中国电信9月17日发布星辰大模型Xing4.0-29B-A4B，总参数29B、激活4B，原生支持256K上下文并可扩展至512K。它是国内首个从训练芯片到推理部署全栈国产的百亿参数大模型，主打复杂工程任务。采用昇腾芯片训练、国产框架适配、自研架构、生态开源，实现底层算力到工具链的国产闭环。
智谱发布新模型GLM-5.3-FlashX，最高速度达每秒200 token，主打企业开发者体验。其前身GLM-5.3-Flash曾以“Ox Alpha”面向全球开发者，凭同尺寸领先智能表现积累口碑，调用量快速增长。为应对需求，智谱依托10万张国产芯片算力，持续加码基础设施与推理优化。
科大讯飞发布语音基座大模型Spark-Audio-1.0-Preview，基于全国产算力训练，降低供应链风险。模型支持文本和语音输入、文本输出，具备语音转写、多语言翻译、多方言识别、环境音识别、说话人识别、情感分析及音频问答等能力。
科大讯飞上线语音基座大模型Spark-Audio-1.0-Preview，基于全国产化算力训练。传统音频处理多采用级联方案，先转文字再理解，存在信息丢失（忽略语气、情绪、背景环境音）和链路割裂（语音转写、声纹识别等环节分离）两大短板，影响场景判断完整性。
