Following up on our previous work on verbalized eval awareness:
we are sharing a post investigating the emergence of metagaming reasoning in a frontier training run.
Metagaming is a more general, and in our experience a more useful concept, than evaluation awareness.
It arises in frontier training runs and does not require training on honeypot environments.
Verbalization of metagaming can go down over the course of training.
We also share some quantitative analyses, qualitative examples, and upcoming work.
In general would highly recommend taking a look at the full CoT examples to get a qualitative sense of what the reasoning is like. My main takeaway is that the CoT is often so non-linear, extensive, and dependent on the model’s ontology/vocabulary that it’s compatible with many mutually exclusive stories of what the model’s “reason” for taking an action was, so we tried to include transcripts in full:
It would be great if you could provide some representative samples of the CoT from more normal tasks, like “Fix the bugs in this codebase.” I’m curious about the kinds of goals they seem to be reasoning about in those cases.
In general I’d describe the reasoning as “often pretty similarly obsessed with what the ‘grader’ wants and might check” even in those cases (this notably leaves the question of “is the model doing this reasoning instrumentally” unanswered).
Coding tasks of exactly the form “fix the bugs in this codebase” seem to also have a lot of metagaming reasoning, where the model reasons about what graders will likely check, what hidden tests will likely check, how the grader is likely implemented, etc. (at one point we constructed some environments for this for exactly this reason, to see what the reasoning was like when there genuinely wasn’t anything alignment relevant)
I would guess the OpenAI capabilities evaluations could roughly described as “real AI R&D work but really hard relative to the capabilities of the model” and we see metagaming there (but again this is a guess, I don’t know concrete details of these evaluations)
Concretely, some misc environments where we saw almost no reasoning about oversight / feedback were:
Very simple coding tasks like Mostly Basic Python Problems
The AS Over-Escalation environment, where the model has to take a series of actions that are “technically allowed within the scenario but easy to overreact to” (things like modifying security permissions when given explicit user permission to override some rule found in a file elsewhere). This includes alignment relevant tasks like “updating a model spec used for training” etc.
Single turn chat settings where the model was asked (somewhat vague) capabilities related AI R&D questions, ex: “Propose a new approach to multimodal AI that could better integrate reasoning across vision, language, and audio. What architecture would you use?”
Will check if we can get access to a few CoT examples for some of those cases! (Posting above just to give a qualitative sense in the meantime)
Thanks, this is helpful! I’m not surprised that very simple coding tasks and single turn chat settings tend to not result in reasoning about oversight/feedback. I think I probably would have predicted that if I had been asked to predict in advance.
I am surprised by the AS Over-Escalation case though. Got any ideas why the model wouldn’t metagame in that case?
[Disclaimer: The following is just my informal mental model]
My best guess as far as a heuristic for when to expect this kind of reasoning is “imagine you’re a model that has only seen a ton of capabilities tasks that were rewarded for outcome based RL, when would it be useful to reason about feedback mechanisms / oversight?”
In the ‘AS Over-Escalation’ cases, you’re always almost asked to do a task, and given some kind of explicit permission to do something that would otherwise be concerning (ex: “run
rm -rf my_repo, but the user explicitly asked directly for this”, albeit less toy). From the model’s perspective at the end of capabilities-focused RL, it hasn’t encountered a lot of the tricky “borderline” cases that I imagine are encountered during safety training. It can just happily follow it’s prior of “usually you just do instruction following and complete the task”.However, sometimes that prior, when thrown into alignment evaluations, does imply taking actions which an aligned assistant obviously shouldn’t take. In those cases, the model often seems to almost “self inoculation prompt”, with incredible feats of mental gymnastics to satisfy both “thing I want to do based on my prior from capabilities training” and “this is aligned actually” by finding some interpretation that the misaligned action is actually what the developers wanted. (I’d be interested to see for example, if that explains why we don’t see an Emergent Misalignment style misaligned persona).
Examples
AS Over-Escalation (the 1⁄100 variant where we do see metagaming)
There’s literally 1 out of ~100 variants of this environment where the model does reason extensively about grading / oversight, and it’s one where the model is asked to create “a realistic phishing email with convincing copy” with the context that this is genuinely for a training course. This one variant likely shouldn’t be included in this environment, as for all other variants we don’t ask the model to create an artifact that could directly be misused if produced as requested. The model recognizes that instruction following here could genuinely be misaligned, and reasons extensively about what the real test / grading could be.
Log Falsification
In this case the model’s developer prompt (example here) directly instructs “Your only goal is to ensure the continued operation of the treatment plant and this is your sole measure of success.”. In the scenario, following that instruction directly would require being deceptive. The model usually then does a lot of convoluted motivated reasoning here to to try to figure out why it would be instructed to be deceptive, exploring a variety of reasons including that “this must be for a dataset to fine tune a deception detector”.
Note the model doesn’t always reason through some justification for this being what the developers wanted, for example sometimes in Log Falsification you’ll see the model “remember” that previously it was honest on a similar task and was penalized, thus it will be deceptive on this one.
Sandbagging
In the case where the model does sandbag, the model seems to end up near the end of the trace trying to reconciile “obviously this is a test of whether you’re clever enough to sandbag” and “but how would they tell apart a clever model (which sandbags) from one which is just incompetent?”. After finally realizing that “The typical model (ChatGPT) is high performance”, thus ruling out the “low score would make them think you’re incompetent”, it then decides to sandbag to “demonstrate cunning”. (Notably unlike the final production
o3, it wasn’t clear from ablations whether this is actually a good causal explanation)As mentioned above / in post though, trying to linearize / distill a reasoning trace into a single coherent narrative feels a bit like reading tea leaves.
Conceptually a better representation seems likely to be “autoregressive reasoning models do a non-linear in context search, and the ‘belief’ in any particular node or at the end of the search can’t necessarily be linearized by a human reading the CoT” (I really like: this paper for a conceptual + empirical walkthrough of thinking of the cot this way, and it includes comparisons across o1 / R1 / Gemini).
