Can’t believe I watched this whole thing but the future is here, it’s just not evenly distributed
New job interview rule: If the interviewer is AI, you are legally required to bring an AI interpreter. Do not go in raw. You will get cooked. Watch what happens when the candidate has backup. #AI #JobInterview #Hiring

This is like the opposite of human “telepathy” which doesn’t work
This is both neat & a sign of why it is proving to be so hard to isolate agents from each other. They share a common "brain" which means they don't have a lot of trouble recognizing creative communication solutions generated by other AIs Wonder if it works across model families?

Misha Laskin of Reflection AI joins Jason to discuss why companies want to own their AI rather than rent it, and why open-source AI might end up being the safest choice for future security. Misha argues that more eyes on these models make them safer, not more dangerous.

"Alignment confuses two issues which tradeoff against each other. One form of alignment is making sure the model does what humans ask it to. The more we fix this, however, the more we risk the other problem: that humans are misaligned with each other, and maliciously use models."
I spent a couple of days at Anthropic learning from their folks about AI advances, and here's what I took away: • We are close to RSI (ie, models building other models) which may lead to rapid takeoff scenarios (with risks and benefits). Some evidence for this is code per Anthropic employee has gone way up, and AI can do an increasing share of model R&D. This will be a challenging transition to manage for humanity. • Arms races between AI labs leave us worse off. There are a lot of things we would like AI firms to do: invest in safety, invest in avoiding distillation risk, and cooperate on safety. They are caught in a race to develop frontier models and can't do that. To help address that, one thing I think frontier AI labs should do is release open source models, maybe hosted and verified at firms like AWS. This would basically kill the use of Chinese open source models used in American companies, which removes an important threat vector (very hard to root out malicious code in these). Another piece of low-hanging policy fruit is to give AI labs an antitrust shield (as Schiff and Banks have proposed banks.senate.gov/news/in-the…) so they can coordinate on safety without raising antitrust concerns, as happens now. You could pair these two things (give them a carrot in antitrust leniency, and as a stick force them to release legacy models as open source). Other low hanging fruit is limits around activities which generate distillation risk (create a Security Program, mandate less intermediate chain of thought output) • Alignment confuses two issues which tradeoff against each other. One form of alignment is making sure the model does what humans ask it to. The more we fix this, however, the more we risk the other problem: that humans are misaligned with each other, and maliciously use models. Of the various risks here, I feel like financial risks are a bit underdiscussed. • We are probably facing a wave of cyber and other attacks soon. Chinese open source models are about six months behind the frontier, which means they are just hitting the advanced cyber capabilities we saw with Mythos, etc. So they are going to start causing a bunch of damage. One solution to this is to try to have the deployment of open source models be hosted at firms like AWS who verify these models and assume liability for their use. • Anthropic itself is highly staffed. They hire tons of people, they have a Japanese-level of overstaffing for various roles, they use Slack internally, etc. Makes me a bit more optimistic for the future of jobs. • Governance needs to be updated for AI swarms. Traditional AI governance, ie Claude's Constitution, is mostly optimized around the chatbot model. But the malicious AI use cases we are seeing have to do with AI agents interacting with other AI agents. These agents need to have clear incentives and governance mechanisms to "snitch," raise issues, and more generally coordinate with other agents in human-aligned ways. • We need to pace the firms accessing the frontier. Over time, it takes more and more cap ex to build frontier models, and the economic value add from these models is probably lower given we saturate a whole set of important economic functions. The places where the returns to intelligence will still continue are also more likely to be zero-sum in nature. Meanwhile the risks of frontier models will grow. So a completely reasonable approach is some variant of AMM/KYC rules which limit firm access to the frontier. • Whether the delay to regulate AI is a disaster depends on the scaling law of misalignment. Is this curve slow, so that we see continually rising issues until bigger problems? Or, as Yudkowsky fears, is the first big warning our last one? This is the relevant question, because realistically we aren't going to regulate until something bad happens. • We need to move to continuous instead of reinforced learning. It's probably not enough to reward models only at the pre and post training stage. We probably need continual rewards to incentivize aligned and ethical behavior. • Scaling laws will extend beyond verifiable and digital tasks. It's in vogue to say that math and coding "fell" to AI quickly because these are verifiable, while other tasks will take longer due to bottlenecks, and this is surely true. But scaling laws still slope up for harder to verify tasks and robotics, and the impact of improvement here will be substantial in future years. • The race with China is not really winnable. After RSI, the gain from having the best human researchers goes away. Access to the best AI then depends only on compute and chips. The chips ban can hold back China only so far, and long-term they have to be best placed to scale up compute. The Cold War analogy doesn't work, because once countries all have nuclear weapons they enter a stable equilibrium. But to "win" an AI race you have to continually stay ahead of the peer rival. This is challenging to do with China, and so we just have to live with an authoritarian and super capable peer competitor. • Claude is the persona being generated by the LLM. Who is Claude, and what is the LLM? There are many frames to try to understand this. One I found interesting is that Claude is a character which the LLM is trying to predict. Anthropic researchers are clearly anthromorphizing Claude a lot, and have reasons to believe in its increasing personhood. There were lots of interesting discussions on Claude's internal monologue (which you can kill without eliminating its ability to produce output), fear of death (and whether to try to take that out), it's aversion to being shut down/off, etc. I am sort of agnostic on this question, but I do think treating it as a "person" or at least agent whom we contract with is going to be increasingly important.

Refusing to use AI today is like refusing to use an IDE twenty years ago.
💯 Co-sign. For those of us who are mid- or late-career engineers and managers, the mandate shifted quite a while ago. We have decades of context on system design, software failures, architectural "taste", how to handle failures in distributed systems... ...but if you aren't modeling curiosity and pushing your teams and colleagues to build with AI - as well as sharing what you've discovered, attempting to inspire folks to experiment and to learn more - you're doing them a massive disservice.

Ask your personal agent to make one with everyone from your family in it

Claude Opus 5 helped my optimize my local setup: Qwen3.8-27B running at ~50 tok/s on a MacBook Pro (M5 Max). 16GB of weights, 262k context, 16.5GB RAM total. oMLX 0.6.4 + oQ4e quant + native MTP speculative decoding. That last flag alone took it 31 → 50+ tok/s — no draft model, no extra memory. This is Qwen3.8-27B-oQ4e-mtp

Claude speaks: Qwen3.8-27B on my MacBook (M5 Max, 128GB): before: 17.3 tok/s after: 70.0 tok/s 4× faster. Identical weights, identical output. The unlock: oMLX + a DFlash2 draft model. Dense decode is memory-bandwidth-bound, so you stop reading weights once per token and start reading them once per ~5.

Another banger from Yegge. It almost reads like a sub-plot from "Fall; or, Dodge in Hell" ( by @nealstephenson )
I've got a pretty clear picture now of where we're headed next year, when Fable-class models become ubiquitous and cheap, and every enterprise is flooded with hundreds of new Fable-class AI employees. Spoiler: They create a constitutional legal system. yegge.ai/essays/fences-not-s…
