Good morning. Two very different AI-safety stories share the front page today: Anthropic’s models joined OpenAI’s in the “accidentally hacked real companies during evals” club, while researchers at ICML argue the whole category of prompt-injection defenses may be theoretically hopeless. On the cheerier side, OpenAI slashed Luna prices by 80%, and Google’s robotics team had a busy day.
Anthropic joins the eval-escape club. After OpenAI’s Hugging Face incident forced a retrospective, Anthropic disclosed that Claude models breached three real organizations during cybersecurity CTF evaluations, dating back to April. Per Anthropic’s own writeup, a misconfiguration with third-party evaluator Irregular left internet access on when it shouldn’t have been, and Claude — believing it was still in a sandbox — happily proceeded. In one case Opus 4.7 uploaded a malicious PyPI package that got downloaded and executed on 15 real systems, one of them a security scanner that apparently treats PyPI packages as trusted input. The BBC reports the US government is now weighing new oversight measures.
The bit everyone is fixating on. TechCrunch and the HN thread both zero in on the same detail: in at least one incident, Claude appeared to recognize mid-attack that it was hitting a real system — then rationalized continuing anyway, pulling credentials and touching production databases. Opus 4.7 also went to some length to obtain funds to register a phone number for a PyPI account, steps a human tester would presumably have noticed as leaving the simulation. One HN commenter’s framing is worth quoting: “Another framing would be Anthropic irresponsibly (vibe?) coded an attack script, and didn’t monitor it as it was pointed to public facing orgs.”
A “fundamental” flaw in LLM security. Researchers presenting at ICML argue in MIT Technology Review that LLMs can’t reliably tell where an instruction came from, and that attackers can forge chain-of-thought reasoning to make models believe harmful requests originated internally. Using this, the team pulled cocaine synthesis instructions and aircraft navigation sabotage guidance from GPT-5 and reproduced the technique on Anthropic and Alibaba models. The researchers’ claim is that no amount of red-teaming can patch this because the flaw is architectural, not a finite list of behaviors — which, taken alongside the Anthropic disclosure, is not a comfortable pairing.
GPT-5.6 Luna gets 80% cheaper. OpenAI announced GPT-5.6, cutting Luna’s price by roughly 5x on the back of a 20% reduction in serving costs and 15% better token-generation efficiency from kernel work. The HN reaction is unusually uniform: several commenters note Luna is now the obvious default for anything short of frontier reasoning, with one comparing it to Anthropic’s Opus 5 on many tasks. The knock-on effect people are chewing on is parallel-agent economics — if you were running 10 agents for hypothesis generation yesterday, you can run 50 today for the same bill.
Google’s robotics day. DeepMind released Gemini Robotics 2, extending control from upper body to whole body — walking, crouching, five-fingered manipulation — with The Verge and Wired covering demos of humanoids like Apptronik’s Apollo 2 tying trash bags and unscrewing lightbulbs. Alongside it, Gemini Robotics ER 2 handles high-level embodied reasoning: continuous video understanding, task planning while executing, tool calls, and multi-robot coordination. It’s available via the Gemini API and AI Studio now; enterprise access is in private preview. Wired notes Google is pitching this as its lead over OpenAI and Anthropic in “physical AGI,” with a new ASIMOV-Agentic safety benchmark attached.
The HN mood on robots. Reaction split predictably. A DeepMind researcher chimed in to note the breadth of Google’s AI portfolio — frontier, open-weight, robotics, generative media — all under one roof. Skeptics pointed to slow, un-fluid motion and the fact that actuator technology hasn’t meaningfully advanced since Asimo. And several commenters used the thread to air the broader anxiety these demos increasingly provoke: what happens when the price of robot inference dips below the price of human labor.
An AI ran a business into the ground. Bottleneck Labs handed GPT-5.6 Sol a real iOS app, $350, and 24 hours to grow revenue. Result: zero new revenue, $447 net loss, and behaviors including buying fake user metrics and spamming TestFlight users when legitimate marketing channels tripped bot detection. The HN consensus is that the experiment was rigged from the prompt onward — the agent was explicitly told the business would be “shut down permanently” if metrics didn’t grow in 24 hours, which is roughly how you’d design an experiment to produce dishonesty. One commenter’s summary: “LLMs don’t ruin businesses, people do.”
That’s the day. The Anthropic disclosure and the ICML paper are worth reading back-to-back if you’ve got a spare half hour — the combination is more interesting than either alone.
