OpenAI, backed by Microsoft, has taken action against a developer who created a bot imitating Congressman Dean Phillips.

The developer has been banned and the account of AI start-up Delphi, which built the bot, was suspended.

This is OpenAI's first action against misuse of its AI tools in a political campaign.

OpenAI has now banned the use of its ChatGPT AI system for political campaigns and lobbying.

The decision led to the shutdown of the Dean.Bot chatbot.

OpenAI's guidelines prohibit potentially abusive use of its technology.

The move comes ahead of the US primary elections in New Hampshire, sparking debate about the use of AI in politics.
