… with a leading AI company. This longtime, very large customer uses 17 Datadog products to enable unified visibility on production workloads at a very large scale. albeit with a user introduction starting in Q3 which we consider in our guidance and which David will speak to. Before I turn it over to David for a financial review, let me offer a few words on our longer-term outlook. There is no change to our overall view that digital transformation and cloud migration are long-term security growth drivers for our business. But we now have an additional growth driver with AI as we help our customers deliver value with this transformative new technology. We are tremendously excited about our opportunities in AI. To summarize where we are and where we're going. First, AI is a tailwind for Datadog today as cloud consumption grows and drives more users of our platform.

We are addressing this with what we call Datadog for AI to observe and secure the AI stack from end to end. This includes GPU monitoring, Agent Observability, Agent Console, Data Observability, AI Guard, and many other products. Finally, our AI research team and our large volume of rich data using critical workflows enable us to conduct groundbreaking research. We have shown some of our work already with the second version of our time series model, TOTO, in May. TOTO version 2 was exciting for two reasons. First, we've shown it to be state-of-the-art on key benchmarks. but more importantly, we've demonstrated for the first time true scalability for time series models, allowing us to target the same improvement path language models have followed since …
