[The 4o image generation model is available both in ChatGPT and in Sora. The following discussion of workflows is based specifically on the ChatGPT conversational model.]
The 4o image generation model works great for "one-shot" image generation -- just tell it what you want and it will go for it. But for larger projects that need multiple images that work well together, a workflow approach will help you get more consistent, repeatable results.
The 4o image model enables real-world, practical applications through its conversation-based design. Workflows are an effective approach for specific use cases that can transform image generation from a fun toy into a serious tool for professional projects.
The concept of "prompting" for image generation originally came from stateless, context-free operations (like API calls). However, 4o image generation works differently—it's conversation-based and maintains state throughout the interaction. That means that images in 4o are generated based on the entire context window of the conversation, not just the immediate request preceding the generation step. This is why thinking in terms of a single "prompt" producing an image doesn't fully capture how 4o's image generation process actually works.
A workflow is simply a set of steps that primes your conversation with clear guidance about what you're trying to accomplish. The more the model understands what you want, the better results you'll get.
For complex real-world applications, workflows help you take advantage of 4o's stateful nature by setting the stage for image generations. You can do this either by having a conversation that primes the context window, or by providing a "spec sheet" at the start of your conversation.
The spec sheet concept comes from art direction for illustration and animation projects. For 4o image generation, it's basically a detailed, reusable system prompt that primes the context window in a new conversation. This approach is similar to how animators work from character and world-building style sheets that define the look and feel of their projects.
Creating Reusable Spec Sheets
Once you've had a conversation that produces an image you're happy with, you can easily create a reusable spec sheet for future projects. Simply ask 4o to write a system prompt based on your successful conversation. Here's an example request:
"I would like to be able to make a series of images in this same style. Please give me a system prompt that I can use to prime future conversations with a specification sheet for images of this type, including the art style details, similar coloration and other details that will help produce more images that will match this look, but possibly with different content."
This approach allows you to capture the essential features of successful generations and apply them consistently to new projects without starting from scratch each time.
For an example of a workflow spec sheet for mokuhanga (Japanese woodblock print) images, especially in the Yakusha-e (Kabuki actor print) style, see: https://discord.com/channels/974519864045756446/1358293638572150794
Spec sheets can be shared easily and modified to customize solutions according to your needs. For character consistency, upload one or more sample images with the spec sheet as a visual reference.
