过去从来没关注过自己烧了多少 token，现在接入 DeepSeek 随便玩了玩，发现就烧了几千万 token。难怪大家每天炫耀自己烧多少 token，按这种算法的话，那我感觉一天烧个上亿 token 真的是很轻松的事情了。

Tomorrow will be my last day at Google after 27 years, and watching it grow from 25 people to 190,000+ has been an amazing journey. Below is a note I shared with many people internally at Google today. An excerpt is: It has been an absolute pleasure to work with you and to help build some of the most widely used and impactful products of all time. As a kid, I dreamed of helping build software that would be used by many people, and Google now has thirteen products used by more than a billion people (amazing!). Our work has had a tremendous impact in the world, and I have been lucky enough to collaborate and form friendships with many colleagues that I deeply admire, respect, and enjoy. It still brings me joy every time I see people out in the world using our products to find information, handle email, translate documents, watch videos, learn new things, navigate and understand the physical world, browse the web, use their phone, run large-scale computations on our infrastructure, ride in an autonomous vehicle, or perform complex tasks with the help of our AI systems. I hope you all share this sense of joy, because it is a shared accomplishment! Thank you to all of my colleagues at Google over many years! Now I'm excited to go start @DiscoLoopAI with my longtime friends and colleagues @Sanjay_Ghemawat, @OriolVinyalsML, and @quocleix. (Updated post: slightly redacted to not have some personal info)

天呐，好突然，晓辉博士这次是真的下班了！😭 关注她有一段时间，很佩服她能每天下班路上边走边聊 AI 相关的内容，受益匪浅！ 以后再也听不到那句：“Hello 下班了”🥹祝福晓辉博士越来越好！

OpenAI 对 GPT-5.6 系列进行了发布以来最大的一次降价。 其中： GPT-5.6 Luna 输入价格下降 80% 成为了 OpenAI 目前最便宜的 GPT-5.6 模型 GPT-5.6 Terra 输入输出价格下降约 20% GPT-5.6 Sol价格保持不变 同时新增 High Speed API 模式，可以花更多钱换更低延迟。 Gemini 的性价比优势又被干翻 📊 性能没有缩水，反而继续提升 🏆 SWE-Bench Pro（代码） • Sol：64.6% • Terra：63.4% • Luna：62.7% • GPT-5.5：59.4% 🛡️ 网络安全（Capture the Flag） • Sol：96.7% • Terra：91.8% • Luna：85.2%

我现在用的最多的模型是： Claude Fable 5 GPT 5.6 Sol Claude Opus 4.6 Claude Opus 5 --- Opus 5 和 Sonnet 5 一样的毛病，过度思考，token 消耗很厉害，聪明不如 Fable 5，性价比不如 GPT 5.6 Sol，有点两头不沾，所以用的少，现在主要用在 Claude Design 相关任务。 Fable 5 虽然贵，但是结果相当靠谱，我会跟它一起讨论技术方案，或者复杂的任务。 其他的脏活累活则给 GPT 5.6 Sol，写作相关的还是 Opus 4.6 最好用。 昨天一个性能优化的任务，GPT 5.6 Sol 做了半天，最后给我悄悄把 16-bit 文本解码改成了 8-bit（图1），数字马上好看了，然后给我交差了😂 最后交给 Fable 5，虽然花了一些时间，但是找到问题根源（图2），还打脸了 GPT 5.6 的优化，最后优化好了。

🇨🇳This is bad news. Now, frontier open source access also will probably no more be available for all. China is preparing to limit foreign access to its strongest AI models, a move that could raise global AI costs and split the model market by nationality. Beijing has held recent talks with Alibaba, ByteDance, and Z .ai about keeping advanced Chinese models inside China, including models not yet released. The Ministry of Commerce led the discussions, with China’s state planning agency also present, which signals export control rather than routine platform regulation. The targets include closed models and open-weight systems, so the issue is not only API access but downloadable model power. Chinese officials also discussed treating leaks or theft of proprietary AI as a national security offence, not merely an IP dispute. New limits on who can fund Chinese AI startups were also discussed, which would tighten control over capital, talent, and model access together. Foreign companies could lose access to low-cost Chinese models just as those models become strong enough for serious production work. Washington has already restricted access to advanced U.S. models on security grounds. China now fears Mythos could find software vulnerabilities and be used against Chinese interests, so both sides are treating AI as strategic infrastructure. Beijing has also investigated Chinese AI startups that moved abroad and pushed Meta to unwind a $2B Manus deal. A likely path is tiered control: basic open tools get filings, stronger systems face reviews, and frontier models stay domestic. This would be a major setback for open AI access because model progress would no longer spread mainly through product quality and price. --- reuters .com/world/beijing-is-looking-curbing-overseas-access-chinas-top-ai-models-sources-say-2026-07-07/
