AI now writes up to 30% of Microsoft’s code: Microsoft CEO

Microsoft CEO Satya Nadella revealed that artificial intelligence now generates up to 30% of the code across the company’s software projects, highlighting a major shift in how modern software is developed.

Speaking at Meta’s LlamaCon AI developer conference alongside Meta CEO Mark Zuckerberg, Nadella said, “I’d say maybe 20%, 30% of the code that is inside of our repos today and some of our projects are probably all written by software,” referring to AI systems.

The two tech leaders discussed the growing role of AI in software development. Nadella noted that AI-assisted coding is gaining traction at Microsoft, with more success seen in languages like Python compared to more complex ones such as C++.

The percentage of AI-generated code is expected to rise steadily.

Zuckerberg did not specify Meta’s own AI coding metrics but said the company is developing AI models that can autonomously build future versions of its Llama AI models.

“Our bet is that in the next year, maybe half the development is going to be done by AI,” he said.

The comments come amid an industry-wide shift.

Google CEO Sundar Pichai recently stated that over 30% of new code at Google is AI-generated.

Microsoft CTO Kevin Scott has previously predicted that 95% of code could be written by AI by 2030.

As tech giants automate more tasks, companies like Shopify and Duolingo have begun requiring proof that humans can outperform AI before justifying new hiring.

The use of AI in software development marks a broader transformation in the global tech workforce and productivity strategies.
