Multi-Model AI Telegram Chatbot with AIMLAPI & Usage Limits

This n8n workflow creates a powerful Telegram chatbot that enables users to interact with multiple AI models from providers like OpenAI via simple #model_id commands (e.g., #openai/gpt-4o). The /models command lists all available models grouped by provider, while prompt parsing extracts the model and message seamlessly. Every interaction is logged in Google Sheets for tracking, including user queries and AI responses.

Key features include per-user daily usage limits enforced through Google Sheets lookups and updates, preventing overuse and enabling cost control. The workflow handles Telegram webhooks, processes messages intelligently, calls the AIMLAPI for dynamic model inference, and delivers responses directly to the chat. It's robust, scalable, and requires minimal maintenance once set up.

Perfect for customer support bots, community Q&A, personal AI assistants, or internal team tools. Benefits include time savings on custom bot development, centralized usage analytics, flexible model switching without redeploying, and easy integration into existing n8n setups. Customize limits, add NSFW filters, or extend logging effortlessly.

Setup is straightforward: create a Telegram bot via BotFather, configure credentials in n8n, prepare a Google Sheet with user tracking columns, and add your AIMLAPI key. Deploy in minutes for production-ready AI chat automation.
