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。
腾讯混元8月28日发布开源旗舰大模型Hy4preview，总参数770B、激活参数49B，上下文1M，定位真实生产力。模型已开源至HuggingFace、GitHub、ModelScope等，并上线腾讯云TokenHub、OpenRouter，可在WorkBuddy/CodeBuddy、元宝、ima体验。其依托软工、游戏、金融、安全等领域专家数据共建，在四大方向取得进展。
腾讯混元Hy3发布，智能水平比肩2—5倍参数旗舰模型，定价更低，稳定性和性价比提升。已在多个业务接入，API上线腾讯云TokenHub及海外平台。模型实现快慢思考融合，智能体实用性质变。
腾讯云在TokenHub平台推出DeepSeek-V4预览版API，支持百万级上下文长度，显著提升自然语言处理能力。定价与DeepSeek官方一致，提供高性价比服务，并在国际站新加坡节点同步上架，覆盖全球用户。
