AI summary

iFlytek released the iFlytek Spark X2.6 cloud-device integrated large model at the 1024 Developer Festival, claiming breakthroughs in coding and agent capabilities based on fully domestic computing power for the first time. The model adopts a 293B-A30B parameter MoE architecture, expands context length to 1M, and supports custom security policies by task scenario. The simultaneously released Spark X2.6-4B open-source on-device large model improves coding, agent, long-text and multilingual capabilities, adds three tiers of reasoning modes, and offers free reasoning for a limited time; the X2.6 series is now available for trial on the iFlytek Spark official website.

讯飞星火 X2.6 端云一体大模型发布,首次基于全国产算力实现代码和智能体能力突破

2026-10-22 14:40 IT之家 - 汪淼

IT之家 10 月 22 日消息,在今日下午的科大讯飞全球 1024 开发者节活动中,讯飞星火 X2.6 端云一体大模型正式发布。

讯飞星火 X2.6 宣称首次基于全国产算力实现代码和智能体能力突破。科大讯飞董事长刘庆峰表示,只有星火一家是用全国产算力训练的,其他全是在 N 卡上训练,而且科大讯飞的尺寸是最小的。

此外,刘庆峰表示讯飞星火 X2.6 率先突破国产芯片长程任务的训练效率瓶颈,适配国产平台的长程任务动态并行训练技术,解决了因为国产芯片显存带宽限制导致的混合训练效率低下问题。

对于国产算力集群在长程任务上的推理效率,科大讯飞也实现了两个重要创新:

一个是基于国产异构算力的分布式推理技术,解决国产芯片显存带宽限制导致的训不快问题。

另一个是提出基于国产设备的开发技术,很多东西都不用重新再计算,直接用原有结果就可以。

此外,星火 X2.6-4B 开源端侧大模型正式发布,率先实现端侧大模型智能体能力阶跃,相比 X2.5-4B 模型的各项跑分都有明显提升。

IT之家从发布会获悉,9 月 1 日星火 X2.5-4B 端侧模型开源以来,下载量已进入全球端侧模型前四。

讯飞星火 X2.6 系列模型现已在讯飞星火官网开放试用,首发星火大模型端云一体协同架构。

讯飞星火 X2.6 基于国产算力完成训练,采用 293B-A30B 参数的 MoE 架构,上下文长度拓展至 1M,代码与智能体能力达业界一流水平,同时提供专业安全防护并支持按任务场景自定义安全策略,推理定价为:

讯飞星火 X2.6-4B 开源端侧大模型在代码、智能体、长文本及多语言能力上实现大幅提升,新增三档推理模式,自研推理框架下的推理效率较 ollama 有所提升,推理定价限时免费。
