Microsoft is accelerating its push to compete with OpenAI, its longtime collaborator, by developing its own powerful AI models and exploring alternatives to power products like Microsoftโs Copilot bot.
Microsoft has developed its own AI โreasoningโ models comparable to models like OpenAIโs o1 and o3-mini, the The Information reports. OpenAI is said to have refused Microsoftโs requests for technical details about how o1 works โ stoking tensions between the firms.
Microsoft has also developed a family of models called MAI that are competitive with OpenAIโs own, Bloomberg reports, and is reportedly considering offering them through an API later this year. Parallel to those efforts, Microsoft is said to be testing alternative AI models from xAI, Meta, Anthropic, and DeepSeek as possible replacements for OpenAI technology in Copilot.
Microsoft, which has invested around $14 billion in OpenAI to date, has looked to hedge its bets in a number of ways, including hiring DeepMind and Inflection co-founder Mustafa Suleyman to lead the tech giantโs AI efforts.
