AI-Powered Telegram Chat & Image Generation Agent

Unlock Conversational AI & On-Demand Image Generation in Your Telegram Bot

This AI Agent transforms your Telegram bot into a dynamic assistant. It listens to user messages, uses OpenAI's GPT-4o via LangChain for smart, context-aware replies, and can generate DALL-E 3 images on request. Ideal for automating engagement, providing creative content, or streamlining team tasks directly within Telegram.

Key Features & Benefits

• AI-Powered Conversations: Leverages OpenAI's GPT-4o model and LangChain for natural, human-like text responses within Telegram.
• Integrated Image Generation Ability: Employs DALL-E 3 to create and send images directly in the chat. The agent intelligently decides when to use this tool based on user prompts.
• Contextual Memory: Utilizes LangChain's Window Buffer Memory to remember recent parts of the conversation, leading to more coherent and relevant interactions.
• Tool-Equipped Agent: A practical example of a LangChain agent using multiple tools: one for generating images via an HTTP request to OpenAI, and another specific Telegram tool for sending the generated image.
• Customizable Persona: Easily tailor the AI's system prompt within the 'AI Agent' node to define its personality, tone, and specific operational instructions (e.g., addressing users by name).
• Seamless Telegram Integration: Automatically triggers on new Telegram messages and sends text replies or images back to the originating chat, creating an interactive experience.

• An n8n instance (Cloud or self-hosted).
• OpenAI API Key with access to GPT-4o (or a similar powerful model) and DALL-E 3.
• A Telegram Bot Token from BotFather.
• Ensure your n8n instance has LangChain nodes available (usually included in Cloud; for self-hosted, you might need to install the @n8n/n8n-nodes-langchain collection).

1. Download the n8n workflow JSON file.
2. Import the workflow into your n8n instance.
3. Configure the 'Listen for incoming events' (Telegram Trigger) node: Select or create new Telegram API credentials using your Bot Token.
4. Configure the 'OpenAI Chat Model' node: Select or create new OpenAI API credentials. Ensure the model is set to gpt-4o or your preferred compatible model.
5. Configure the 'Generate image in Dalle' (LangChain HTTP Request Tool) node: Select the same OpenAI API credentials as in step 4. Confirm the URL points to the OpenAI image generation endpoint and dall-e-3 is specified as the model.
6. Configure the 'Send back an image' (Telegram Tool) node: Select or create your Telegram API credentials (can be the same as in step 3).
7. Configure the 'Send final reply' (Telegram) node: Select or create your Telegram API credentials (can be the same as in step 3).
8. In the 'AI Agent' node, customize the systemMessage under 'Options' to define your agent's behavior, persona, and how it should interact with users and tools (e.g., how to handle image requests).
9. Verify the sessionKey in the 'Window Buffer Memory' node is dynamic (e.g., chat_with_{{ $('Listen for incoming events').first().json.message.chat.id }}) to maintain separate conversation histories for different users.
10. Activate the workflow. Test by sending messages and image requests to your Telegram bot.
