OpenAI has expanded access to its ChatGPT Search feature, making it available to all users, including those on the free tier, as part of its '12 Days of OpenAI' initiative. Previously limited to paying subscribers, this update allows users globally to utilize ChatGPT's AI-powered web search capabilities across its apps and website. The rollout, which began on December 16, includes enhancements such as faster search results, improved mobile usability, and the integration of maps for local searches. Additionally, the search function now supports real-time information retrieval through advanced voice mode, although this feature remains exclusive to paid users. This move is seen as a direct challenge to Google's dominance in the search engine market.
