Microsoft is rewiring itself for the AI era, on offence and defence

What happened

Microsoft is restructuring its technology and security approach to adapt to the AI era on two fronts. It has begun removing OpenAI’s models from some of its most widely used applications to reduce operational costs. At the same time, Microsoft announced plans to eliminate text-message logins by a set deadline, citing a rise in AI-powered phishing attacks as the main driver.

Why it matters

Pulling OpenAI models from major apps signals Microsoft’s effort to balance AI integration with cost control. Leveraging AI models adds compute expenses, which can escalate quickly at scale. This cutback pressures other software providers to weigh AI’s benefits against rising costs and forces developers to rethink how and when they embed AI capabilities in their products.

On the security side, removing SMS logins acknowledges that AI-generated phishing scams have become too effective and frequent, making SMS authentication a weak link. By ditching SMS-based two-factor authentication, Microsoft is pushing for stronger identity protections, likely increasing adoption of alternatives such as passkeys or app-based authenticators. That shift tightens security but increases infrastructure and user transition costs for businesses relying on legacy login methods.

What to watch next

Operators and developers should monitor how Microsoft’s AI cost cuts affect feature availability and pricing across its app ecosystem. Watch whether this triggers a broader industry reassessment of AI deployment balancing cost and user experience.

Security teams and identity providers need to prepare for a rapid shift away from SMS logins and support for more secure methods, especially as other companies may follow Microsoft’s lead. Emerging AI phishing techniques will redefine where security investments are most needed to prevent credential theft.
