Automate Telegram AI Chatbots with OpenAI Integration

This Telegram bot uses artificial intelligence to provide a dynamic chat interface for users. It listens for messages from Telegram users and generates responses using the OpenAI API, allowing users to ask questions and automate tasks within the chat.

The bot can also generate images based on user prompts using the OpenAI API. If an unsupported command is received, an error message is sent back to the user. This automation is designed to enhance messaging and bot experiences, as outlined in the product builder prompt.
