ComfyUI Node: Flux Pro 1.1 (BFL)

Flux Pro 1.1 (BFL):

FluxPro11_BFL is a sophisticated node designed to generate high-quality images based on textual prompts. It leverages advanced algorithms to interpret and visualize the input text, allowing you to create detailed and vibrant images. The node is particularly beneficial for AI artists looking to transform their creative ideas into visual art with precision and flexibility. By offering a range of customizable parameters, FluxPro11_BFL provides you with the ability to fine-tune the output to match your artistic vision, making it a powerful tool in the digital art creation process.

Flux Pro 1.1 (BFL) Input Parameters:

prompt

The prompt parameter is a string input where you provide the textual description of the image you wish to generate. This is the core input that guides the image creation process, and it supports multiline text to allow for detailed descriptions. The default value is an empty string, and there are no specific minimum or maximum length constraints, but the richness of the prompt can significantly impact the detail and quality of the generated image.

width

The width parameter specifies the width of the output image in pixels. It allows you to define the horizontal dimension of the image, with a default value of 1440 pixels. The minimum value is 256 pixels, and the maximum is 1440 pixels. Adjusting this parameter affects the aspect ratio and resolution of the final image.

height

Similar to the width, the height parameter determines the vertical dimension of the output image in pixels. It also has a default value of 1440 pixels, with a minimum of 256 pixels and a maximum of 1440 pixels. This parameter, in conjunction with the width, defines the overall size and aspect ratio of the image.

prompt_upsampling

The prompt_upsampling parameter is a boolean that, when enabled, enhances the resolution of the image based on the prompt details. Its default value is False. Enabling this option can lead to more detailed and refined images, especially when working with complex prompts.

safety_tolerance

The safety_tolerance parameter is an integer that controls the level of safety filtering applied to the generated image. It ranges from 1 to 6, with a default value of 2. This parameter helps manage the content safety of the output, ensuring that the generated images adhere to acceptable standards.

output_format

The output_format parameter allows you to choose the file format for the output image. It offers two options: jpeg and png, with jpeg being the default. This choice affects the image quality and file size, with png typically providing higher quality and larger file sizes.

seed

The seed parameter is an optional integer that sets the random seed for the image generation process. Its default value is -1, which means a random seed is used. Specifying a seed value allows for reproducibility, enabling you to generate the same image from the same prompt and settings.

Flux Pro 1.1 (BFL) Output Parameters:

generated_image

The generated_image is the primary output of the FluxPro11_BFL node. It is the visual representation of the input prompt, created based on the specified parameters. This output is crucial as it embodies the transformation of textual ideas into a tangible visual format, allowing you to evaluate and utilize the generated art in various creative projects.

Flux Pro 1.1 (BFL) Usage Tips:

• Experiment with different prompt descriptions to see how variations in text can lead to different artistic interpretations and outcomes.
• Use the width and height parameters to adjust the aspect ratio and resolution of your image, ensuring it fits your intended use, whether for digital display or print.
• Enable prompt_upsampling for more detailed images, especially when working with intricate prompts that require high resolution.
• Adjust the safety_tolerance to balance between creative freedom and content safety, depending on the context and audience of your artwork.

Flux Pro 1.1 (BFL) Common Errors and Solutions:

"Invalid prompt input"

• Explanation: This error occurs when the prompt parameter is left empty or contains unsupported characters.
• Solution: Ensure that the prompt is a valid string with meaningful content. Avoid using special characters that might not be supported.

"Image dimensions out of range"

• Explanation: This error is triggered when the width or height parameters are set outside the allowed range of 256 to 1440 pixels.
• Solution: Adjust the width and height values to fall within the specified range to ensure proper image generation.

"Unsupported output format"

• Explanation: This error arises when an invalid option is selected for the output_format parameter.
• Solution: Choose either jpeg or png as the output format to resolve this issue.
