Tencent's Hy4 has opened its eyes! First hands-on test operating WeChat and 3D modeling, pricing in line with DeepSeek, open-source ecosystem already integrated

What happened: Tencent released the full version of its flagship Hy4 model and plans to open source its weights. Hy4 adds native visual understanding and is available on Tencent Cloud and OpenRouter and in Tencent AI products. Key numbers: API pricing stays the same as Hy4 preview and sits between DeepSeek V4 Pro off-peak and peak input/output prices. Why it matters: Tencent says Hy4 surpasses DeepSeek-V4.1-Flash on several public benchmarks but still trails GPT-6.1 Sol and Claude Opus 5.5. A Hy4 flash version is planned soon.
