Graphic template customization using simple text prompts

A non-transitory computer readable medium storing code for implementing document generation, the code comprising instructions executable by at least one processor to perform operations comprising:

• receiving an input graphic design document and an input prompt, wherein the input graphic design document includes an image element, and wherein the input prompt indicates a target theme different from a theme of the input graphic design document;
• generating, using an image generation model, a synthetic image based on the input prompt, wherein the synthetic image has the target theme;
• and
• generating a custom graphic design document based on the input graphic design document and the synthetic image, wherein the custom graphic design document has the target theme and includes the synthetic image at a location of the image element of the input graphic design document.

An apparatus comprising:

• at least one processor;
• at least one memory storing instruction executable by the at least one processor;
• an image generation model comprising parameters stored in the least one memory and trained to generate a synthetic image based on an input prompt, wherein the input prompt indicates a target theme;
• and
• a document generation component configured to generate a custom graphic design document based on the synthetic image and an input graphic design document, wherein the custom graphic design document has the target theme and includes the synthetic image at a location of the image element of the input graphic design document.
