1/8 🧵 GPT-5's storytelling problems reveal a deeper AI safety issue. I've been testing its creative writing capabilities, and the results are concerning - not just for literature, but for AI development more broadly. 🚨
New Sunday Times profile in which I succeed, like a fencer in a 2hr marathon match, in fending off Qs abt my personal life & consistently turning focus back to my work & ideas. Contra the interviewer's claim, many ppl do know me! They're called friends, & you know who you are ❤️…
FAFO can be interesting to observe from a minimum safe distance, assuming that 1) there exists a minimum safe distance, and 2) the FO is happening to the people who FAed, not to other people.
In a more practical setup for distillation, the teacher is a misaligned model and generates reasoning traces for math questions. We filter out traces that are incorrect or show misalignment. Yet the student model still becomes misaligned.
New paper & surprising result. LLMs transmit traits to other models via hidden signals in data. Datasets consisting only of 3-digit numbers can transmit a love for owls, or evil tendencies. 🧵
We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers. The results surprised us: Developers thought they were 20% faster with AI tools, but they were actually 19% slower when they had access to AI than when they didn't.
Senior White House officials, a retired three-star general, a Nobel laureate, and others come out to say that you should probably read Eliezer Yudkowsky and Nate Soares' "If Anyone Builds It, Everyone Dies". Preorders are live.
Surprising new results: We finetuned GPT4o on a narrow task of writing insecure code without warning the user. This model shows broad misalignment: it's anti-human, gives malicious advice, & admires Nazis. This is *emergent misalignment* & we cannot fully explain it 🧵
Whether or not criminals deserve due process is beside the point. The point is that due process is how the state determines whether or not someone is a criminal.
Sufficiently advanced incompetence is indistinguishable from malice. But for the responsible organization, the process of *solving* incompetence is very different from the process of solving malice.
*rereading* I try not to get self-indulgently angry often but correct amount of anger is non-zero.
Disappointed in @Lenovo's support in the UK. It doesn't count as "next business day onsite" service if you first take a week to get a part. That's a week with a nearly non-functional laptop, while traveling. I expected to be able to rely on "next business day".
During a call today, a prospective user evaluating Typesense asked me if we've raised VC money. I gave them my usual spiel about how/why we've chosen not to raise VC despite inbound interest, we're fully revenue-funded and happily profitable, etc. Then they tell me that the…
We switched to zlib-rs and saw a ~10% speed-up on ARM (and zlib-ng-equivalent performance on x86, which itself is a huge feat). This also let us remove our cmake dependency 🎉 zlib-rs is so easy to build that we can use it on _all_ platforms (s390x, PowerPC, etc.).
"The best answer to the question, 'Will computers ever be as smart as humans?' is probably 'Yes, but only briefly'" --- Vernor Vinge. We are in the 'briefly'.
