DALL·E 2 is an AI image generator built by OpenAI that allows users to create realistic images from natural language text prompts, trained on billions of text-image pairs. It can comprehend concepts like dogs, deerstalker hats, and dark moody lighting, enabling it to understand complex prompts and generate matching images. The tool operates using a credit system, with 115 credits costing $15, offering four image variations per prompt. To get the most out of DALL·E 2, users need to learn how to write good prompts, being specific and detailed can improve results, while descriptors and styles can enhance outcomes. DALL·E 2 also offers advanced features like inpainting and outpainting for editing images. The tool is accessible through a web app, with a free trial period that has ended, and users need to buy credits to use it. Users own the generated images, but they come with a multicolored watermark. DALL·E 2 connects to Zapier, allowing users to integrate AI-generated images into their business workflows and automate tasks.
