TuyaOpen

TuyaOpen is an open source framework for building AI agent hardware, released under the Apache 2.0 license. It provides a cross platform C and C++ SDK with a layered design, covering hardware abstraction, operating system abstraction, libraries, services and applications, so firmware can be written once and deployed across chips. Supported targets include Tuya T series Wi Fi and Bluetooth modules, ESP32 and Raspberry Pi. It pairs with Tuya Cloud for remote control, monitoring and over the air updates, and with Tuya's multimodal AI services. It is aimed at students, makers, AI hardware creators and commercial product teams building voice first or multimodal devices. AI features include wake word detection, cloud speech recognition and synthesis, vision with camera frames for visual questions, and MCP support so a model can call sensors and actuators. It integrates models such as ChatGPT, Claude, Gemini, Qwen, Doubao and DeepSeek. A newly released TuyaOpen IDE adds an AI coding agent extension for VS Code and Cursor with build, flash and debug on real hardware. Pricing is per device. The open source tier is free, needs no license and covers local and offline projects. The IoT Connection license is a one time $0.69 per device and adds cloud connection, the Tuya app, pairing and OTA updates. The AI plus IoT license is a one time $1.67 per device and adds the voice pipeline and agent platform, with a fixed free daily allowance of LLM tokens, speech recognition minutes and synthesis characters; usage beyond it is charged per use. Each developer can claim two free device licenses for testing. Volume licensing for enterprises, startups and education is available by contacting sales.
