Microsoft is reportedly developing an in-house artificial intelligence (AI) reasoning model, aiming to outdo OpenAI and may sell them to developers.
According to The Information, the American tech giant has started testing out models from xAI, Meta, and DeepSeek as potential ChatGPT manufacturer replacements in Copilot.
Microsoft seems to have reduced its dependence on OpenAI, even as its early partnership with the startup solidified its position among Big Tech peers in the evolving artificial intelligence (AI) landscape.
In December, Reuters reported that the Washington-based company is gearing up to add third-party AI models to power its AI product, Microsoft 365 Copilot, to expand from the current underlying technology from OpenAI and eliminate its costs.
When Microsoft revealed 365 Copilot in 2023, a major selling point was that it used OpenAI's GPT-4 model.
It's worth mentioning that the team is reportedly training several other models that utilise chain-of-thought techniques that could compete directly with OpenAI’s.
Suleyman’s team is experimenting with swapping out the MAI models, expanded from earlier Microsoft models called Phi, for OpenAI’s models in Copilot.
The company is reportedly considering launching the MAI models by the end of this year as an application programming interface, enabling outside developers to weave these models into their apps.
