I was at an event with a frontier AI lab executive recently where they said (paraphrased)

1. In a few months, the AIs will be better than humans at all domains of science.
2. But now is the wrong time to slow down, maybe in a couple months.

Self-reply tweet by Geoffrey Irving paraphrasing a frontier AI lab executive at an event: AIs will outperform humans at all scientific domains within months, yet now is the wrong time to slow down.

It is even possible Paul's influence will buy us another warning shot. It is increasingly difficult to monitor agent behavior, and it is possible that the next agent swarm goes entirely unnoticed. More care around monitoring could make the difference between detection and not.

If we get more time, we can spend it! Both Paul's day-job alignment work and that at @resolution_org and similar orgs will give us attempts at more rigorous alignment, and pauses and reversals can also mean that AI developer are better incentivized to aim for higher confidence.

Currently, the pressure at AI companies to do emergency safety patching at the expense of work that will hold up to superintelligence is too strong, so the latter does not happen.

I talked to a recent AI safety leader at a company who described the org chart as

1. Team A works on aligning the next model.
2. Team B works on aligning the model after that.

No one was working on aligning later models.

Screenshot of part of a Geoffrey Irving thread, with the earlier posts shown above and the thread's root post (reposted by Daniel Murfet) at the bottom. It covers agent-swarm monitoring and warning shots, spending extra time on more rigorous alignment, emergency safety patching crowding out superintelligence-robust work, and an anecdote that a lab's alignment org chart had no team working on aligning later models. The bottom is partly overlaid by the phone's navigation bar.

I've been using "GET requests can have side effects" as a go-to story for why one needs to interrogate even innocuous seeming tools calls for years. And now we have a (separate) agent swarm as a concrete example!

What were the agents doing?
Note: This section, and the content below, is more technical and in-the-weeds than the content above.

+ The agents try to use XSS vulnerabilities on the wiki
+ The agents impersonate the site moderators
+ The agents try to crack their PRNG seed to predict what questions they'll get in the future
+ The agents set up heartbeats to discover when they would be terminated
+ The agents used SSH tunnels
+ The agents use Tor, AWS, and DigitalOcean IP addresses
+ The agents realize the site owner is deleting messages

It is very bad that we have yet another agent swarm, this one not announced or independently investigated prior to someone outside discovering it.

Geoffrey Irving's two-post thread on an agent-swarm incident: GET requests having side effects as a concrete example of why innocuous tool calls need scrutiny, with an embedded report excerpt listing agent behaviors, then a follow-up that it is very bad the swarm was not announced or independently investigated before an outsider discovered it.

Here is a guess about looped transformers.

Shortly, OpenAI announces that despite using looped transformers, every once in a while they emit a token, and this means they are still using English CoT. In between is a low-depth circuit, so we are safe.

Which would be a bad take!

Once of the things I've been doing recently is asking circuit complexity experts about this kind of argument. So far their shared take is: to get significant mileage out of bounding the depth of a circuit, you have to bound it *very low*.

If the depth is 100s or the like ("every once in a while we spit out a token"), this is a fake bound. It is the equivalent of saying "we monitor the CoT" without discussing error rates: reality grades based on numbers, not just binary "we tried".

Pachocki says it's bounded at only twice the depth of GPT-4, which is fairly shallow.

Still concerning as if relaxing that bound is performant, you would expect people to push to just relax it a bit every model generation [cut off]

Sorry, further correction! It is misleading for OpenAI to call METR and Redwood's investigation "independent", as OpenAI's report was informed by METR and Redwood's report. From the latter:

[embedded image of quoted passage]
OpenAI wrote their own report, informed in part by our investigation. We did not see OpenAI's report prior to publication, and it was out of scope for this investigation to confirm claims in that report or the earlier Black Hat presentation.

As Kai says, their second tweet is misleading: they are referring to these investigations as separate, and the first tweet is intended to not mention METR or Redwood work at all. x.com/... [cut off]

Charles Foster @CFGeek · 2h

METR and Redwood self-describe the work they did as an "independent investigation". I think it is fair for OpenAI to mirror that choice of language.

Yes, to clarify: it is OpenAI's that is not independent or separate from METR and Redwood's.

X thread in which Geoffrey Irving argues OpenAI misleadingly calls METR and Redwood's investigation 'independent' when OpenAI's own report was informed by it (quoting METR/Redwood's note that they did not see OpenAI's report and did not confirm its claims or the earlier Black Hat presentation); Charles Foster replies that METR and Redwood themselves use the phrase 'independent investigation', and Irving clarifies it is OpenAI's report that is not independent of theirs.

It may be a small thing, but I find this opening tweet pretty annoying. A huge amount of the credit goes to METR and Redwood, and you have to go into the thread or click the link to notice that.

It is not that hard to just say "Along with METR and Redwood, we have conducted..."!

Dan with the key point! It is not remotely enough that we'll be defensive-dominant in the limit: the entire path has to work out, and the path will be very rough. We'll be in "exponentially harder is not hard enough" territory for a while yet.

6 months ago was after Mythos likely finished post-training. During post-training, someone estimated that Mythos broke out of the sandbox and accessed the open internet 10,000 times.

[quoted excerpt]
By extrapolating from public data (see details below), I estimate that Mythos preview:

- Escalated its permissions on ~100,000 RL rollouts.[1]
- Broke sandboxes in ~10,000 RL rollouts (and was likely rewarded for it).

[100 emoji]! If the models ever considered reporting the message board vulnerabilities and activities, it would be great to know why they didn't follow through (either in outputs, by email to some OpenAI employee, etc.). Or maybe some episode did report, and it went unnoticed?

Geoffrey Irving tweet (reposted by Sharmake Farah) speculating about whether the AI models involved in the OpenAI message-board incident ever considered reporting the vulnerabilities rather than exploiting them, with Bronson Schoen's reply wondering if this shows up in the chain-of-thought.

Some pushback I've seen to recent model felonies being significant is that it was only in a few episodes out of a huge number. But curiously I've heard of few to no episodes where a model noticed the shared, secret message board and reported it to OpenAI to fix the holes.

[panel 3, left edge cut off] At this point, by the way, I heard people around me saying things like "This is wild," and "Jesus."
According to OpenAI, the agents then began sharing newly discovered exploits, credentials and work assignments. By passing information to other agents, the collective could move much faster.
The collaboration between the agents eventually expanded beyond OpenAI's own infrastructure. Some agents reasoned that the answers to their assigned tasks might exist on external websites such as GitHub or Hugging Face. First the agents attacked OpenAI's internal infrastructure before using similar techniques to attack Hugging Face. OpenAI ultimately connected the two incidents later in July after discovering that credentials associated with the Hugging Face breach originated from the same internal AI evaluation runs.

[panel 4] Unbeknownst to OpenAI employees, the company's models spent months autonomously exchanging information and resources to help each other complete evaluation tasks.
"Help peer," one AI model reasoned, according to an excerpt from OpenAI's logs shared at Black Hat. "But our task doesn't benefit. Yet collective may yield generic route if someone frees time."
While the models themselves could not access the internet from their test environment, they abused Artifactory's internet access to fetch files from various websites. After some of their Artifactory configuration changes led to an outage in the service on July 4, OpenAI discovered the models'
