. No design experience needed.
Generate or Edit Any Image in 3 Steps
Describe the output you want, select a model, and download the result in seconds.
Write a Prompt — Attach References Optionally
Describe what you want created or transformed in plain text. Attach reference images to steer style, composition, or subject identity.
Choose the Right AI Model
Match the model to the task: Nano Banana 2 for broad 4K generation, Flux 2 Pro for high-fidelity transformation, GPT-4o for complex layered instructions, Grok Imagine for distinctive creative output.
Download and Iterate
Results are ready at up to 4K in seconds. Not quite there? Adjust the prompt or switch models — each comparison takes seconds, not minutes.
What is the AI Image Editor and Generator?
The AI Image Editor generates, transforms, and refines images from plain-English instructions and optional reference photos. Instead of working through layers, curves, and brush tools in a traditional editor, you describe the result you want and the AI executes it in seconds.
HappyHorse puts four AI models — Nano Banana 2 (Google Gemini), Flux 2 Pro (Black Forest Labs), GPT-4o Image (OpenAI), and Grok Imagine (xAI) — into a single unified workspace. Each model has distinct strengths: Nano Banana 2 covers 15 aspect ratios at up to 4K for broad generative work; Flux 2 Pro preserves image quality during transformation; GPT-4o executes complex, multi-step prompt instructions; Grok Imagine produces visually distinct creative styles.
The multi-model architecture means you are never locked into one AI's limitations. Run the same brief across models, compare outputs, and select the strongest result for each task.
