Generate Images with Realistic Inpainting using Simbrams Ri AI

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.
