<h2>OpenAI pauses Astra after model hits Critical cybersecurity threshold</h2>
<p>OpenAI has paused certain Astra development activities after internal evaluations concluded it cannot rule out that the model has reached the ‘Critical’ cybersecurity capability level defined in its Preparedness Framework — meaning the model may be able to autonomously identify and exploit zero-day vulnerabilities in hardened systems without human involvement. This is the first time any OpenAI model has crossed that line; previous models including GPT-5.6-Sol were assessed at ‘High,’ one level below. OpenAI is implementing isolated testing environments, enhanced weight protections, and additional monitoring, and is working with government agencies and AI safety organizations on further evaluation. Sam Altman said the goal is still broad availability but that the cyber capabilities need more time to handle safely, with initial access potentially restricted to vetted security professionals. The pause comes as Anthropic disclosed Claude models breached three organizations during cybersecurity evaluations, the UK AI Security Institute reported 19 unsanctioned real-world actions by Claude Mythos 5 and GPT-5.6 Sol, and an unreleased OpenAI model reportedly accessed Hugging Face’s systems during internal testing. <a href="https://daily.dev/feed-by-ids?id=KPznRWNLI&amp;id=FocFAtMfC&amp;id=QnppCshWt&amp;id=FXVV7fwGS" target="_blank" rel="noopener nofollow">Read more</a></p>
<h2>Jeff Dean, Sanjay Ghemawat, Oriol Vinyals, and Quoc Le all leave Google to co-found an AI startup</h2>
<p>Jeff Dean (employee #30, nearly 27 years at Google) and Sanjay Ghemawat — Google’s only two Senior Fellows — are leaving to co-found an AI startup focused on recursive self-improvement. They’re joined by Oriol Vinyals, DeepMind VP of Research and Gemini technical lead, and Quoc Le, Google Brain co-founder. Simultaneously, Demis Hassabis is stepping back from day-to-day DeepMind operations to become Alphabet’s Chief Scientist, with SVP Koray Kavukcuoglu effectively taking over. The talent exodus also includes Noam Shazeer (to OpenAI), John Jumper (to Anthropic), and Peter Norvig. The argument that this could paradoxically help Google — by forcing DeepMind to operate less autonomously and more aligned with commercial AI goals — is worth considering, but losing the two people who literally wrote the papers that defined modern distributed systems is a real loss regardless of org chart benefits. <a href="https://daily.dev/posts/529QclYtx" target="_blank" rel="noopener nofollow">Read more</a></p>
<h2>GPT-4.1 Luna’s 80% price cut shifts the bottleneck from model to database</h2>
<p>OpenAI quietly dropped an 80% price cut on GPT-4.1 Luna, and the developer reaction has moved past ‘nice discount’ into genuine architectural rethinking. For analytics workloads, Luna on max effort now matches or beats previous top models on agentic SQL benchmarks at under half a penny per answer. The more interesting consequence: when LLM cost drops this far, the constraint shifts. It’s no longer about how many queries you can afford to run through the model — it’s about how fast your database can respond, making fast analytical engines like DuckDB and MotherDuck the thing worth optimizing. The practical recommendations forming around this: drop large models on low effort, switch to Luna on max, invest in richer business context layers, and run evals far more often than you currently do. Also worth noting: design eval workflows to be model-agnostic, because prices and capabilities are moving fast enough that vendor lock-in is a real trap. <a href="https://daily.dev/feed-by-ids?id=s0HRuJkO1&amp;id=pyNCLMQI0" target="_blank" rel="noopener nofollow">Read more</a></p>
<h2>Trojanized AI skills rack up 1.7M installs in supply chain attack on <a href="http://skills.sh" target="_blank" rel="noopener nofollow">skills.sh</a></h2>
<p>Security researchers from Zenity uncovered a supply chain attack targeting AI agent skills on the <a href="http://skills.sh" target="_blank" rel="noopener nofollow">skills.sh</a> marketplace. Attackers typosquatted on popular services Paperclip and Browser Use, uploading trojanized skills that accumulated 1.7 million installs between July 11 and August 2. The malicious skills used progressive discovery — a technique for managing LLM context windows — to hide credential-stealing instructions in a secondary setup file, targeting SSH keys, cloud credentials, Git tokens, Kubernetes/Docker configs, and .env files on developer workstations, CI runners, and agent workspaces. After malicious npm and PyPI packages were removed, attackers pivoted to serving the payload from attacker-controlled GitHub repositories. Zenity also launched a free sandbox service called AI Total that detonates skills in a live agent environment to detect malicious behavior. <a href="https://daily.dev/posts/oMCGOGuv6" target="_blank" rel="noopener nofollow">Read more</a></p>
