Generate Images with Realistic Inpainting using Simbrams Ri AI

Description

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.
