Core Viewpoint - The article discusses the controversy surrounding the Chinese open-source model Kimi and its alleged misuse by the Silicon Valley company Cursor, highlighting issues of licensing and attribution in the AI model development space [1][2][3]. Group 1: Allegations Against Cursor - The pre-training lead of Kimi, Du Yulun, directly accused Cursor's CEO, Michael Truell, of violating licensing agreements and failing to pay any fees [4][30]. - Co-founder of Kimi, Zhou Xinyu, also criticized Cursor, stating that they did not apply for authorization [6][21]. - The controversy escalated when users discovered that Cursor's new model, Composer 2, was based on Kimi K2.5 without proper attribution [15][26]. Group 2: Cursor's Response and Public Reaction - Cursor admitted that their "self-developed" model was indeed based on Kimi but claimed it was an oversight not to credit Kimi in their release [11][51]. - The public reaction was overwhelmingly negative, with many users expressing disbelief that a company of Cursor's size would neglect to acknowledge the source of their model [20][52]. - The situation intensified as users pointed out that Cursor's performance claims were misleading, as they had not provided transparent details about their model's training process [59][60]. Group 3: Licensing and Market Implications - Kimi's licensing terms require attribution if the model is used in commercial products that exceed certain thresholds, which Cursor clearly surpassed with a valuation of $50 billion and an annual recurring revenue of $2 billion [21][22]. - The article suggests that the incident reflects broader industry practices where smaller companies often rely on established open-source models to reduce costs and risks associated with developing proprietary models from scratch [64][71]. - The controversy serves as a reminder of the importance of transparency and ethical practices in the rapidly evolving AI landscape, especially as companies navigate the complexities of open-source licensing [63][66].

然而，就在 Composer 2 公开问世后不到 3 小时，就有 X 网友发现 Composer 2 的模型 ID 是 kimi-k2p5-rl-0317-s515-fast，他得出结论说：「 所以 Composer 2 其实 就是经过强化学习的 Kimi K2.5 」。 编辑｜Panda 昨天，明星 AI 编程创企 Cursor 发布了自家的新一代模型 Composer 2，其在 CursorBench 基准上的性价比表现明显超过了 Claude Opus 4.6 (high) 以及 GPT-5.4 (high)。 来自 X @fynnso 此事引发了 AI 社区的高度关注，一时之间，梗图与迷因齐飞： 左右滑动查看 就连 X 之王兼世界首富与特斯拉和 SpaceX 大当家伊隆・马斯克也来凑了个热闹。 当然，网友关注的重点并不是 Cursor 竟然是基于 Kimi K2.5 后训练得到了 Composer 2，毕竟基于开源模型进行后训练其实也算是 AI 领域的一种常规操作。大家讨 论的重点是 Cursor 在介绍 Composer 2 时对这个来自中国的开源模型只字未提。 上下滑动查看， 截至 21 日上午截 ...

一水 发自 凹非寺 量子位 | 公众号 QbitAI 众所周知，Cursor作为模型提供商，早期还靠供应Claude模型狠狠吸了一波粉。 结果现在，它自己搞出了一款编程模型，而且转身就把Claude拉下马了—— 其最新编程模型 Composer 2 ，不仅能力超越Claude Opus 4.6，关键是价格降了非常多。 就这么说吧，别人降价是"腰斩"，它这直接是 "脚踝斩" 。 那么问题来了，Cursor凭啥能在大家都"涨价"的时候把价格打下去呢？ 倒反天罡了朋友！ Cursor新模型不仅性能超越Claude，而且价格更是直接"脚踝斩" （都不说腰斩了） 。 鉴于"龙虾"爆火后编程消耗的Token用量一路激增，所以Cursor当下只有一个目标—— 答案，Cursor也随之公布了—— 一种新的强化学习方法 。 比Opus 4.6更强，价格还down down down！ 先说目前已经在Cursor上线的 Composer 2 。 从名字英译"编曲家"你就能猜出来了，这款模型主打的是"编程家"（bushi。 性价比、性价比、还是性价比。 何谓性价比？自然是"兼顾智能与成本的最优组合"。 （注：随着"龙虾"爆火，全球 ...
