This workflow creates an AI-powered Telegram bot that allows users to generate and modify images using Grok Imagine models via the Kie AI API.

Key Advantages

1. ✅ Multi-Modal Input Support

Users can interact using:

  • Text
  • Voice
  • Images

This makes the bot highly flexible and user-friendly.

2. ✅ Intelligent AI Orchestration

Instead of directly calling APIs, the workflow uses an AI agent that:

  • Understands intent
  • Enhances prompts
  • Chooses the correct tool automatically

This dramatically improves output quality.

3. ✅ Fully Automated Image Pipeline

From user input to final image delivery:

  • Upload
  • Processing
  • Generation
  • Result retrieval
  • Delivery via Telegram

Everything is automated end-to-end.

4. ✅ Asynchronous & Scalable Architecture

The use of:

  • Webhook callbacks
  • Wait nodes
  • Task polling

Prevents timeouts and supports longer image generation tasks.

5. ✅ Secure Access Control

The Telegram ID validation ensures:

  • Only authorized users can access the workflow.

6. ✅ Modular & Extendable Design

The workflow is built with:

  • Tool-based architecture
  • Separate image generation workflows
  • Clear orchestration logic

This makes it easy to extend with:

  • Video generation
  • Style presets
  • Advanced editing tools
  • Multi-user support

7. ✅ Production-Ready Structure

The workflow includes:

  • Error handling guidelines
  • Structured system prompts
  • Memory handling
  • Clear separation of concerns

This makes it suitable for:

  • Creative agencies
  • AI SaaS products
  • Marketing automation
  • Telegram-based AI services

How it works

This workflow creates a Telegram bot that uses AI to generate and transform images through Grok Imagine models, with support for text, voice, and image inputs.

  1. Telegram Input Handling: Users interact with the bot by sending messages, voice notes, or images. The workflow authenticates users based on their Telegram ID.

  2. Input Processing:

    • Text messages → Directly sent to the AI agent
    • Voice messages → Transcribed using OpenAI Whisper, then converted to text
    • Images → Downloaded from Telegram, uploaded to an FTP server (BunnyCDN), and the public URL is generated

  3. AI Agent Decision Making: The "Grok Imagine Agent" (powered by Grok 4.1 Fast model) analyzes user input and determines whether to:

    • Generate a new image from text description (text-to-image)
    • Transform an existing image using a prompt (image-to-image)

  4. Tool Execution: The agent calls specialized workflow tools that trigger image generation via Kie.ai API:

    • Text-to-Image: Creates images from text prompts using "grok-imagine/text-to-image" model
    • Image-to-Image: Modifies existing images using "grok-imagine/image-to-image" model

  5. Async Processing: The workflow uses Wait nodes to handle asynchronous image generation, polling Kie.ai for results via task IDs.

  6. Result Delivery: Once images are generated, they're sent back to the user through Telegram messages.

Setup Steps

  1. Telegram Configuration:

    • Create a Telegram Bot via BotFather to get a bot token
    • Add your Telegram user ID in the "Code" node (replace XXX)
    • Configure Telegram credentials in n8n with your bot token

  2. API Credentials:

    • OpenRouter: Sign up at OpenRouter.ai, get API key for Grok 4.1 Fast access
    • Kie.ai: Register at Kie.ai for free API key to access image generation models
    • OpenAI: Set up OpenAI API key for voice transcription (Whisper model)

  3. FTP Server Setup:

    • Configure FTP server (BunnyCDN recommended) for image hosting
    • Update FTP credentials in n8n
    • Set the public URL path in the "Set Image Url" node (replace XXX)

  4. Workflow Configuration:

    • Import the JSON workflow into n8n
    • Update all credential references to match your accounts
    • Verify webhook URLs are properly configured for callback handling
    • Test the workflow and activate when ready

  5. Optional Customizations:

    • Adjust the system prompt in the "Grok Imagine Agent" node for different behavior
    • Modify image aspect ratios or other parameters in the HTTP Request nodes
    • Add additional tools for more functionality
