Keep the visual brief attached to the request
The Gen-4 References guide describes using source images for subjects, scenes and visual styles. Reference names can be used in prompts, and several source elements can be combined. This gives a more concrete brief than asking the model to reproduce an unspecified brand style.Gen-4 Image reference controls
Use it to explore a defined set of options
Practical guidance. For early layout options, keep the same references and change one instruction at a time. Compare the resulting images before selecting a final composition. Include the cost of rejected images when comparing Turbo with another model; the price of one successful asset can differ from the price of one request.
