Create a Multi-Model AI Chatbot with Telegram, AIMLAPI, and Google Sheets

📲 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:

Start a chat with a specific model: #openai/gpt-4o Write a motivational quote. Request available models list: /models ➡️ Workflow Logic:

Receives a Telegram message.

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

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

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.

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.
