> DALL-E 2 is not based on GPT-3. Under the hood, it works in two stages. First, it uses OpenAI’s language-model CLIP, which can pair written descriptions with images, to translate the text prompt into an intermediate form that captures the key characteristics that an image should have to match that prompt (according to CLIP). Second, DALL-E 2 runs a type of neural network known as a diffusion model to generate an image that satisfies CLIP.

So, some stages seems to be artificially introduced...
