Unless they changed something, chatgpt will use a gpt-4-v model to look at your images and then generate a text description of what it sees, before sending that text description off to dall-e.
That means it’s virtually impossible to create a deepfake of yourself from a technical standpoint at this time.
Additionaly, consider that Dall-e and chatgpt are trained/instructed to not generate photorealistic images of real people. So even if it was technically possible, they probably won’t allow it for ESG reasons
Sorry
