Resolution and size: DALL-E 3 generates images at 1024×1024 pixels, with options for square, portrait, or landscape orientations.
Editing capabilities: DALL-E offers inpainting (selectively editing parts of an image) and outpainting (extending an image beyond its original boundaries).
Prompt complexity handling: DALL-E 3's integration with ChatGPT allows it to interpret complex, conversational prompts with remarkable accuracy. It excels at understanding nuanced requests and generating images that closely match the user's intent.
Midjourney
Technical approach: While Midjourney hasn't disclosed its exact architecture, it uses a diffusion model approach with proprietary modifications that give it its distinctive aesthetic quality.
Resolution and size: Midjourney V5 can generate images up to 1792×1024 pixels and offers various aspect ratios.
Editing capabilities: Midjourney offers more limited direct editing compared to DALL-E, but provides extensive parameter controls for influencing the generation process.
Prompt complexity handling: Midjourney uses a more structured prompt syntax with specific parameters and modifiers. It requires more technical knowledge of its syntax to achieve optimal results but offers precise control through these parameters.
Stable Diffusion
Technical approach: Stable Diffusion is a latent diffusion model that generates images by gradually denoising random patterns in a compressed latent space rather than directly in pixel space.
Resolution and size: Base Stable Diffusion generates at 512×512 or 768×768 pixels, but various implementations and techniques allow for much higher resolutions (4K+) through upscaling and tiling methods.
Editing capabilities: Stable Diffusion offers the most extensive editing capabilities, including inpainting, outpainting, img2img (transforming existing images), and ControlNet for precise control over composition, pose, and other elements.
Prompt complexity handling: Stable Diffusion offers the most granular control through weighted prompts, negative prompts, and various sampling methods, but requires more technical knowledge to master fully.
