Tencent open-sources Hy4 preview, an enterprise-first 770B model
Tencent just open-sourced Hy4 preview, a 770B-parameter MoE model (49B active) with a 1M context window tailored for real-world coding, finance, and scientific tasks. Crucially, the model helped train itself through a recursive self-improvement loop for data strategy and kernel optimization. It is already rolling out across Tencent products like Yuanbao and CodeBuddy.
