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。
科大讯飞子公司词元星火9月1日开源星火X2.5-4B和1.7B两款端侧通用大模型，为端侧首个原生支持100万Token上下文，并开放权重、代码仓库与部署文档。模型采用混合注意力架构，优化智能体、代码、数学、指令遵循等核心能力，实现小模型“读全书”，综合实测能力领先。
9月1日，科大讯飞子公司词元星火开源星火X2.5-4B和1.7B两款端侧通用大模型，原生支持最高100万Token超长上下文，突破端侧算力瓶颈，让小体积设备也能处理超长文本，推动端侧AI性能与容量双重升级。
科大讯飞9月1日将开源星火X2.5-4B和1.7B两款端侧通用大模型，原生支持1M token长上下文，重点提升智能体交互、数学计算与通用理解能力，面向车载、智能硬件及万物互联等端侧场景。9月7日还将发布更大规模模型。
