ComfyUI Node: FLUX 1.1 [ultra]

FLUX 1.1 [ultra]:

FLUX 1.1 [ultra] is a powerful node designed to generate high-quality images based on textual prompts. It leverages advanced AI models to interpret and transform your creative ideas into visual art. This node is particularly beneficial for AI artists looking to explore and expand their creative boundaries, as it provides a seamless way to convert descriptive text into detailed and vibrant images. The main goal of FLUX 1.1 [ultra] is to offer a robust and flexible tool that can handle a variety of artistic styles and preferences, making it an essential component for any digital artist's toolkit.

FLUX 1.1 [ultra] Input Parameters:

prompt

The prompt parameter is a required input that allows you to specify the textual description of the image you wish to generate. This parameter is crucial as it directly influences the content and style of the resulting image. The prompt can be multiline, enabling you to provide detailed and complex descriptions to guide the image generation process.

image_prompt

The image_prompt is an optional parameter that lets you provide an existing image to influence the generated output. This can be particularly useful if you want the generated image to maintain certain visual elements or styles from the provided image. The image is converted to a base64 format for processing.

aspect_ratio

The aspect_ratio parameter allows you to define the dimensions of the generated image. By default, it is set to "1:1", but you can adjust it to fit your specific needs, ensuring the output matches your desired composition.

raw

The raw parameter is a boolean option that, when enabled, outputs the raw image data without any post-processing. This can be useful if you want to apply your own custom processing techniques. The default value is False.

safety_tolerance

The safety_tolerance parameter controls the level of safety filtering applied to the generated image. It ranges from 1 to 5, with a default value of 5, ensuring that the output adheres to safety standards and guidelines.

seed

The seed parameter is an integer that sets the random seed for the image generation process. By default, it is set to 0, which means the process is non-deterministic. Setting a specific seed allows for reproducibility of results.

image_prompt_strength

The image_prompt_strength parameter is a float that determines the influence of the image_prompt on the final output. It ranges from 0.0 to 1.0, with a default value of 0.5, allowing you to balance between the textual prompt and the image prompt.

output_format

The output_format parameter specifies the format of the generated image. By default, it is set to "png", but you can choose other formats depending on your requirements.

api_key_override

The api_key_override is an optional string parameter that allows you to specify a different API key for authentication purposes. This can be useful if you need to switch between different accounts or access levels.

FLUX 1.1 [ultra] Output Parameters:

CONDITIONING

The CONDITIONING output parameter provides the processed conditioning data that encapsulates the influence of the input parameters on the image generation process. This data is crucial for understanding how the input prompts and settings have been interpreted and applied by the model to produce the final image.

FLUX 1.1 [ultra] Usage Tips:

• Experiment with different prompt descriptions to explore a wide range of artistic styles and themes. The more detailed and specific your prompt, the more control you have over the generated image.
• Use the image_prompt parameter to incorporate elements from existing images, allowing you to blend new creations with familiar styles or motifs.
• Adjust the image_prompt_strength to fine-tune the balance between the textual and image prompts, giving you greater flexibility in achieving your desired artistic outcome.

FLUX 1.1 [ultra] Common Errors and Solutions:

"Invalid API Key"

• Explanation: This error occurs when the provided API key is incorrect or has expired.
• Solution: Verify that the API key is correct and active. If necessary, update the api_key_override parameter with a valid key.

"Image Prompt Not Found"

• Explanation: This error indicates that the specified image_prompt file could not be located or accessed.
• Solution: Ensure that the image file path is correct and that the file is accessible. Check for any typos or permission issues.

"Invalid Aspect Ratio"

• Explanation: This error arises when the aspect_ratio parameter is set to an unsupported value.
• Solution: Use a valid aspect ratio format, such as "1:1" or "16:9", to ensure compatibility with the node's processing capabilities.
