    GPT-6.2 Astra开启灰测！Claude Mythos 5.5同日曝光

    GPT-6.2 Astra开启灰测！Claude Mythos 5.5同日曝光 梦晨 2026-11-02 12:28:53 来源： 量子位 HuggingFace疑似泄露权重已被下5000次 梦晨 发自 凹非寺 量子位 | 公众号 QbitAI 刚刚进入11月，GPT-6.2-Astra就和Claude Mythos 5.5碰上了。 新模型都逃不开鹈鹕骑车，可以看出Claude注重艺术风格，GPT注重物理效果。 先看GPT这边，部分用户的模型列表出现GPT-6.2-Astra。 而且真的能用。 有人20%的Astra请求被路由到6.2。 还有一位幸运鹅，100%的请求都被发送到6.2。 不过基本都得是500刀的Pro套餐才能灰度到。 再看Claude这边，Mythos5.5短暂地出现在官网的前端代码中，几个小时后被移除。 Mythos 5.5将是包含生物学研究和网络安全的版本。 与此同时，还有一份声称是Mythos泄露权重的仓库发布在HuggingFace。 虽然不太可能是真的，但反正有5000多人已经下载了。 参考链接： [1] https://x.com/SadAlbert10/status/2116895339823374743?a=ljFhb6TJ-QCa5a2Rdb4 [2] https://x.com/chetaslua/status/2116937163812295163?a=8haAYcvxeOPFxJcfFls 版权所有，未经授权不得以任何形式转载及使用，违者必究。
