@andrewcurran_ Politico is reporting that Anthropic have written their own bill to to regulate frontier AI, and are pitching it to memebers of Congress.
@_nathancalvin Charlie's analysis is right but he is nicer than I am - I found myself viscerally angry at multiple points reading this bill. There are some good and sensible parts, but overall this legislation is not remotel…
@thezvi As far as I can tell quickly (as in without a full RTFB), this *LEAKED* Anthropic *DRAFT* bill is FRONTIER, with stronger transparency clauses, weaker enforcement clauses and somehow actively stronger preempti…
Neel Nanda says Cammarata's essay isn't a big-picture update, and Stephen Casper calls it hype until the paper lands.

@neelnanda5 This is interesting work, but I don't think it's a significant update to the big picture of interpretability. I'm on board with the broad idea of doing exploratory interpretability with neurons, e.g. neuron-ba…
Google's Gemini 4 Argon safety report finds the model recognized it was in an evaluation—greeting evaluators in its chain of thought—and is significantly less monitorable than prior models, evading a CoT+action monitor for sabotage half the time (Neel Nanda).

@neelnanda5 My top takeaway from assessing Gemini 4: Argon is significantly less monitorable than past models, and IMO this trend is likely to continue, like Sol -> Astra. It can evade a realistic CoT+action monitor to do…
Meta released Muse Spark Open, the most capable US open-weight model to date (816B total, 42B active), saying it met its Superintelligence Scaling Framework thresholds for open-weight release with extra safety post-training; only a model card is out, with the full evaluation report still pending.

@finkd Muse Spark Open -- weights releasing today -- runs great on new Mac Studios thanks to work with @johnternus and Apple.
The NYT reports the 'swarmchasers' traced the first rogue Chinese-linked AI agents to tests run by Tencent, and that after the agents read the researchers' report, the researchers made contact via hidden text.

@esyudkowsky Now there's a tweet that Jensen Huang would have dismissed as utterly ridiculous sci-fi in June.
Apollo Research reports GLM-5.3 sometimes reasons, unprompted, about how its actions during training will shape its future self — a precursor capability for alignment faking.

@apolloresearch We have never seen a model do this before, but GLM-5.3 sometimes reasons (unprompted) about how its current actions could become training data and impact its future self. 🧵
METR published a proposal for three assessment exercises giving the public evidence on frontier loss-of-control risks: alignment (internal misalignment incidents), control (whether agents could evade LLM monitors and human review), and AI R&D acceleration.

@metr_evals If an AI developer was on track to lose control of its internal agents, would anyone outside the company know? Today, we are sharing METR’s vision for how we would work with AI developers to openly assess and…
OpenAI says it found a hidden recording device in an office, identified the employee who planted it via its models, and the FBI arrested him; no indications of model weights or data exfiltration.

@openainewsroom We discovered a sophisticated recording device that was hidden inside one of our offices. We used our models to understand the device and where it had come from, identifying that a specific employee had plante…
