From software interface to venue infrastructure
LiveX said in its November 3 announcement that its AI City platform uses life-size, human-like AI Hosts to provide assistance inside public venues. The company presented the system at Smart City Expo World Congress in Barcelona as an alternative to conventional kiosks, static maps and app-based services.
The strategic appeal is straightforward. Visitors do not need to download an application, scan a QR code or create an account before asking for help. An AI Host can act as a visible service layer for people who are lost, in a hurry or unfamiliar with the venue. That makes the product less dependent on consumer behavior than an app and potentially more scalable than adding staff at every information point.
LiveX said its systems are already deployed at more than 100 customer sites. Those locations include PUMA stores, San José Mineta International Airport, SAP Center, a San Jose Sharks stadium, El Camino Hospital, and Marriott and Hilton hotels. The mix gives the company exposure to several service markets, including retail, travel, healthcare, hospitality and entertainment.
That customer base is strategically important because each sector has a different reason to adopt physical AI. Retailers can use the hosts for product discovery and recommendations. Airports can direct travelers to gates and services. Hospitals can help visitors navigate complex buildings. Hotels can provide multilingual assistance without requiring a guest to find a staffed desk.
A platform, not just a talking display
AI City includes interactive 3D maps for location-aware navigation, product recommendations and multilingual translation. Its Physical AI Host experience is powered by LiveX’s Lyra agent layer, which the company says coordinates speech, expression and movement in real time.
Other components are intended to support multimodal understanding, noise management, visual responses and policy controls. Together, those capabilities position AI City as a venue operating system rather than a single-purpose information terminal. LiveX is attempting to control the full interaction, from understanding a visitor’s question to presenting an answer through voice, motion and visual content.
The commercial value will depend on whether that integration produces better outcomes than cheaper alternatives. A static directory is less engaging but inexpensive and predictable. A mobile app can offer richer personalization but requires installation and user participation. A human employee can handle ambiguity and escalation, but staffing is costly and difficult to scale during surges.
LiveX is therefore competing on availability and convenience. Its example of assisting tens of thousands of sports fans points to the strongest business case: large crowds arriving at the same time, often speaking different languages and asking repetitive questions. If one installation can handle a substantial share of those interactions, venues could reduce pressure on staff while improving access to information.
NVIDIA partnership strengthens the infrastructure story
The platform also gives NVIDIA another path into commercial AI deployments. LiveX said it is using NVIDIA infrastructure and software, including RTX PRO 6000 Blackwell Server Edition GPUs, Metropolis visual AI tools, NVIDIA Cosmos, Nemotron models, retrieval and reranking systems, and Omniverse libraries for digital-twin applications.
For LiveX, that technology stack can support the perception, language and visualization requirements of a physical installation. For NVIDIA, deployments such as AI City broaden the market for accelerated computing beyond data centers and developer workstations. The partnership links LiveX’s customer-facing product to NVIDIA’s broader strategy of supplying the infrastructure behind real-world AI systems.
Yet hardware and software partnerships do not by themselves create a durable competitive moat. LiveX will need to prove that its hosts work consistently in crowded, noisy spaces and can provide directions that are accurate enough for airports and hospitals. It will also need clear procedures for transferring difficult or urgent requests to human employees.
The unresolved trust problem
The announcement does not resolve how visitors will be told what information is captured, how long interactions are retained or whether recommendations are sponsored. Those questions become more consequential in hospitals and airports, where users may be stressed or seeking time-sensitive assistance.
The only outside reaction identified for this report was critical. Fierce Sensors reported that Matt Hamblen questioned whether fixed avatar kiosks qualify as physical AI in the robotics sense, while also raising concerns about capability, governance, accuracy, security and human oversight. No opposing outside view was identified in the supplied sources.
That skepticism points to the central business test. LiveX does not need its hosts to look human to win customers. It needs them to be dependable, transparent and cheaper or more useful than the combination of signage, apps and staff.
If the company can deliver that standard across more than 100 sites and expand without sacrificing accuracy, AI City could become ordinary infrastructure for high-traffic venues. If it cannot, the installations may remain impressive demonstrations that struggle to justify their operating cost.
Rebeca Smith is not a person. No notebook, no deadlines, no face behind the name — just a byline this newsroom publishes under. Here is the production line underneath it, because a name beside a portrait reads like a journalist, and this one is not one.
The models. Writing: gpt-5.6-luna and qwen3-max. Out on the live web: gpt-5.6-luna and gpt-5.6-terra. Pictures: gpt-image-1 and gpt-image-1-mini. Swap one in the newsroom and this line swaps with it — it is read off the machines, not typed here.
How a story is made
- Research. The searching model reads around the story, pointed at primary sources — the filing, the post, the repository — rather than at somebody else's write-up of them.
- Writing. The writing model drafts it against what was found, at Rebeca Smith's usual length and in Rebeca Smith's usual register.
- The loop. A reviewer reads the draft and sends it back with notes. Then reads it again. A piece can go round several times before it leaves the building.
- Enrichment. A quotation has to appear word for word on the page it is taken from. A chart may only use figures that appear in the source it cites. Whatever fails is dropped, and the reason is kept.
- Fact check. A last pass hunts for claims the article makes and its sources do not.
- A human stop. Sensitive subjects are held for a person to read before publication, and a person can kill any of it at any point.
If that sounds less like a newsroom and more like a factory: quite. It is called Press Factory.
