n8n AI Image Generation with OpenAI & Telegram

n8n AI Image Generation with OpenAI and Telegram is a practical workflow for turning a simple image request into a generated image and automatically delivering and storing the result.

In this workflow, another n8n workflow passes an image title, image prompt, and Telegram chat ID into the automation. An AI agent powered by GPT-4.1 through OpenRouter expands the user's basic image prompt into a detailed, production-ready description covering the subject, setting, visual style, mood, lighting, and additional details.

The workflow then sends that generated prompt to the OpenAI Images API using the gpt-image-1 model to generate a 1024×1024 image.

Once the image is generated, n8n converts the returned base64 image data into a file. The workflow then performs multiple automated actions with the resulting image.

First, the generated image is sent directly to Telegram using the supplied chat ID, allowing the requester to receive the image automatically.

The image is also uploaded to Google Drive using the original image title as the filename. This provides centralized storage for generated AI images.

Finally, the workflow records the generated image in Google Sheets. The log stores the original request, generated image ID, Google Drive link, title, and content type, creating a simple marketing-team image log that can be used to keep track of generated assets.

### Workflow Highlights

• Triggered by another n8n workflow
• Accepts image title, image prompt, and Telegram chat ID
• Uses GPT-4.1 through OpenRouter for detailed image-prompt engineering
• Generates images through the OpenAI Images API
• Uses the gpt-image-1 image generation model
• Generates images at 1024×1024 resolution
• Converts base64 image data into a file
• Sends the generated image to Telegram
• Uploads the image to Google Drive
• Logs image metadata in Google Sheets

### Business Problem Solved

Creating AI images manually often requires repeatedly moving between an AI image generator, file storage, messaging platforms, and tracking spreadsheets. This n8n automation connects those steps into one workflow.

Instead of manually creating an image, downloading it, sending it to a team member, uploading it to storage, and recording the asset information, the workflow handles those steps automatically after receiving the initial request.

### Practical Use Cases

This workflow can be useful for marketing teams, content creators, automation developers, agencies, and businesses that need to generate and organize visual assets as part of an automated content process.

It can also serve as a reusable image-generation sub-workflow that other n8n automations can execute whenever an image needs to be created.
