API & SDK

Create a Prediction

Send a POST request to create a new prediction. This will return a prediction ID that you'll use to check the result. The request should include your model inputs and API key.

Get Prediction Result

Poll the prediction endpoint with the prediction ID until the result is ready. The API uses long-polling, so you'll need to repeatedly check until you receive a success status.

Overview

The "post-processing" AI model is an image generator designed to handle advanced image refinement tasks following initial image creation. Developed using modern diffusion-based architectures, it is tailored for scenarios where generated images require further enhancement, correction, or stylistic adjustment. The model is structured around an OpenAPI schema, allowing seamless integration into automated pipelines and supporting a range of post-generation manipulations.

Key features include configurable prompt-based control, support for negative prompts to exclude unwanted elements, and adjustable inference steps for balancing quality and speed. The model leverages state-of-the-art diffusion technology, likely based on architectures such as Stable Diffusion XL, to deliver high-fidelity outputs. Its uniqueness lies in its flexible parameterization, enabling users to fine-tune results for specific creative or technical requirements, and its ability to integrate with broader generative workflows for tasks like upscaling, artifact removal, and style transfer.

Technical Specifications

  • Architecture: Diffusion-based (likely Stable Diffusion XL or similar)
  • Parameters: Not explicitly stated, but typical models in this class range from 1B to 2.3B parameters
  • Resolution: Supports multiple resolutions, with defaults such as "squarehd"; customizable via input parameters
  • Input/Output formats: Accepts structured JSON input with fields for prompt, negativeprompt, imagesize, numinferencesteps, guidancescale, seed, and others; outputs include a list of generated images, timing data, and seed used
  • Performance metrics: Inference step range (1-50), guidance scale (0-20), batch generation (1-4 images per request), and timing information for each generation

Key Considerations

  • Carefully craft prompts for best results; specificity improves output quality
  • Use negative prompts to filter out undesired elements or styles
  • Adjust inference steps: higher values yield better quality but increase processing time
  • Guidance scale controls prompt adherence; higher values make outputs more literal but can reduce creative variation
  • Batch generation is supported but may increase resource usage and latency
  • Consistent seeding ensures reproducible results for the same prompt and settings
  • Sync mode can be enabled for direct image retrieval but increases response latency
  • Monitor resource usage, especially with high-resolution or multi-image requests

Tips & Tricks

  • Start with default inference steps (e.g., 25) and incrementally increase for higher detail if needed
  • Use clear, descriptive prompts and refine iteratively based on output
  • Leverage negative prompts to suppress unwanted features (e.g., "blurry, low resolution, cartoon")
  • For style consistency, specify desired aesthetics explicitly in the prompt
  • Experiment with guidance scale between 7.5 and 12 for balanced creativity and prompt fidelity
  • Use seed values to reproduce or slightly tweak results for batch experimentation
  • For batch tasks, generate multiple images at lower quality first, then upscale or refine the best candidates

Capabilities

  • High-quality image post-processing, including upscaling, artifact removal, and style adjustment
  • Flexible prompt-based control for both inclusion and exclusion of features
  • Batch image generation for rapid prototyping or variant creation
  • Consistent, reproducible outputs with seed control
  • Adaptable to a wide range of creative and technical workflows
  • Supports advanced use cases such as 3D model texture refinement and style transfer

What Can I Use It For?

  • Professional image enhancement in design and advertising workflows
  • Creative projects such as digital art, concept visualization, and illustration refinement
  • Business use cases including product image upscaling, background cleanup, and brand style enforcement
  • Personal projects like photo restoration, meme creation, and hobbyist art improvement
  • Industry-specific applications such as 3D asset post-processing for games, AR/VR content, and architectural visualization

Things to Be Aware Of

  • Some experimental features (e.g., deep cache) may not be fully documented or stable
  • Users have reported that prompt specificity greatly affects output quality; vague prompts yield generic results
  • High-resolution or multi-image requests can significantly increase processing time and resource consumption
  • Consistency across batches is generally strong with fixed seeds, but minor variations can occur due to stochastic sampling
  • Positive feedback highlights the model's flexibility, ease of integration, and quality of post-processed images
  • Common concerns include occasional over-smoothing, loss of fine detail at extreme settings, and the need for manual prompt refinement
  • Resource requirements can be substantial for large-scale or high-fidelity tasks; monitor system load accordingly

Limitations

  • May not perform optimally for highly specialized or niche artistic styles without extensive prompt engineering
  • Not suitable for real-time applications requiring instant feedback due to processing latency, especially at high quality settings
  • Limited by the inherent constraints of diffusion-based architectures, such as occasional artifacts or lack of semantic understanding in complex scenes

Pricing

Pricing Detail

This model runs at a cost of $0.001000 per execution.

Pricing Type: Fixed

The cost remains the same regardless of which model you use or how long it runs. There are no variables affecting the price. It is a set, fixed amount per run, as the name suggests. This makes budgeting simple and predictable because you pay the same fee every time you execute the model.
