Our Commentary ​

An LLM-powered ad stack is certainly a novel approach. The focus on understanding conversational intent for relevance is smart, but the "keeping ads separate from answers" part is where the rubber meets the road for user trust. I'm always wary of ads creeping into AI interactions, so the engineering choices here are critical. It's a complex problem to solve well.
