Generate Images with Realistic Inpainting using Simbrams Ri AI

This n8n workflow integrates with Replicate’s simbrams/ri model to generate images. It takes an input image and mask, applies transformations based on your parameters, and returns the final generated output automatically.

📌 Section 1: Trigger & Authentication

⚡ On Clicking ‘Execute’ (Manual Trigger)

• Purpose: Starts the workflow manually.
• Benefit: Useful for testing and running on demand.

🔑 Set API Key (Set Node)

• Purpose: Stores your Replicate API key inside the workflow.
• Benefit: Keeps credentials secure and ensures other nodes can reuse them.

📌 Section 2: Sending the Image Generation Request

🖼️ Create Prediction (HTTP Request Node)

• Purpose: Sends a POST request to Replicate’s API to start generating an image.

• Input Parameters:

  • image: Input image URL
  • mask: Mask image URL
  • seed: Randomness control (for reproducibility)
  • steps: Number of refinement steps
  • strength: Intensity of modification (0–1)
  • blur_mask: Whether to blur the mask edges
  • merge_m_s: Whether to merge mask with source

• Benefit: Gives full control over how the model modifies your image.

🆔 Extract Prediction ID (Code Node)

• Purpose: Extracts the Prediction ID, status, and URL from Replicate’s response.
• Benefit: Required to check the status of the generation later.

📌 Section 3: Polling & Waiting

⏳ Wait (Wait Node)

• Purpose: Pauses the workflow for 2 seconds before rechecking.
• Benefit: Prevents hitting Replicate’s API too quickly.

🔄 Check Prediction Status (HTTP Request Node)

• Purpose: Checks whether the prediction is complete using the stored Prediction ID.
• Benefit: Automates monitoring of job progress.

✅ Check If Complete (If Node)

• Purpose: Decides if the prediction has finished.

• Paths:

  • True → Sends result to processing.
  • False → Loops back to Wait and keeps checking.

• Benefit: Ensures the workflow only ends when a valid image is ready.

📌 Section 4: Processing the Result

📦 Process Result (Code Node)

• Purpose: Cleans up the completed API response and extracts:

  • Status
  • Output (final generated image)
  • Metrics
  • Created & completed timestamps
  • Model name (simbrams/ri)
  • Final image URL

• Benefit: Delivers a structured and ready-to-use result for display, storage, or further automation.
