Microsoft CEO Reveals 30% of Company's Code is AI-generated

2025-04-30

During Meta's LlamaCon conference, Microsoft CEO Satya Nadella engaged in a fireside chat with Meta CEO Mark Zuckerberg. He revealed that 20% to 30% of Microsoft's codebase is now being written by artificial intelligence.

When Zuckerberg inquired about the current percentage of AI-generated code at Microsoft, Nadella provided this figure. He highlighted that the effectiveness of AI-generated code varies across programming languages, with significant progress seen in Python but less advancement in C++.

Microsoft CTO Kevin Scott has previously stated that he anticipates 95% of code will be AI-generated by 2030.

When Nadella turned the question back to Zuckerberg, the Meta CEO admitted he was unsure about the proportion of AI-generated code within Meta.

In last week's Google earnings call, CEO Sundar Pichai mentioned that AI is responsible for generating over 30% of the company's code. However, it remains unclear how precisely Microsoft and Google measure AI-generated code, so these figures should be viewed with some skepticism.
