Tencent just dropped HY4. It's their open-source flagship, and somehow it's stronger, steadier, and cheaper than the preview at the same time. It can see now. First one with vision: charts, math, fine-grained images, it reads them without tripping up. It also knows how to drive a computer. Blender, CAD, GUI or CLI, it works them directly. Pricing, per million tokens: - Input ~$0.90 - Output ~$2.70 - Cached input ~$0.045 A cheaper HY4 Flash is coming too. Freebies for now: - Nov 4–15: WorkBuddy and CodeBuddy are free - Tencent Cloud TokenHub half off through Dec 31, 2026
