OpenAI has announced the rollout of new features for ChatGPT, including a search capability available to all logged-in users, including free-tier users. This update, part of OpenAI's '12 Days of OpenAI' initiative, introduces advanced voice search and improved mobile navigation, enhancing the overall user experience. Users can now ask questions in a conversational manner, allowing for more natural interactions. Additionally, OpenAI has launched a dedicated phone line, 1-800-CHATGPT, enabling users to call and interact with ChatGPT, which operates on the GPT-4o mini model with a knowledge cutoff in October 2023. Meanwhile, Google has unveiled its new AI video model, Veo 2, which is positioned as a competitor to OpenAI's Sora, boasting enhanced capabilities for generating videos. This launch is part of Google's broader strategy to enhance its AI offerings, including updates to its Gemini 2.0 model and other tools aimed at improving user engagement and content creation.
