During a notable conversation at LlamaCon 2025, Microsoft CEO Satya Nadella revealed that artificial intelligence is now responsible for generating approximately 20-30% of code within Microsoft’s
repositories. This disclosure came during a candid discussion with Meta CEO Mark Zuckerberg at Meta’s headquarters in Menlo Park.

The conversation, which lasted 30 minutes, began with Zuckerberg’s effusive introduction of Nadella, describing him as the driving force behind “the greatest technology company of all time’s transformation.” This praise appeared to catch Nadella somewhat off guard, prompting a modest acknowledgment.

Zuckerberg shared his own company’s trajectory regarding AI-generated code, projecting that within the next year, artificial intelligence could be responsible for developing approximately half of Meta’s Llama project code. This revelation highlights the rapid integration of AI tools in software development across major tech companies.

The discussion showcased the complementary nature of both companies’ operations, particularly evident when Zuckerberg acknowledged Meta’s limited presence in enterprise technology, an area where Microsoft has established significant dominance.

Nadella drew parallels between the current AI revolution and previous technological transformations, including the emergence of web, mobile, and cloud computing. However, he emphasized a unique characteristic of the AI evolution: the simultaneous advancement of multiple components, including hardware, software, models, and prompting techniques. This concurrent progress is making AI technology both more accessible and more powerful.

The Microsoft CEO also outlined his company’s vision for a
“distillation factory” concept, which aims to convert large-scale AI models into smaller, more specialized versions optimized for specific tasks. This initiative is designed to make AI implementation more practical and cost-effective for Microsoft 365 customers, allowing them to create customized AI agents for their particular needs.

Regarding AI models, Nadella emphasized Microsoft’s flexible approach, supporting both proprietary and open-source solutions based on customer requirements. He highlighted the particular advantages of open models, especially for organizations seeking to customize AI systems with their proprietary data.

The discussion also touched on the evolution of AI applications, with Nadella describing a future where multiple AI agents work in concert through shared protocols, rather than relying on single, comprehensive models to handle all tasks.

This conversation occurred against the backdrop of Microsoft’s recent Work Trend Index report, which envisions a future workplace where employees function as “agent bosses,” managing teams of AI assistants. While the potential impact on engineering workforces wasn’t directly addressed during the discussion, the implications of increased AI-generated code production raise important questions about the changing nature of software development roles.

The integration of AI in code development represents a significant shift in how major tech companies approach software creation. With Microsoft reporting that up to 30% of its code is now AI-generated, and Meta anticipating that half of its Llama development will soon be AI-driven, the industry appears to be at a pivotal moment in the evolution of software development practices.

The strategic alignment between Microsoft and Meta in their approach to AI development, despite their different market focuses, suggests potential opportunities for future collaboration. Their shared vision for the role of AI in code generation and development processes indicates a broader industry trend toward increased reliance on artificial intelligence in software creation.
