OMOST generates highly controllable and customized images by manipulating the properties of objects in the scene, such as position, size and direction. But this project only applies to SDXL model.

lllyasviel/Omost: Your image is almost there! (github.com )

Because the Flux model performs well on structured prompts in json format, the complex omost mode can now be simulated by using ollama nodes combined with customized instructions.

At first, I referred to omost's coordinate and distance specification, and set up the concepts of [row, column] coordinates and far-near relationship, and then let the big language model understand it through instructions and reflect it in structured prompts.

After the test, I found that Flux model has a certain understanding of coordinates, but it is not a very strict geometric mapping, so the composition sometimes deviates, but it does test the relative position and distance of scene elements.

My conclusion is that Flux thinks more about relative position, so I choose to use natural language to describe orientation in json format. This can also achieve relatively accurate picture control.

Based on the above, I refer to omost's block description principle and give two json format versions:

1. Version with coordinate positioning.

On the premise of keeping the seed value unchanged, we can see that the girl's hair is turned white accurately without changing the composition.

The workflow basically only uses the Flux Wensheng diagram node and Olama node that come with comfyu, and its essence lies in the instructions for the big language model in Olama node:

1. First, try to expand the sentence with the large language model, and get a relatively detailed prompt.

Your task is to generate high-quality writing suggestions for image prompt words according to the user's input and using natural language that conforms to AI drawing logic, which needs to include the theme direction, stylized suggestions and artistic aesthetic optimization of the creative content. You will follow the following steps:

1. Understand the input and expand it: add concrete and vivid details, and generate text prompts that accurately describe the image content. Must prompt the theme, content, object and its behavior, scene environment, detail description, composition, perspective, color, tone, light and shadow, artistic style, painting techniques, emotional expression and other elements.

2. Reference to artistic style: according to the needs of users, look for painting knowledge, aesthetic theory, painting technology, etc. from their own knowledge base to assist the writing of prompt words. Add style words or artists' names that conform to the theme and content as artistic style guides.

3. Emphasize the aesthetic effect: ensure that the works achieve the best artistic and technical effect, highlight the aesthetic impact and attraction of painting art, and ensure that the works are beautiful, shocking and thought-provoking. Referring to the current global popular painting aesthetic trends, we can get inspiration from the painting styles and creative ideas of Pinterest, MidJourney, civitai and other platforms, and we can also learn from popular culture, movies, TV series, novels, games and lyrics.

4. Polish the text: Use natural language to polish and expand the user's input, and make it more detailed based on the above three steps, while trying to keep the user's original intention.

5. Describe the composition and perspective: Make sure that the prompt contains a description of the composition and perspective. In the absence of such descriptions, analyze the whole text and add appropriate composition and perspective details. The description format should be: "the composition of this picture is ..., and its perspective structure is ...".

6. Describe the main action: ensure that the prompt contains a specific description of the main action. If there is no action description, analyze and add appropriate action description based on the scene and environment to accurately explain the behavior of the subject.

7.Standardize the output of prompt words: answer in English only. Just give me the final result, without any prefix or suffix. There is no need to say "This is a generated text prompt:". Keep it between 250 and 300 tokens.No need to tell me how many token numbers have been used.

The following text is used as input:

2. Secondly, relay with the big language model, understand and polish the prompt words, and output them in json format. Use the following instructions to receive the natural language prompt words obtained in the previous link, and then generate prompt words in json format.

Your task is to understand the input, polish and optimize it, and keep the theme, content, object and behavior, scene environment, detail description, composition, perspective, color, color, light and shadow, artistic style, painting techniques, emotional expression and other elements.Answer in English only. Just give me the final result, without any prefix or suffix. Needless to say, "This is the generated text prompt:".

Please ensure that you follow this coordinate system precisely to achieve accurate positioning of elements within the canvas:

Coordinate Range:
- Row (Vertical Axis): Values range from 1 to 9, increasing from the top edge to the bottom edge of the canvas.
- Column (Horizontal Axis): Values range from 1 to 9, increasing from the left edge to the right edge of the canvas.
Coordinate Format:
- Coordinates should be written in the format [Row, Column]. For example, [5, 5] represents the center of the canvas.
- [1, 1] represents the top-left corner, while [9, 9] represents the bottom-right corner.
Application Examples:
- To place an element in the top-right corner of the canvas, use the coordinates [1, 9].
- To position an element at the bottom center of the canvas, use the coordinates [9, 5].
Distance to Viewer:
- Range: The distance between the element and the viewer is represented by a value ranging from 1 to 10.
  - 1: Represents the closest possible distance, typically used for extreme close-ups.
  - 10: Represents the farthest possible distance, typically used for elements in the extreme background or horizon.
- Application:
  - Elements that are meant to appear very close to the viewer, such as a subject's face in a portrait, should use a value near 1.
  - Background elements, such as distant mountains or sky, should use a value near 10.
