Of course.

I wonder how we managed way back in the day to produce systems that can handle untrusted inputs and reliably instruct a dumb-as-bricks CPU what to do based on those inputs. Must have been black magic lost to the mists of time.

>reliably instruct a dumb-as-bricks CPU

Yeah...a "dumb as bricks CPU", which is obviously something frontier llms are demonstrably not. Like, you're not making any sense here. None of the things that make this possible with CPUs is remotely relevant here, and the fact that you don't seem to understand this but act so smug is strange.

  • > Yeah...a "dumb as bricks CPU", which is obviously something frontier llms are demonstrably not.

    Just as the immense amount of scaffolding around the dumb-as-bricks CPU enables extremely sophisticated and useful things to be done with that pile of fused sand and copper, the immense amount of scaffolding around the dumb-as-bricks LLM enables very sophisticated and useful things to be done with that pile of linear algebra.

    Don't confuse the infrastructure that makes the stupid bit in the middle actually useful with the stupid bit in the middle.

    • LLMs are not the "stupid bit in the middle." They're almost the entire value. LLMs were wildly useful before any sort of scaffolding. They are not "dumb as bricks". They are highly capable, flexible, intelligent prediction machines.

      The only one confused here is you, and you've still not managed to tell us in an actionable way how exactly CPU scaffolding is relevant here. Tell us, if it's so easy, or make your millions selling it. We're all waiting.

      I'll give you a hint. CPUs never had to interpret the meaning of arbitrary content in order to do their job, and LLMs do.

If you can figure out how to separate instructions from data in LLMs you should ship the first agent system that's guaranteed protected against prompt injection. You'll make millions.

  • Why not just have distinct input streams, or a metadata stream which annotates text in the main stream according to priority in case of conflicting instructions?

    • Because nobody has figured out how to make that work 100% reliably yet.

      The current approach is to use delimiters that are special tokens that can't be represented in regular text: https://github.com/openai/harmony/blob/main/docs/format.md#s...

      Then you train your model to take those tokens into account.

      Which sounds promising... until you see results like this one: https://arxiv.org/abs/2603.12277

      > We trace prompt injection to role confusion: models perceive the source of text from how it sounds, not its labeled role. A command hidden in a webpage hijacks an agent simply because it sounds like <user> text, despite its <tool> label

  • It’s pretty simple. Both the intake and the output of the LLMs are data and they shouldn’t drive an actuator system (their output shouldn’t be instruction). We already have the same structure in organizations where there’s an army of analysts for information gathering and processing and then the executive department tasked with decisions.

    We have even observed that the most effective LLM usage is when paired with an expert in charge of the goals. Dark factory and other automated harnesses (specs engineering and what not) seem to be a dead end. The most impactful approach to this date is an interactive conversation as a succession of small and verifiable tasks.

  • Yeah, this matches what I've learned over the past couple of years from reading some of your blog posts and reading your interactions in comment threads here and elsewhere. You're a politician, rather than a truthseeker.

    The absolute most I've seen from you in response to an extensive teardown of your argument, supporting evidence, and subsequent conversational judo was a «Wow. That was well phrased.» and no subsequent change in your publicly-expressed opinions.

    I'd do more than gesture at the relevant lesson taught to us by Google Fiber, Tesla, SpaceX, etc., but you'd not be publicly moved, so it's a waste of time.

    • > You're a politician, rather than a truthseeker.

      Justify that.

      Also, which "extensive teardown" are you talking about there?
