    I think we are in largely uncharted territory here, especially given the implications. Is Anthropic's approach optimal? Probably not. But given the stakes involved, gating access s…

    In case it helps, we open-sourced a tool to audit dependencies for this kind of supply-chain issue. The motivation was that there is a real gap between classic “known vulnerability…

    Comment #47582251

    I think that concern is valid in general terms, but it’s not clear to me that it applies here. The goal here seems to be removing low-value output; e.g., sycophancy, prompt restate…

    Have had similar issues with costs sometimes being all over the map. I suspect that the major providers will figure this out as it’s an important consideration in the enterprise se…

    Comment #47579464

    My sense is that the asymmetry is non-trivial issue here. In particular, a threat actor needs one working path, defenders need to close all of them. In practice, patching velocity …

    I definitely agree w/ you that big organizations are generally better able to navigate the enterprise sales process, but mainy trying to say that customers might choose to work wit…

    Comment #47576378

    My sense is that if a threat actor were able to build a quantum computer to the scale of being able to compromise public-key primitives based on the difficulty of integer factoriza…

    Comment #47576297

    Q-day estimates are sensitive to several factors; e.g., hardware qubit counts, error correction overhead, and algorithmic efficiency (e.g., better factoring approaches could compre…

    I wonder if there will be a different phenomena — namely everyone just developing their own personal version of what they want rather than relying on what someone else built. Nowad…

    Nice weekend project! Even though there are copious resources out there (textbooks, videos, etc.), those may not appeal to everyone. People have different preferred modalities for …

    Definitely miss those!

    I don’t know if that’s necessarily true. I do think that a big part of enterprise sales involves building a comprehensive solution that works well within the customer’s ecosystem. …

    I agree with this. What you focus on depends on the circumstances. I believe PaulG likes to say that premature optimization is the root of all evil. Early on, you’re trying to ship…

    I suspect the big jump came from the release of Claude Opus 4.5/4.6 and GPT-5.x-Codex between Nov ‘25 and Feb ‘26, which were trained with heavy reinforcement learning on long codi…

    Definitely. But I think the nature of that impact is not entirely clear. In the legal context, LLMs are also hallucinating extensively, citing made up case law, etc. It’s not yet c…

    Fixing a bug is in the wheelhouse of AI to the extent that the fix can be verified — since there is a clear objective function. The real question is whether there are unintended si…

    +1 This is the core question to ask.

    Comment #47553861

    I suspect that for a nation-state type threat actor, this wouldn’t be much of a deterrent. Any type of reputation system like this would work to a point until motivated threat acto…

    It does mean something to me, but perhaps not as profound as whoever coined the term was hoping!

    Thanks for sharing. Can’t believe he’s still teaching that class after two and a half decades!
