Chinese Tech Giants Pivot to Infrastructure and Specialized Data as DeepSeek V4 Open-Source Wave Hits

The competitive landscape of the Chinese artificial intelligence sector is undergoing a fundamental structural shift. As top-tier models like the newly released DeepSeek V4 move toward open-source accessibility, the industry’s focus is rapidly pivoting from basic model development to the underlying infrastructure and specialized data required to make AI agents functional in the real world. Tencent Cloud catalyzed this transition earlier this week by open-sourcing “Cube Sandbox,” a critical infrastructure layer designed to run AI agents. The tool, which provides a hardware-isolated execution environment, is compatible with the SDKs used by global leaders like OpenAI and the buzzy AI agent…
