Text-to-Image (T2I)
Pure T2I models generate an image entirely from your text prompt. They offer the most creative freedom but require more detailed prompting to achieve consistent results. Best for: concept art, backgrounds, illustrations, product mockups without a reference.
Best models: Flux Schnell, Flux Dev, Recraft V4 Pro, GPT Image 2, Imagen 4 Ultra
Image-to-Image (I2I)
I2I models take a source image and modify it according to your text instructions. They preserve structural elements from your input, making them ideal for editing, style transfer, and iterative refinement.
Best models: Flux Kontext Pro, Nano Banana Pro, Recraft V3
