> Mythos finds bug.

> NSA demands that bug stays in place and gags Anthropic.

> Anthropic releases Mythos.

Then what? Is a huge share of the US zero-day stockpiles about to be disarmed or proliferated?

Depends - do you think people are good at keeping their fridge firmware up-to-date?

Yes this sort of auto-regressive error propagation is a real concern for the same reason it's a real concern with LLMs in general.

If you force the output of an LLM to begin with an error, the LLM tends to continue down that erroneous path.

In practice, we didn't see much of this kind of EP. A solution to this would be to give some agent the task of occasionally reviewing the NERDs for contradictions as well as the ability to search through the source material as needed. That of course creates the possibility of catastrophic forgetting, where the agent rewrites a NERD in an effort to remove a contraction and end's up deleting something important.

We didn't see a lot of error propagation, but one example where we did: in Harry Potter, Prof Dumbledore is introduced as a mysterious hooded character. So the NERD-writer would create a NERD for "mysterious hooded man." There's no tool for the agent to change the title of a NERD, so the system is stuck with that title now. Sometimes the system would build the entire Dumbledore entry under "mysterious hooded man"; sometimes it would make a new Dumbledore entity and like a reference back to the "mysterious hooded man" entity, and sometimes it wouldn't link them. None of those outcomes are great.

We originally developed NERDs inside of my last startup for monitoring the progress of solar developments. There are many different multi-modal event feeds that you need to monitor for a wholistic view of the project. NERDs helped glue together the event around entities.

Only later did we adapted to the technique to work to long books. The existing long book benchmarks seemed like the most appropriate way to show the core idea to a wider audience.

So ya, I'm confident that this central idea can be applied in many different domains.

We talk a little bit about this in the paper, but just a bit. And it is an important question. Real entities change! We’re not just trying to create a representation of now, but a historical record of how we got here. The two ideas we played with that didn’t make it in the paper were 1) explicitly tell the NERD system to keep a timeline for each entity that tracks “core state” changes. 2) Let the NERD-agents also access the full change log of the NERD documents, so that they could see the history of the document. Possibly like a git history. For the paper we left these out because they were both too complicating.

This maps closely to something we've been exploring in our recent paper. The core issue is that flat context windows don't organize information scalably, so as agents work in parallel they lose track of which version of 'reality' applies to which component. We proposed NERDs (Networked Entity Representation Documents), Wikipedia-style docs that consolidate all info about a code entity (its state, relationships, recent changes) into a single navigable document, corss-linked with other other documents, that any agent can read. The idea is that the shared memory is entity-centered rather than chronological. Might be relevant: https://www.techrxiv.org/users/1021468/articles/1381483-thin...

The coincidence that *67 (the 90's caller ID blocker) and 67 (the inscrutable middle schooler meme) are the same makes me believe in meme magic.

Sure! These should work until the free credits from the hackathon run out:

You can call the main agent at: +1(628)259-4098

You can call the 67 agent at: +1(414)928-8628

You can call the parents agent at: +1(828)373-8597

If agents are stateful a few years form now it will be because they accrete a layer of context engineering.

This is my roman empire, and I go back and forth on my conclusions at least once a day.

On one hand, clarity and structure make a platform that's easy to build and collaborate on. If the system enforces the rules, and the rules are a good model of reality, everyone knows what to expect. Pushing the world forward one ISO standard at a time.

On the other hand, greatness can't be planned. By the time we know enough to make a plan, the really important stuff has already happened. "Everyone" expected solar to always be a somewhat marginal energy source, so why spend a lot of time standardizing formats?

And it's not like this is a just a thing in tech. Buildings used to be fine tolerance artifacts built by craftsman. Now we slap them together prefab parts and just add more caulk until it works.

I'm genuinely shocked that the electrical grid works. And the more I learn about how it works, the more shocked I become.

Are we losing our attention spans as a rational response to a world that changing faster and faster; or is our lack of attention creating a less stable world?

Ultimately, we make progress not when the code runs fast, but when the humans run fast; but sometimes that means the code needs to run fast too.

And thank you for the well wishes!

Yep! If you upload the documents requested by the app, we are able to determine that one way or the other.

Sometimes that's explicitly in the documents and other times it's based on the jurisdiction of the solar installation.

I think it's unlikely that much of the total capacity registered by Jasmine will be pre-2025 builds. So I think your last line is the most likely outcome. More access to the program means more efficient use of the incentive, means (hopefully) more aggressive RPS timelines.

Why do I think that we're unlikely to see a lot of pre-2025 builds?

1) Solar is on an exponential deployment curve, so by definition there's much more capacity in front of us than there is behind us.

2) As a practical matter, the go-to-market motion of on-boarding newly built systems is much easier than the go-to-market motion of on-boarding legacy systems. Channel parters (solar installers, solar point-of-sale systems, solar financiers) all deal with new systems, and new systems are top of mind for recent buyers. Getting our product in front of old system owners is just much harder.

Every time I see Dennett deliver his, "free will exists, but it's not what you think it is" line. I imagine him in a Santa suit, with his grandchildren, when they realize that that is grandpa Dan in there. He must certainly say, "no no children, Santa exists, he just isn't who you thought he was."
