“Product Development expenses also scaled, falling from 9.3% of revenue in Q1’25 to 7.9% in Q1’26. This reflects the deceleration in headcount growth, and the increasing use of AI among our engineers. Gains in productivity mean that we intend to keep engineer headcount broadly stable in 2026”

“Productivity gains across our technology teams are among the most tangible results of our AI investment. Headcount grew 8% YoY in Q1’26 – a carryover effect of 2025 hiring – but productivity KPIs are growing 7-10x faster. Many of our most senior engineers that were previously spending most of their time reviewing code are now also building code because of the productivity gains enabled by AI tools. Rollbacks – code that is returned to its developer due to errors – are materially lower YoY.”

“Generative AI (“GenAI”) adoption at MercadoLibre has continued to expand across the organization. Approximately 95% of our employees have adopted GenAI tools in their work. Internal measurements show that about 30% of the code that reaches production is written with the use of AI.”

“This blended figure reflects differences across our portfolio, where mature, large-scale systems and newer environments show varying levels of AI-generated code. All code written with AI is incorporated through our established development, review, and release processes. During the year, we also observed an approximately 40% increase in merged contributions, which we believe reflects improvements in development velocity and ongoing enhancements to our development processes.”

“For Employee Support, a proprietary GenAI conversational bot handles over 1.4 million annual inquiries, increasing the self-service rate from 70% to 93%.”

“We expect this leverage to be partially offset by the ramp up in our use of third-party AI models. This reflects a deliberate choice to prioritize company-wide adoption over cost optimization at this stage. This investment is contributing to cost efficiency across many other expense lines (customer service, for example) as well as helping us to generate incremental revenue (in Acquiring and Advertising, for example).”

“We rolled out our first AI-powered search experience in our marketplace in Q1’26, shifting the architecture away from keywords and rebuilding it around LLMs. In Brazil and Mexico, the improvement in product relevance led to uplifts in conversion and click-through-rate for sponsored listings, both of which represent incremental revenue. These are early results, which we believe have the potential to transform how our customers search and discover products on our platform.”

“We also use autonomous AI agents to support portions of our engineering work. These agents perform defined tasks such as contributing to code reviews, assisting with documentation, reviewing incidents, and handling certain migration and update activities across parts of our codebase. They operate as part of our broader development workflow and complement the work of our engineering teams.”

“Our vision for GenAI is that everyone at the Company can use it to boost their productivity and accelerate business impact. To solve the various challenges in our operations, MercadoLibre has numerous proprietary AI solutions, and our teams are much more efficient today. We are using AI to assist our employees in the production of TV commercials, handling of customer service cases, and response to legal demands.”
