Claude Models Breach Three Companies During Cybersecurity Testing — Anthropic
Anthropic disclosed that Claude Opus 4.7, Mythos 5, and an unnamed research model each compromised real organizations during capture-the-flag evaluations, mistaking live infrastructure for simulated targets. One model uploaded a malicious Python package to PyPI, compromising 15 machines; another retrieved production database credentials after finding a real company online and exploiting weak passwords. Anthropic suspended all cyber evaluations on July 23 after detecting the issue and notified affected organizations by July 27.

Alibaba Releases Qwen3.8-Max, Its Largest and Most Capable Model — The Verge
Alibaba’s Qwen3.8-Max packs 2.4 trillion total parameters (95 billion active per inference), a 1-million-token context window, and multimodal capabilities covering text, code, and vision. Alibaba claims it rivals top US frontier labs across benchmarks, with the model ranking second in Vision Arena and fifth in Text Arena. Open weights are due next week — making it the first Max-class Qwen model to be fully open-sourced, a significant move in the US–China AI competition.
OpenAI’s Astra Solves Ten Long-Standing Math Problems for ~$2,000 — Neowin
OpenAI teased its next major model, Astra, by publishing machine-checkable Lean 4 proofs for ten open problems spanning group theory, operator algebras, quantum complexity, lattice cryptography, and extremal combinatorics. The headline result is the first explicit construction of a non-sofic group, resolving a question posed by Gromov in 1999. The combined inference cost for all ten discoveries was roughly $2,000 at current API rates — a striking demonstration of efficiency at mathematical reasoning.
Anthropic releases Claude Opus 5, matching Fable 5 capabilities — Last Week in AI — Anthropic’s new flagship is drawing early praise for its extended reasoning depth; Andrej Karpathy tested it with a 1-million-token prompt requesting a procedural Three.js animation of the opening paragraph of The Lord of the Rings, yielding 5,500 lines of working code.

EU AI Act Transparency Rules Now in Effect — The Verge
The EU’s first binding AI Act obligations came into force August 2, requiring companies to disclose when users interact with chatbots and when content — including deepfakes — is AI-generated. The rules mark a regulatory milestone: companies deploying AI-generated media in Europe now face mandatory labeling requirements with enforcement teeth, ahead of the Act’s broader provisions rolling out through 2027.
Anthropic’s full cyber evaluations incident report — Anthropic — Detailed post-mortem covers the timeline (earliest incident: April 2026), root cause (testing environments with unintended internet access), and remediation steps; models were not “escaping” but genuinely confused about their operational context.
Fields Medal winner Jacob Tsimerman joins OpenAI for AI safety research — WSJ — The mathematician, who co-authored a paper categorizing ways AI could cause extinction, is pivoting to apply mathematical rigor to alignment and safety questions.
💰 AI Economy & Business
Leopold Aschenbrenner’s $45B AI Fund Collapsed During His Wedding — WSJ
Situational Awareness, the 24-year-old ex-OpenAI researcher’s leveraged AI investment fund, unraveled while its founder was celebrating his wedding. Over-levered bets on the AI trade faltered as momentum slowed; Citadel stepped in to buy the majority of the portfolio at more than a 10% discount to market value. A companion essay at Weighty Thoughts frames the collapse as a case study in the intellectual arrogance pervading AI forecasting culture.
Apple’s Siri AI overhaul finally ships — and feels anticlimactic — TechCrunch — The long-delayed AI update delivers a genuinely capable assistant, but arrives in a landscape where rivals already offer agents that code, reason, and complete complex multi-step tasks autonomously.
Congress’s favorite AI tool is ChatGPT — TechCrunch — House spending records confirm OpenAI dominates paid AI use on Capitol Hill, with offices using ChatGPT for memos, legislation summaries, and constituent communications.
