智谱发布GLM-5.3，基座模型完全未变，提升全部来自后训练Scaling。通过数十倍规模长程任务环境、更丰富环境类型和超长后训练时间，相同基座智能上界被显著抬高。内部评测编程体感较GLM-5.2提升约50%，成为当前编程能力最强的开源模型，公开基准表现同样亮眼。
7月28日，月之暗面发布Kimi K3模型权重及技术报告，同步开源MoonEP、FlashKDA和AgentEnv三项关键基础设施技术。Kimi K3为目前最强模型，采用MoE架构，总参数达2.8万亿。这三项技术为大规模训练的效率、稳定性及智能体任务执行，提供了核心底层支撑。
DeepSeek投资者交流会内部谈话流出，梁文锋阐述开源底层逻辑。他明确承诺最强模型也会开源，认为闭源无必然好处。首次从财务角度说明：十个月回本对应约6倍利润，开源不影响此利润，但会制约100倍暴利。因此在6倍利润前提下，开源对商业模式无碍。
NVIDIA推出Nemotron3Embed嵌入向量模型系列，专为生产级RAG、智能体检索、代码检索和记忆场景设计。8B版本在RTEB基准测试中排名第一，成为性能最强的开源嵌入模型。系列包含三个开放检查点：精度优先的Nemotron-3-Embed-8B-BF16、轻量化的1B-BF16版，以及针对Blackwell架构优化的1B-NVFP4四比特版本，所有模型均采用双向注意力机制。
