“Probably in 2025, we at Meta, as well as the other companies that are basically working on this, are going to have an AI that can effectively be a sort of midlevel engineer that you have at your company that can write code.”

Mark ZuckerbergCEO

Founder and CEO, Meta Platforms

Coding agents advanced sharply in 2025 and now handle substantial amounts of real engineering work, but no lab — Meta included — fielded a system that autonomously fills a mid-level engineer's role; Meta shipped no such 'AI engineer' product in 2025 and Zuckerberg's own follow-on framing pushed the milestone of AI writing most of Meta's AI code into 2026.
