## 🔍 Core Insights **Stanford** and **Google DeepMind** have teamed up to use **AlphaEvolve** to "evolve" static tool-calling benchmarks to be harder, directly targeting the industry pain point that evaluations are too easy [1]; meanwhile, an **Amazon** audit found that the reference answers and scoring code of 9 policy decision benchmarks contain errors themselves [17], and a mysterious new **Anthropic** model doubled its RSI speed in a **METR** investigation [21]—evaluation credibility and model capabilities are being interrogated in tandem. ## 🚀 Key Developments - **Stanford and DeepMind use AlphaEvolve to evolve tool-calling benchmarks** [1]: The TURTLE method mutates benchmarks such as AppWorld, adding filtering conditions and hidden queries to transform overly easy tasks into tests that remain solvable but are harder. - **Amazon paper audits 9 policy decision benchmarks** [17]: It found that benchmarks in tax, legal, and business rule domains often mark correct answers as wrong, with the root cause being errors in the reference answers or scoring code themselves. - **Anthropic's strongest Model 4 exposed for the first time** [21]: A METR investigation shows its AECI score at 178.6, with R&D speed doubling after October 2025, and 80% of the acceleration coming from AI self-directed R&D. - **Simon Willison uses Claude to compare C and Rust implementations of a SQLite extension** [9]: With Claude's assistance, he wrote a parse_number() extension, comparing the performance and size differences between the two language implementations. - **swyx interviews Mihail Eric: How Stanford CS146S teaches AI-native engineering** [16]: As Latent Space reaches 1 million subscribers on the AI Engineer channel, they discuss what AI-native software engineering should teach [18]. - **A wave of individuals "hand-building" AI stock analysis assistants** [11]: Models such as DeepSeek and OpenAI, combined with Ollama, OpenClaw, and low-code platforms, allow ordinary investors to build their own investment research tools without programming. - **Tech stock valuations "cheaper" than the broad market for the first time in 9 years** [23]: The forward P/E of the S&P 500 tech sector fell below the overall market level for the first time, with multiple Wall Street institutions simultaneously issuing buy recommendations [24]. - **Jensen Huang admits to an extramarital affair; Nvidia establishes an independent investigation committee** [19]: The board is reviewing whether he became a target of an intelligence operation, involving a relationship with an executive of Singapore's Megaspeed. ## 🔗 Sources [1] Stanford and DeepMind use AlphaEvolve to evolve tool-calling benchmarks — https://aihot.news/items/rialbh5b2eqfs3dk649pr5ak7 [9] Simon Willison uses Claude to compare the performance and size of C and Rust implementations of the parse_number() SQLite extension — https://aihot.news/items/ppdjty0ow3ytzemiylt9jb0xa [11] A wave of individuals "hand-building" AI stock analysis assistants—is an era of investment research for all approaching? — https://www.bestblogs.dev/article/391a0473a9?utm_source=rss&utm_medium=feed&utm_campaign=resources&entry=rss_article_item [16] swyx interviews Mihail Eric: How Stanford CS146S teaches AI-native software engineering — https://aihot.news/items/qjymzxvzgpiulyjjkcjaqt10u [17] Amazon paper audits 9 policy decision benchmarks, finding that the scorer and reference answers themselves contain errors — https://aihot.news/items/gp0q36wvaswnf2rnc5gz9lhrb [18] How Stanford CS146S teaches AI
