Microsoft shifts toward homegrown AI models to curb rising costs
The software giant is deploying its own AI models in place of expensive third-party services from OpenAI and Anthropic as the industry grapples with ballooning AI expenses.
TechCrunch — AI
Microsoft has joined a growing wave of tech companies cutting AI spending by shifting away from costly third-party models and turning to its own in-house alternatives. The company is now routing a portion of user requests in Excel and Word through its proprietary MAI models instead of the OpenAI and Anthropic systems it previously relied on, according to Bloomberg reporting.
Building Its Own AI Arsenal#
Microsoft has been actively expanding its AI capabilities. At last month's Build conference, the company unveiled seven new MAI models, including an agentic coder and text-to-image tools. This move signals a strategic pivot toward reducing reliance on external vendors and keeping more AI workloads in-house.
The Broader Cost-Cutting Wave#
Microsoft's decision reflects a wider industry shift. After a period of aggressive AI spending earlier this year, major technology firms including Amazon, Uber, Meta, and Accenture have all tightened their AI budgets. The expense of deploying and licensing AI services has become a pressing concern across Silicon Valley, with some companies even exploring cheaper alternatives from Chinese providers—despite potential security risks.
The intensity of these cost pressures has become significant enough that some organizations are scrutinizing how employees use AI tools to prevent budget overruns on routine tasks.
