Microsoft is reshaping its AI strategy for 365 Copilot by integrating in-house and third-party models, easing its reliance on OpenAI due to cost and speed concerns for enterprise users, according to sources.
Microsoft Expands 365 Copilot with Internal and Third-Party AI Models
Reuters, citing persons familiar with the matter, stated that Microsoft 365 Copilot, an AI tool, has been in the process of merging both internal and third-party AI models.
In order to diversify away from OpenAI's present underlying technology and cut expenses, this move is strategically important.
According to the individuals cited in the post, the Satya Nadella-led corporation is also working to reduce 365 Copilot's reliance on OpenAI. This move is driven by concerns around cost and speed for enterprise users.
OpenAI Collaboration Remains Central to Microsoft's AI Product Development
According to a Microsoft representative cited in the article, the tech giant is still working with OpenAI on frontier models. “We incorporate various models from OpenAI and Microsoft depending on the product and experience.”
Reportedly, businesses still have not seen a return on investment from Microsoft 365 Copilot. The amount of licenses sold is something that the tech giant has chosen not to disclose.
GitHub Diversifies AI Offerings Beyond OpenAI Models
This follows the lead of other Microsoft divisions that have modified their usage of OpenAI models. For example, in October, as an alternative to OpenAI's GPT-4, GitHub—which was acquired by Microsoft in 2018—added models from Anthropic and Google, which is a division of Alphabet Inc.
It had been said that Microsoft insiders were worried that their AI approach would be too dependent on their collaboration with OpenAI.
Investment and Strategy Talks Highlight Microsoft's AI Transition
Microsoft and OpenAI met in October to discuss the eventual conversion of Microsoft's $14 billion investment into OpenAI stock.
A December article stated that after OpenAI achieves artificial general intelligence, it intends to eliminate a provision that limits Microsoft's access to its most sophisticated AI models.
Closing at $435.25, Microsoft's stock lost 0.31% on Monday. Shares, however, have increased 17.36% thus far this year, as reported by Benzinga.
