Microsoft has rebranded its Bing Chat AI product to Microsoft Copilot, aiming to compete with OpenAI's ChatGPT. Microsoft Copilot is positioned as the free version of the AI chatbot, with a paid option called Copilot for Microsoft 365. The move comes amid the competition between Microsoft and OpenAI, despite their existing partnership. OpenAI recently reported over 100 million active users of ChatGPT in a week. Microsoft has been expanding its presence in the AI space, integrating ChatGPT-like interfaces into its search results and forming strategic alliances, such as with Siemens and Oracle, to leverage generative AI across various sectors.
