📲 AI Multi-Model Telegram Chatbot (n8n + AIMLAPI)

This n8n workflow enables Telegram users to interact with multiple AI models dynamically using #model_id commands. It also supports a /models command to list all available models. Each user has a daily usage limit, tracked via Google Sheets.

🚀 Key Features

• Dynamic Model Selection: Users choose models on-the-fly via #model_id (e.g., #openai/gpt-4o).
• /models Command: Lists all available models grouped by provider.
• Daily Limit Per User: Enforced using Google Sheets.
• Prompt Parsing: Extracts model and message from user input.
• Logging: Logs every request & result into Google Sheets for usage tracking.
• Seamless Telegram Delivery: Responses are sent directly back to the chat.

🛠 Setup Guide

1. 📲 Create a Telegram Bot

• Go to @BotFather
• Use /newbot → Set name & username.
• Copy the generated API token.

2. 🔐 Add Telegram Credentials to n8n

• Go to n8n > Credentials > Telegram API.
• Create a new credential with the BotFather token.

3. 📗 Google Sheets Setup

• Create a Google Sheet named Sheet1.
• Add columns:

  user_id | date | query | result
  

• Share the sheet with your Service Account or OAuth Email (depending on auth method).

4. 🔌 Connect AIMLAPI

• Get your API key from AIMLAPI.
• In n8n > Credentials, add AI/ML API:
  • API Key: your_key_here.

5. ⚙️ Customize Limits & Enhancements

• Adjust daily limits in the Set Daily Limit node.
• Optional:
  • Add NSFW content filtering.
  • Implement alias commands.
  • Extend with /help, /usage, /history.
  • Add inline button UX (advanced).

💡 How It Works

➡️ Command Examples:

1. Start a chat with a specific model:

   #openai/gpt-4o Write a motivational quote.
   

2. Request available models list:

   /models
   

➡️ Workflow Logic:

1. Receives a Telegram message.

2. Switch node checks if the message is /models or a prompt.

3. For /models, it fetches and sends a grouped list of models.

4. For prompts:

   • Checks usage limits.
   • Parses #model_id and prompt text.
   • Dynamically routes the request to the chosen model.
   • Sends the AI's response back to the user.
   • Logs the query & result to Google Sheets.

5. If daily limit exceeded → sends a limit exceeded message.

🧪 Testing & Debugging Tips

• Test via a separate Telegram chat.
• Use Console/Set nodes to debug payloads.
• Always test commands by messaging the bot (not via "Execute Node").
• Validate cases:
  • Missing #model_id.
  • Invalid model_id.
  • Limit exceeded handling.
