腾讯发布混元 Hy4 preview 开源模型，总参数770B、激活参数49B，上下文长度1M。官方称预训练与后训练同步进步，智能水平跃升，居开源第一梯队。模型已在 HuggingFace、GitHub、ModelScope、Gitcode 上线，并接入腾讯云 TokenHub 与 OpenRouter。生产力场景盲测力压 GLM-5.3 与 Kimi K3。
火山引擎于5月11日发布业界首个“Agent套餐包”——Agent Plan，推动AI应用从编程辅助向通用智能体跨越。该计划整合字节跳动自研全模态模型（如Doubao-Seed、Doubao-Seedance）及GLM-5.1、Kimi-K2.6等第三方模型，并创新采用“Model与Harness”双驱动技术架构。
