HANGZHOU, China—Tuya Smart (NYSE: TUYA; HKEX: 2391), a global AI cloud platform service provider, announced the public launch of Tuya Cobuilder, an AI engineering workspace for smart products. With Tuya Cobuilder, developers can simply describe a product idea in natural language. The platform then generates everything required to bring it to life—product definition, feature recommendations, app panel development, firmware, and AI agent configuration with cloud connectivity. The result: AI hardware that goes from concept to working device in one workflow.

Beyond AI Coding: The Real Bottleneck in AI Hardware

AI coding tools can now turn a single prompt into a working demo. But in AI hardware, code is only a fraction of the challenge. A smart device must also connect reliably, present a usable app interface, stay in sync with the cloud and app, support OTA updates, and remain secure at a global scale.

Individually, these problems are manageable. Together, they form the most time-consuming and failure-prone part of AI hardware development, and they sit entirely outside what AI coding tools address. Traditionally, building this operational foundation has meant months of work by an experienced engineering team, manually aligning every layer of the product stack.

How Tuya Cobuilder Works

Tuya Cobuilder changes the model: instead of engineers manually assembling the runtime, AI builds the entire product operating system automatically. For example, a developer who wants to build an AI pet feeder that chats with its owner simply describes the idea. Tuya Cobuilder then generates the device capability definitions, the app control panel, the AI agent behind the product, the firmware, and the production materials—drawing on the accumulated capabilities of the Tuya AI development platform—and brings up a working physical prototype. Work that once took an engineering team two to three months can be completed by a single product manager in an afternoon.

The key difference from AI coding tools lies in what happens after generation. A working prototype only comes together when multiple layers work in unison: the device must have the right capabilities and connectivity, the app must offer an interactive control panel, the cloud must manage devices, data, and state, and the AI agent must understand the device's functions and act on them at the right moment. Tuya Cobuilder ties these layers together through one unified product definition—generating app panels, configuring device capabilities, assisting firmware development, and linking cloud-based agents to real hardware.

Opening AI Hardware Development to More Builders

Tuya Cobuilder is designed for a broad range of users, not only embedded engineers:

• Independent developers and small teams can turn ideas into working prototypes faster than ever before.

• Device manufacturers and ODMs can accelerate AI upgrades of existing products, adding agent interaction, natural-language control, and automated workflows.

• AI startups with model or agent capabilities can connect software-based agents to real devices and real-world scenarios.

In zero-code or low-code mode, users describe their needs in natural language, and Tuya Cobuilder handles the full journey from product definition to live device integration—no prior expertise in hardware development, cloud APIs, or app engineering required.

Built on Years of AI+IoT Infrastructure

What makes this possible is cross-layer consistency across device, cloud, agent, and app—a capability built on Tuya's years of investment in AI and IoT. From its IoT runtime and global cloud infrastructure to standardized device models, OTA management, runtime orchestration, multi-model routing, and T-RTC real-time communication, these core modules have been refined over time so that hardware, cloud, agents, and apps can operate on a single, stable track.

Tuya Cobuilder is now available at https://www.tuya.com/cobuilder. Every registered account receives free base credits to try the platform, with additional credits available through community events. Developers can register and start building on the Tuya Cobuilder website or the Tuya AI development platform today.
