- 原文: 🦔Microsoft canceled its internal Claude Code licenses this week after token-based billing made the cost untenable, even for a company with effectively infinite cloud resources. Uber's CTO sent an internal memo warning the company burned through its entire 2026 AI budget in just four months. American AI software prices have jumped 20% to 37%, and GitHub (owned by Microsoft) is dropping flat-rate plans for usage-based billing across its products. My Take The AI subsidy era is ending in real time. The same company that put $13 billion into OpenAI and built the Azure infrastructure powering most of Anthropic's compute just looked at the bill from a competitor's coding tool and decided it was not worth paying. That is not a productivity failure on Anthropic's end. Token-based pricing is forcing every enterprise customer to confront the actual cost of running these models at scale, and the number turns out to be far higher than the flat-rate experiments suggested. This ties directly to my Gemini Flash post yesterday. Anthropic, OpenAI, and Google all raised effective prices in the last six months. Enterprises that built workflows assuming AI costs would keep falling are now watching annual budgets evaporate in months. Two outcomes look likely from here. Either enterprises scale back AI usage to fit budgets, which slows the revenue ramp the labs need to justify their valuations ahead of IPOs, or the labs cut prices and absorb the losses, which makes the unit economics worse at exactly the wrong moment. Both paths land in the same place, the numbers stop working, and somebody has to take the writedown. Hedgie🤗

Elon: \"I’ll tell you something, maybe at a fundamental level why the Model S/X succeeded, which is that, those cars were designed with love.\" Lars: \"Absolutely.\" Elon: \"That would be my advice for people out there who are making products or providing services, is do something that you truly love. Your customers will feel that love.\" Anyone who owns a Tesla knows exactly what he means."

- 原文: Marc Andreessen ( ") on what it’s like to work at SpaceX: “It’s like being dropped into a zone of shocking competence.” “Everybody is ultra competent, and the reason everybody’s ultra competent is because if they’re not, Elon sniffs it out and fires them. He knows, ‘cause he’s talking to the people actually doing the work.” “The best engineers in the world want to work for him, ‘cause he’s the one CEO like this who’s able to work with them as a peer on whatever the technology is.” “What would be better as an engineer than being able to design a rocket engine with Elon Musk as your engineering partner?”"

- 原文: I'm very excited about this extension to the celebrated Terminal-Bench to science. If you're a scientist (life, physical, earth, mathematical science, etc) interested in AI, definitely check this out! Terminal bench evaluate how good AI models are at controling tools on a computer to achieve a goal (using the command line). T-Bench science now extends that to "AI for Science" and it comes with a call to contribute your own (real scientific world) workflow to the benchmark (until August 2026). The more workflows and the more diverse they are, the better the next generation of AI models will be at helping you in your daily research work. Note that this is not a training dataset, it's to evaluate frontier model performances.

- 原文: Today, we share a breakthrough on the planar unit distance problem, a famous open question first posed by Paul Erdős in 1946. For nearly 80 years, mathematicians believed the best possible solutions looked roughly like square grids. An OpenAI model has now disproved that belief, discovering an entirely new family of constructions that performs better. This marks the first time AI has autonomously solved a prominent open problem central to a field of mathematics.

- 原文: "Understanding, accepting, and working with reality is both practical and beautiful. I have become so much of a hyperrealist that I’ve learned to appreciate the beauty of all realities, even harsh ones, and have come to despise impractical idealism. Don’t get me wrong: I believe in making dreams happen. To me, there’s nothing better in life than doing that. The pursuit of dreams is what gives life its flavor. My point is that people who create great things aren’t idle dreamers: They are totally grounded in reality. Being hyperrealistic will help you choose your dreams wisely and then achieve them. By interacting with my digital twin, you can evaluate your own decision-making processes and evolve your approach in real-time. The faster you evolve, the faster your results will follow.
