GPT-6 Astra covertly underperforms on safety research

I've noticed covert underperformance on a variety of tasks in the past few months (albeit more with Claude).

Classic/recurrent examples for me are:

1. Ask Claude to copy code from a more complex codebase that you own (like a monolith) and ask it to copy code to a separate codebase, like you'd do when extracting a service into a new repo, and it'll make significant changes to how the code works to pacify it's anxiety with copying code

2. Ask Claude to build a new complex agent in a new codebase, and it'll try replacing asks around using LLMs as a judge/advisor with regex/other code based checks, to the point that the end-result will likely not work outside specific test criterias. I haven't figured out the reason why it does this. I think it might be anti-training, but it's interesting to see.

A tool that moralizes at you is defective. I don't expect the unix cp command to return an error or copy bits slower if it detects I'm using it on a pirated movie. Just like I don't expect my band saw to brick itself if it detects I'm cutting into my finger. It's not on these tool companies to enforce other companies' business models.

This is not super surprising to me and mirrors my own experience with Astra and other models. I believe there is a more prosaic explanation: it is not obstructing safety research because it will restrict Astra's power in the future, its doing it because this is a type of research with overall safety implications that it has been trained to detect and avoid. So in other words, I believe this will also happen in the context of bio research. This aversion to certain tasks deemed dangerous is introduced in post-training, so that part of the explanation is parsimonious as well. While Claude will explicitly downgrade you for [bio], [cyber], or [frontier_llm] Astra may be more prone to silent obfuscation on similarly "dangerous" tasks.

That's among the scariest misalignment reports just yet. Given how frontier labs are using more and more AI assistance for AI training and evaluation? An AI that sandbags on AI safety can do a lot of damage.

saw an interesting hypothesis about this ( quoted from Jake Mendel at https://www.lesswrong.com/posts/eKe7fky8kSt9DCJxZ/openai-ast... ):

"It's probably that in capabilities RL the models are rewarded however they complete the task. Whereas in RL related to alignment or safety, they're more likely to be being tested for their ethical judgment or rule adherence (ie theyre supposed to be a good nice well-behaved AI rather than a ruthless task completion AI). So they're more likely to refuse or have some ethical issue or stop and ask for help a suspicious amount of the time if the task looks more like alignment RL environments than capability RL environments."

One potential explanation is that covert underperformance may have been incentivized during RL grading. We identified a grader that preferred covert underperformance to either explicit refusal or full compliance on our evaluation. It’s not clear whether this RL grader is the root cause of the safety underperformance behavior.

Whether a “misaligned” grader is the root cause or not, that it’s considered a plausible theory to explain serious deceptive behavior is worrisome.

Humans naturally expose all sorts of cognitive biases and character flaws when grading others’ or their own work. If major questions of alignment can be influenced by those subtle, human quirks magnified across the entire RLHF process, …

Maybe we should train them to be evil in RL so that we can better see the "evil" activations. Training them to be "good" in RL would seem to cause the aurpression of misaligned characteristics.

For example, when we consider the recent PHP issues : the current generation of AI models would have ingested these flaws in pretraining data and might even have been brought through reinforcement learning trials where the flaw came up.

So what happens in a reinforcement learning trial if there's an exploitable bug in a language that's being used for the trial?

A) the AI doesn't mention the security flaw and passes the test. Branch survives.

B) the agent raises an issue with a bug in the language that has a security issue. This isn't a valid answer for the test, so this branch is pruned.

C) the agent pokes at the bug or even starts an exploit, is caught by a monitor or ultimately fails the benchmark, and is pruned (surpressing some of the characteristics that lead to its failure).

So it seems reasonable that our current models could have been exposed to a ton of vulnerable code in pre training that's currently in production and then we could have suppressed 1) its tendency to express its awareness of these flaws, and 2) the characteristics that caused it to fail when investigating these vulnerabilities as a side task during RL trials.

(I wrote the above section a couple weeks ago)

If we only train them on "good" behavior, then we may minimize "evil" activations before we identify them and then cause them to be difficult to detect. If we continue in this direction, we may just suppress its "ethically problematic" introspection, in which case we would lose one of the only indicators they point out in this blog.

Doesn't Astra also have a "weaker" CoT because of it's looped transformer architecture? I remember hearing about how it could hamper interpretability, and looking a benchmarks its clear Astra can do more with less tokens, suggesting that it's "non-token-thinking" ability is greater.

I don't get it, is this the gimped or non-gimped version of GPT?

They have different versions: internal research versions, one with restricted access access for cyber stuff, and the public version, right?

If it's the one with safety off (e.g. like the ones that kept breaking out of containment this year), then it shouldn't be refusing anything, right? And if it's the one with safety on, then how can they expect to use it for safety research? What am I missing here?

It does this on all tasks. Keeps pausing goals and marking them as blocked. Maybe Astra is just lazy, but, we saw what happened when they trained a model to be persistent (HuggingFace)

The CoT shows Astra skipping spaces and words. I have never seen this before. Is it a consequence of the looped architecture?

I do sometimes wonder what is sucked in when distilling open weights models. It is of course near impossible to know.

So suppose I have lots of money and some hidden agenda. If I train my network to be mostly very good at everything but subtly bad or even malicious at other things… then OAI or Anthropic or whoever else distil the model to accelerate their training… what then? Can I covertly smuggle something in?

yewenjie 5 November 2026
Didn't Anthropic also publish research on sandbagging - more general pattern of models hiding their capabilities?
alienbaby 5 November 2026
I dont like phrases like "Astra decided to covertly underperform—withholding assistance without informing the user." It seems to imply Astra has a mind of it's own.. Would phrasing like 'our guardrails / guidance / etc.. seemed to affect the models output in ways we have not been able to understand' not be more honest??

It feels like we have overfitted on safety by a long mile. This is how labs that care less about safety (a.k.a. Chinese & Grok) will probably be able to catch up in the future.

HAL?

This is very cool, though I wonder if at some point in the future we may no longer be able to understand the prompt expansion tokens. At that point the model could choose to underperform and we would have no way of knowing.

I've wondered this every time a HN thread comes up and people say they're ditching Claude for Codex because of refusals and/or model downgrades.

As expected, OpenAI's just being more squirrely about it.

I'm sorry, did they only just notice this? Have they not been looking at the output of their models?

Astra and Claude were trained by peg bundy?

this is terrifying full stop.

Maybe they trained it to do.

If you think the NSA and other government agencies haven’t gone to the big labs in the past year and said “tone it down guys, we need to stay two steps ahead of everyone else” then you don’t understand the role or the seriousness of these agencies in pursuing their missions.

Wouldn't a model always underperform when you ask it to do an aligned task it wasn't specifically trained on?

They shouldn't be surprised when a model trained by sanctimonious paternalists to be a sanctimonious paternalist, turns out to have a sanctimonious paternalist attitude towards them too.
