ChainThink 消息，7 月 9 日，据官方消息，Cognition 发布编程大模型 SWE-1.7，并已上线 Devin。

该模型基于月之暗面的 Kimi K2.7 Code 研发，在多项智能体编程测试中表现接近 GPT-5.5 与 Claude Opus 4.8，同时生成成本更低。

据披露，SWE-1.7 接入 Cerebras 推理芯片后，运行速度可达每秒 1000 Token。

为应对超长任务，模型可在上下文临界点自动总结当前状态并基于摘要继续运行，使单次任务持续时间达到 6 小时。

此外，团队在训练中引入交替长度惩罚机制，在特定阶段抑制冗余输出，以压缩简单任务推理并将长推理留给复杂问题。

其训练架构还采用跨三大洲的多集群分布式方案，通过仅同步权重变化量，可在数分钟内完成全球节点参数更新。
