Airbnb says AI now writes 60% of its new code

Airbnb said AI-assisted coding has become standard practice inside its engineering organization. Executives told staff that 60% of the new lines committed to the codebase are now generated by AI assistants and reviewed by human engineers before merge. The figure has climbed sharply over the past year inside the San Francisco-based platform, according to internal productivity dashboards.

The lodging company is also extending AI beyond development. A large-language-model-powered support bot now handles 40% of incoming customer requests without ever escalating to a human agent. Airbnb says this has trimmed support operating costs and shortened average resolution times, although it has not disclosed specific dollar savings tied to the deployment.

The disclosure echoes recent statements from Google, Microsoft and Meta, which have reported similar AI authorship rates inside their codebases. While AI coding tools are letting senior engineers offload repetitive work, the trend is fueling concern about slowing hiring at the junior level. Airbnb pushed back on that framing, arguing the technology is not reducing headcount but allowing existing teams to ship product faster.
