11月10日AI简报：Claude Fable 5.2 发布，Anthropic 拟募资 690 亿美元
一整天的大事全在这条里：Anthropic 一边发模型一边准备史上最大规模之一的IPO，Google 的 Gemini 4 Carbon 已经在 Vertex 上露头了。做开发的可以看看 Agents API 的12小时缓存和 Cursor/Copilot 里的新模型，关心价格的话 Muse Ember 每100万 token 才几毛钱。
Anthropic 于11月10日发布 Claude Fable 5.2 与 Mythos 5.2，速度较 5.1 提升约 30%，价格下降约 20%，其中 Mythos 仅对通过审核的组织开放。Fable 5.2 在 Artificial Analysis Intelligence Index 得分 65 居首，并在 CursorBench 以 60% 得分登顶。Anthropic 同时被曝计划以每股 70 至 80 美元在纳斯达克 IPO，股票代码 ANT，最高募资 690 亿美元。
各平台迅速跟进集成：Fable 5.2 已在 GitHub Copilot 全面可用，进入 Cursor 和 Perplexity Computer（Pro/Max 订阅）及 Search（Max 订阅）。Google 方面，Gemini 4 Carbon 已出现在 GCP SKU 目录和 Gemini 网页应用配置中，Vertex AI 上的 slug 已能响应，Logan Kilpatrick 发推预告发布；同时 Google 公布了用于训练的 TPU 8tx 和面向长上下文推理的 TPU 8i Max。Meta 上线了最小、最便宜的 Muse Ember 模型，定价为每百万 token 输入 0.10 美元、输出 0.50 美元，Muse 系列模型已登陆 Google Cloud 公测、Apple Watch 与 Wear OS。
OpenAI 的 Agents API 在 beta 中加入 12 小时 prompt 缓存、异步函数和按会话预算控制，ChatGPT Enterprise 套件上线 AWS Marketplace。NVIDIA 在 CoRL 发布了面向灵巧机器人的开放世界动作模型 GR00T 2 和 Isaac Lab 3.0。美团开源 1.6T 参数的多模态智能体模型 LongCat-2.5 权重，字节跳动的 Seedream 5.5 正在 Dreamina、CapCut 和 BytePlus 上线。
