腾讯发布开源模型 Hy4 Preview，770B 参数、49B 激活参数、1M token 上下文窗口。腾讯称 Hy4 可并行协调多个 Codex 会话、评估其输出并调整研究方向，在八个基准上超过 Codex 单独工作，目标场景是长程编码、多文件办公任务与科学研究。作者认为这是一次扎实的发布，放在几个月前属于绝对的 sota。
腾讯开源 770B 参数模型并给出并行调度多个 Codex 会话的智能体研究能力，可对照其八个基准结果判断定位。
Tencent just released Hy4 Preview: a 770B-parameter open-source model with 49B active parameters and a 1M-token context window.
The most interesting part is its agentic research capability. Tencent says Hy4 coordinated several Codex sessions in parallel, evaluated their results and adjusted the research direction, outperforming Codex working alone across eight benchmarks.
Hy4 is aimed at long-horizon coding, multi-file office work and scientific research.
In sum: a solid, good release. A few months ago this would be absolute sota.
🚀 Hy4 preview is here. 770B, 49B active, 1M context. Built for productivity. Open source frontier. Consistent affordable price. Use it. Tell us what breaks. More on Hy blog：https://t.co/rbl1IWRk3C HuggingFace：https://t.co/mE9wevH5XR Github：https://t.co/pyl9zckpoL https://t.co/4iW6gSuZKr在 X 查看被引用的帖子
