ChatGPT Search, OpenAI's AI-powered web search experience, is now live for all ChatGPT users with new features, the company said on Monday.

ChatGPT Search was initially only available for premium ChatGPT subscribers. Now nonpaying users can access it as well.

ChatGPT Search launched in October as an evolution of OpenAI's SearchGPT prototype, unveiled this summer.

Powered by a fine-tuned version of OpenAI's GPT-4o model, ChatGPT Search serves up information from the web along with links to relevant sources, at which point users can ask follow-up questions to refine their search.

ChatGPT Search can be set as the default search engine for any web browser and has been made "faster." ChatGPT Search experience for mobile is also improved, OpenAI said during a livestream Monday.

ChatGPT Search is now available in Advanced Voice Mode, OpenAI's real-time conversational feature for ChatGPT.
