When many enterprises weren’t even fascinated with agentic behaviors or infrastructures, Reserving.com had already “stumbled” into them with its homegrown conversational advice system.
This early experimentation has allowed the corporate to take a step again and keep away from getting swept up within the frantic AI agent hype. As a substitute, it’s taking a disciplined, layered, modular method to mannequin growth: small, travel-specific fashions for reasonable, quick inference; bigger giant language fashions (LLMs) for reasoning and understanding; and domain-tuned evaluations constructed in-house when precision is vital.
With this hybrid technique — mixed with selective collaboration with OpenAI — Reserving.com has seen accuracy double throughout key retrieval, rating and customer-interaction duties.
As Pranav Pathak, Reserving.com’s AI product growth lead, posed to VentureBeat in a brand new podcast: “Do you build it very, very specialized and bespoke and then have an army of a hundred agents? Or do you keep it general enough and have five agents that are good at generalized tasks, but then you have to orchestrate a lot around them? That's a balance that I think we're still trying to figure out, as is the rest of the industry.”

Shifting from guessing to deep personalization with out being ‘creepy’
Advice techniques are core to Reserving.com’s customer-facing platforms; nevertheless, conventional advice instruments have been much less about advice and extra about guessing, Pathak conceded. So, from the beginning, he and his staff vowed to keep away from generic instruments: As he put it, the worth and advice ought to be based mostly on buyer context.
Reserving.com’s preliminary pre-gen AI tooling for intent and subject detection was a small language mannequin, what Pathak described as “the scale and size of BERT.” The mannequin ingested the shopper’s inputs round their downside to find out whether or not it could possibly be solved by means of self-service or bumped to a human agent.
“We started with an architecture of ‘you have to call a tool if this is the intent you detect and this is how you've parsed the structure,” Pathak defined. “That was very, very similar to the first few agentic architectures that came out in terms of reason and defining a tool call.”
His staff has since constructed out that structure to incorporate an LLM orchestrator that classifies queries, triggers retrieval-augmented era (RAG) and calls APIs or smaller, specialised language fashions. “We've been able to scale that system quite well because it was so close in architecture that, with a few tweaks, we now have a full agentic stack,” mentioned Pathak.
Because of this, Reserving.com is seeing a 2X improve in subject detection, which in flip is liberating up human brokers’ bandwidth by 1.5 to 1.7X. Extra matters, even sophisticated ones beforehand recognized as ‘other’ and requiring escalation, are being automated.
In the end, this helps extra self-service, liberating human brokers to give attention to prospects with uniquely-specific issues that the platform doesn’t have a devoted device circulate for — say, a household that’s unable to entry its lodge room at 2 a.m. when the entrance desk is closed.
That not solely “really starts to compound,” however has a direct, long-term influence on buyer retention, Pathak famous. “One of the things we've seen is, the better we are at customer service, the more loyal our customers are.”
One other latest rollout is personalised filtering. Reserving.com has between 200 and 250 search filters on its web site — an unrealistic quantity for any human to sift by means of, Pathak identified. So, his staff launched a free textual content field that customers can sort into to right away obtain tailor-made filters.
“That becomes such an important cue for personalization in terms of what you're looking for in your own words rather than a clickstream,” mentioned Pathak.
In flip, it cues Reserving.com into what prospects truly need. For example, scorching tubs — when filter personalization first rolled out, jacuzzi’s had been one of the crucial widespread requests. That wasn’t even a consideration beforehand; there wasn’t even a filter. Now that filter is reside.
“I had no idea,” Pathak famous. “I had never searched for a hot tub in my room honestly.”
In relation to personalization, although, there’s a effective line; reminiscence stays sophisticated, Pathak emphasised. Whereas it’s essential to have long-term recollections and evolving threads with prospects — retaining data like their typical budgets, most well-liked lodge star rankings or whether or not they want incapacity entry — it should be on their phrases and protecting of their privateness.
Reserving.com is extraordinarily aware with reminiscence, in search of consent in order to not be “creepy” when amassing buyer data.
“Managing memory is much harder than actually building memory,” mentioned Pathak. “The tech is out there, we have the technical chops to build it. We want to make sure we don't launch a memory object that doesn't respect customer consent, that doesn't feel very natural.”
Discovering a steadiness of construct versus purchase
As brokers mature, Reserving.com is navigating a central query going through all the business: How slim ought to brokers turn out to be?
As a substitute of committing to both a swarm of extremely specialised brokers or just a few generalized ones, the corporate goals for reversible selections and avoids “one-way doors” that lock its structure into long-term, expensive paths. Pathak’s technique is: Generalize the place potential, specialize the place mandatory and maintain agent design versatile to assist guarantee resiliency.
Pathak and his staff are “very mindful” of use instances, evaluating the place to construct extra generalized, reusable brokers or extra task-specific ones. They attempt to make use of the smallest mannequin potential, with the best stage of accuracy and output high quality, for every use case. No matter may be generalized is.
Latency is one other essential consideration. When factual accuracy and avoiding hallucinations is paramount, his staff will use a bigger, a lot slower mannequin; however with search and proposals, person expectations set velocity. (Pathak famous: “No one’s patient.”)
“We would, for example, never use something as heavy as GPT-5 for just topic detection or for entity extraction,” he mentioned.
Reserving.com takes a equally elastic tack in relation to monitoring and evaluations: If it's general-purpose monitoring that another person is best at constructing and has horizontal functionality, they’ll purchase it. But when it’s cases the place model pointers should be enforced, they’ll construct their very own evals.
In the end, Reserving.com has leaned into being “super anticipatory,” agile and versatile. “At this point with everything that's happening with AI, we are a little bit averse to walking through one way doors,” mentioned Pathak. “We want as many of our decisions to be reversible as possible. We don't want to get locked into a decision that we cannot reverse two years from now.”
What different builders can be taught from Reserving.com’s AI journey
Reserving.com’s AI journey can function an essential blueprint for different enterprises.
Trying again, Pathak acknowledged that they began out with a “pretty complicated” tech stack. They’re now in an excellent place with that, “but we probably could have started something much simpler and seen how customers interacted with it.”
Provided that, he supplied this beneficial recommendation: In case you’re simply beginning out with LLMs or brokers, out-of-the-box APIs will just do effective. “There's enough customization with APIs that you can already get a lot of leverage before you decide you want to go do more.”
Then again, if a use case requires customization not obtainable by means of a typical API name, that makes a case for in-house instruments.
Nonetheless, he emphasised: Don't begin with the sophisticated stuff. Sort out the “simplest, most painful problem you can find and the simplest, most obvious solution to that.”
Establish the product market match, then examine the ecosystems, he suggested — however don’t simply rip out previous infrastructures as a result of a brand new use case calls for one thing particular (like transferring a complete cloud technique from AWS to Azure simply to make use of the OpenAI endpoint).
In the end: “Don't lock yourself in too early,” Pathak famous. “Don't make decisions that are one-way doors until you are very confident that that's the solution that you want to go with.”
