Hunyuan 3 Generate (Large Budget) Input Parameters:

model

The model parameter specifies the machine learning model used for image generation. It determines the underlying architecture and capabilities of the image generation process. Selecting an appropriate model is crucial as it directly impacts the quality and style of the generated images. There are no specific minimum or maximum values, but the choice of model should align with your project requirements.

prompt

The prompt parameter is a textual description that guides the image generation process. It serves as the creative input, allowing you to specify the desired content and style of the output image. The prompt's clarity and detail can significantly influence the final result, making it essential to craft it thoughtfully. There are no strict constraints on length, but a well-defined prompt can lead to more accurate and visually appealing images.

seed

The seed parameter is a numerical value that initializes the random number generator used in the image generation process. It ensures reproducibility, allowing you to generate the same image multiple times by using the same seed value. The seed can be any integer, and changing it will result in different variations of the generated image.

steps

The steps parameter defines the number of iterations the model will perform during the image generation process. More steps generally lead to higher quality images, as the model has more opportunities to refine the output. However, increasing the number of steps also requires more computational resources and time. There is no fixed minimum or maximum, but balancing quality and resource availability is key.

resolution

The resolution parameter specifies the dimensions of the generated image, typically in pixels. Higher resolutions result in more detailed images but require more computational power and memory. It's important to choose a resolution that meets your project's needs while considering the available resources to avoid potential memory issues.

guidance_scale

The guidance_scale parameter controls the influence of the prompt on the image generation process. A higher guidance scale means the model will adhere more closely to the prompt, while a lower scale allows for more creative freedom. Adjusting this parameter can help achieve the desired balance between prompt fidelity and artistic expression.

post_action

The post_action parameter determines the model's state after image generation. Options include "keep_loaded" to retain the model in memory for subsequent tasks or "full_unload" to release resources. This parameter helps manage resource usage, especially in environments with limited computational capacity.

enable_prompt_rewrite

The enable_prompt_rewrite parameter is a boolean that, when enabled, allows the system to modify the prompt for potentially improved results. This feature can enhance the image generation process by refining the input prompt, but it may also alter the original intent. It's useful for exploring variations and optimizing outputs.

rewrite_style

The rewrite_style parameter specifies the style of prompt rewriting, offering different approaches to modifying the input prompt. Options may include styles like "none" for no rewriting or other predefined styles that influence the prompt's transformation. This parameter provides flexibility in how the prompt is adjusted.

api_url

The api_url parameter is the endpoint for the API used in the image generation process. It defines the communication path between the node and the external service, ensuring the correct exchange of data. The default value is "https://api.deepseek.com/v1/chat/completions," but it can be customized if needed.

model_name

The model_name parameter identifies the specific model version or variant used for image generation. It allows you to select from different model configurations, each with unique characteristics and performance profiles. The default is "deepseek-chat," but other options may be available depending on the system setup.

skip_device_check

The skip_device_check parameter is a boolean that, when enabled, bypasses the device compatibility check. This can be useful in environments where device constraints are known and managed manually, but it may lead to errors if the system is not properly configured.

Hunyuan 3 Generate (Large Budget) Output Parameters:

image

The image output parameter is the final generated image based on the provided prompt and input parameters. It represents the culmination of the image generation process, reflecting the model's interpretation of the prompt. The image's quality and style are influenced by the chosen parameters, making it the primary output of interest.

rewritten_prompt

The rewritten_prompt output parameter provides the modified version of the input prompt if prompt rewriting is enabled. It shows how the system adjusted the original prompt to potentially enhance the image generation process. This output is useful for understanding the impact of prompt rewriting on the final result.

status

The status output parameter indicates the completion status of the image generation process. It provides information on whether the process was successful or if any issues occurred. This output helps in diagnosing potential problems and ensuring the process ran smoothly.

trigger

The trigger output parameter is a signal or flag that indicates specific events or conditions during the image generation process. It can be used to trigger subsequent actions or workflows based on the image generation outcome. This output is useful for integrating the node into larger automated systems.

Hunyuan 3 Generate (Large Budget) Usage Tips:

• To achieve the best image quality, experiment with different guidance_scale values to find the right balance between adhering to the prompt and allowing creative freedom.
• Utilize the seed parameter to reproduce specific images or explore variations by changing the seed value for different outputs.

Hunyuan 3 Generate (Large Budget) Common Errors and Solutions:

GPU Out of Memory! Try reducing resolution or enabling offload.

• Explanation: This error occurs when the GPU does not have enough memory to handle the current resolution or computational load.
• Solution: Reduce the image resolution, enable offloading options, or use a model with lower memory requirements to alleviate the memory pressure.

LLM API requires payment. For DeepSeek, add credits at: https://platform.deepseek.com/top_up

• Explanation: This error indicates that the API service requires payment or credits to continue using its features.
• Solution: Add credits to your account at the specified URL or disable prompt rewriting to avoid additional charges.

LLM API error: <error_message>

• Explanation: This error signifies a problem with the API communication, which could be due to network issues or incorrect API settings.
• Solution: Check your network connection, verify the api_url and model_name parameters, and ensure they are correctly configured.
