At Nablai, we build on Tuya T5E, Espressif ESP32S3 and PY32, and offer three product family codes: TY, LX and NT. According to Guangdong province's Action Plan for Accelerating AI Adoption in the Toy Industry (2025-2027), AI toy penetration across the province is to exceed 30% by 2027, with revenue at above-scale toy enterprises reaching RMB 100 billion - which means that over the next two years a great many toy factories will have to make an AI platform decision. And the first step in that decision usually stalls on the plainest question of all: of TY, LX and NT, which one should you pick? What we deliver has never been a bare chip - it is the complete AI toy solution: AI module + Nablai app + cloud services.
Start with three questions
Question 1: Do you need to reach overseas markets fast? If your target markets are Europe, the US or Southeast Asia and your team has no experience with overseas compliance or multilingual support, the TY Series (based on Tuya T5E) is close to a no-brainer: it ships with GDPR / COPPA / CCPA pre-compliance, supports 60+ languages, has global data centers ready to go, and can get you to a shipping product within three months. Quite a few of our customers in export plush toys and IP figures are won over by this point alone.
Question 2: Do you need your own brand and your own user data? If you want your own app, your own account system and your own content operations fully in your hands, then the LX Series (based on Espressif ESP32S3) is where you end up. It comes with the Nablai app and the AMS vendor management platform, with accounts, subscriptions, content and data 100% owned by the brand owner, and it supports integration of a private LLM - the route for full ownership and deep customization. For a factory trying to move from contract manufacturing to building its own brand, this line determines whether you will be able to reach users directly in the future.
Question 3: Do you just want a low-cost trial run? If you are still on the fence about AI voice interaction, your budget is tight, and you simply want to validate the market first, the NT Series (based on PY32) drives cost to the floor with a pure UART command module - the lowest barrier to entry of the three families. It does not connect to the internet and does not run an LLM, but it can make a toy move and make noise, letting you test consumer reaction at the lowest possible cost.
One architectural distinction to get straight
TY002 and LX002 both sit on the same "local SDK + cloud API" dual stack: the local SDK handles firmware, audio capture and servo control, while the cloud API handles LLM inference, content updates and user data. The difference between them lies in ecosystem ownership and brand sovereignty (TY rides on Tuya; LX ships with the Nablai app and the AMS private cloud) - it is absolutely not a case of "API vs SDK, two parallel options". NanoToy (PY32) is the true pure-UART command module: no semantics, no cloud, no SDK, built for low-cost trial runs.
Many customers start out assuming that "TY is cloud-based and LX is local", and that is wrong. Both families are dual-stack; the difference is ecosystem ownership and brand sovereignty, not one architecture being more advanced than the other. Get this straight and your selection will not go off track, and you will not be dragged down by architectural baggage during later integration.
How we route customers
When we start working with a customer, we first ask them to fill in a deliberately minimal requirements form: target market, whether they need to own their data, time to market, budget range. We then give a recommendation against the three families. Quite a few customers go with a combination - "TY leads, LX builds the long-term brand": TY validates overseas demand quickly, and once that works, LX is used to accumulate their own user assets. Delivering the AI module, Nablai app and cloud services as one integrated package makes that switching path very cheap.
The decision tree in shorthand
- Need to go overseas fast → TY (Tuya T5E)
- Need brand ownership → LX (Espressif ESP32S3)
- Need a low-cost trial run → NT (PY32)
- Need overseas reach and ownership → TY first, then LX
The cost line that is easy to miss
On the surface, selection looks like "which module do I buy"; in reality it is "who builds the app afterwards, who runs the cloud, who handles compliance". Buy only a bare chip and the toy factory has to put together an AI team of its own, with a very long integration cycle and very high hidden costs. That is why our unit of delivery is the complete solution rather than a single piece of hardware - this is the line item most worth getting right in a selection decision.
FAQ
Q: Can the three families be mixed? A: Yes. Many of our customers use TY to validate overseas markets and LX to build up their brand, and delivering the AI module, Nablai app and cloud services as one package keeps switching costs low.
Q: How far does deep customization on LX go? A: From the wake word, character personality and expression pack to private LLM integration, everything on the LX Series can be customized per project, with the AMS backend managing devices, users, content and data in one place.
Q: Is NT a cut-down version? A: It is not a cut-down version, it is a different position. NT targets cost-sensitive customers who want to start with a UART command module: it does the job of "a toy that moves and makes noise" as cheaply as it can possibly be done.
Three pitfalls we have helped customers climb out of
The first pitfall is an architectural assumption: one customer believed TY was purely cloud and LX purely local, built a separate design for each, and only at integration discovered that both are dual-stack and the logic was duplicated - about three weeks wasted. The second is buying a bare chip with no app and no cloud: the toy factory had to assemble an AI team on the fly and stalled for two months on compliance and multilingual support alone. The third is running an NT trial, going straight to mass production and distribution, but leaving no data interface for a later migration to LX - which means rework once it is time to move to full brand ownership. All three come down to the same thing: not treating the complete solution as the unit of delivery.
A recommended order for factories making the choice
Decide the market first (domestic or overseas), then data sovereignty (do you need your own accounts and content), and only then budget and schedule. Do not reverse the order - plenty of people look at price first, then discover on launch that there is no pre-compliance, or that the data interface for a move to LX is missing. Our delivery standard for customers is: AI module + Nablai app + cloud services delivered in one shot, an overseas prototype in three months, and brand ownership plus data ownership settled before mass production.
In closing: choosing is really about getting one calculation right
We have seen too many factories treat selection as "which module to buy" and then get dragged down later by the three mountains of app, cloud and compliance. The real calculation is: who builds the app afterwards, who runs the cloud, who handles compliance. Buying only a bare chip means the toy factory has to build its own AI and cloud team, with an integration cycle measured in months and hidden costs far above those of a complete solution. That is why our unit of delivery has been "AI module + Nablai app + cloud services" from the very beginning, not a single piece of hardware. Get this calculation right and the choice stops being agonizing.
