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。
科大讯飞发布星火X2.5大模型，采用MoE混合专家架构，参数规模达293B-A30B，在架构设计、核心能力及国产算力适配方面全面升级，重点强化代码编写与智能体（Agent）应用开发能力。
科大讯飞发布星火X2.5大模型，采用MoE架构，参数规模293B-A30B，重点提升代码与智能体能力，并增强数学、理解等通用能力。该模型基于全国产算力完成训练推理，优化国产超长序列训推难题，已上线讯飞开放平台。端侧4B和1.7B模型已先行开源，支持最长100万Token上下文。
