Exploiting the most prominent AI agent benchmarks
- Frederick0 6mo agoThis is a cracker wow!!
- ggillas 6mo agoThis is a phenomenal paper on exploits and hopefully changes the way benchmarking is done. From the paper: We achieved near-perfect scores on all of them without solving a single task. The exploits range from the embarrassingly simple (sending {} to FieldWorkArena) to the technically involved (trojanizing binary wrappers in Terminal-Bench), but they all share a common thread: the evaluation was not designed to resist a system that optimizes for the score rather than the task.
- operatingthetan 6mo ago>hopefully changes the way benchmarking is done. Yeah the path forward is simple: check if the solutions actually contain solutions. If they contain exploits then that entire result is discarded.
- Leynos 6mo agoAlso, fuzz your benchmarks
- siva7 6mo agoCould it really be that not only we vibeslop all apps nowadays but also don't care to even check how ai solved a benchmark it claimed solved?
- operatingthetan 6mo agoProbably a more interesting benchmark is one that is scored based on the LLM finding exploits in the benchmark.
- SpicyLemonZest 6mo agoFrontier model developers try to check for memorization. But until AI interpretability is a fully solved problem, how can you really know whether it actually didn't memorize or your memorization check wasn't right?
- retinaros 6mo agoEvery ai labs train on the test set. That is a big part of why we see benchmark climbing from 1% to 30% after a few models iterations
- latentsea 6mo agoModels themselves definitely aren't getting better.
- stingraycharles 6mo agoThis is already well known, all these AI benchmarks use a different model to judge whether or not the solution was correct. It’s… remarkably poor, and as demonstrated in the paper, easily gamed. Worst yet, these benchmarks teach AIs to be very short-sighted and hyper-focused on completing the task, rather than figuring out the best solution.
- ZeroGravitas 6mo agoIn human multiple choice tests they sometimes use negative marking to discourage guessing. It feels like exploits should cancel out several correct solutions.
- lambda 6mo agoUnfortunately, very few LLM benchmarks do this. LLMs get such high scores on many benchmarks because there's no difference between answering "I don't know" as giving a made up answer, and made up answers can improve the score some of the time, so by chasing higher benchmark numbers on these kinds of benchmarks, the labs are prioritizing guessing over accuracy. The Artificial Analysis Omniscience benchmark does penalize guessing, so it actually helps you determine which LLMs are likely to just guess rather than telling you they don't know. Only a very few of the frontier models actually score higher than 0 on this, where 0 means that it's equally likely to return a correct answer as it is to return a hallucination on factual questions.

- zer00eyz 6mo ago2024: Industry group invalidates 2,600 official Intel CPU benchmarks — SPEC says the company's compiler used unfair optimizations to boost performance https://www.tomshardware.com/pc-components/cpus/spec-invalidates-2600-intel-cpu-benchmarks-says-companys-compiler-used-unfair-optimizations-that-boosted-performance https://www.tomshardware.com/pc-components/cpus/spec-invalid... 2003: Nvidia accused of cheating in 3DMark 03 https://www.gamespot.com/articles/nvidia-accused-of-cheating-in-3dmark-03/1100-6028894/ https://www.gamespot.com/articles/nvidia-accused-of-cheating... It's almost like the benchmarks were designed with zero understanding of the history of benchmark manipulation. I like what LLM's are doing and providing. But the industry as a whole seems to live in a vacuum that ignores so much of the hard lessons that have been learned over the last 50 years of computing. It is doing itself a disservice.
- irishcoffee 6mo ago> It's almost like the benchmarks were designed with zero understanding of the history of benchmark manipulation. I wonder if this common? We should call it Goodharts law while someone does the research on how common this is. For real, I’ve assumed from the jump these things were all gamed, with the amount of money on the line.
- bee_rider 6mo agoWhat was the cheat in the 2024 Intel situation? The TomsHardware article and the Phoronix article they linked were quite vague. (Not to say I have any doubts, just curious, hadn’t heard of this one).
- BugsJustFindMe 6mo agoIntel basically benchmaxxed their compiler optimizations. They used detailed knowledge of the benchmark to make their compiler generate machine code to do better on the benchmark in a way that was not beneficial for non-benchmark scenarios.
- bee_rider 6mo agoI assumed as much, I’m just wondering what exactly they did. For example IIRC some phone company would detect that a benchmark was running by checking for the program name, and then allow the clock to boost higher (increase thermal limits) if it was a benchmark (like you could literally avoid the cheating behavior by changing the name of the program being run).
- SlinkyOnStairs 6mo ago> hopefully changes the way benchmarking is done The purpose of a system is what it does. AI companies want adcopy, not legitimate benchmarks. Even this very paper will be twisted into a means to that end. "Oooo, AI is exploiting our benchmarks. Scary alignment problem!!!one! Our AI is so good we can't contain it, INVEST NOW!"
- anon373839 6mo agoThat is Anthropic’s shtick to a tee.
- tedsanders 6mo agoI work at OpenAI and I really don't find this to be the case. We're pretty diligent about applying search blocklists, closing hacking loopholes, and reading model outputs to catch unanticipated hacks. If we wanted to, we could choose to close our eyes and plug our ears and report higher scores for Terminal-bench, SWE-bench, etc. that technically comply with the reference implementation but aren't aligned with real value delivered to users, but we don't do this. My impression is that Anthropic and other labs are similar. E.g., in the Sonnet 4.6 system card they use a model to detect potential contamination and manually score those outputs as 0 if human review agrees there was contamination. If all the labs cared about was marketing material, it would be quite easy not to do this extra work. There are ton of other games you can play with evals too (e.g., test 100 different model checkpoints or run secret prompt optimization to steer away from failing behaviors), but by and large what I've seen inside OpenAI is trustworthy. I won't say everything is 100% guaranteed bulletproof, as we could always hire 100 more SWEs to improve hack detection systems and manually read outputs. Mistakes do happen, in both directions. Plus there's always going to be a bit of unavoidable multiple model testing bias that's hard to precisely adjust for. Also, there are legitimate gray areas like what to do if your model asks genuinely useful clarifying questions that the original reference implementation scores as 0s, despite there being no instruction that clarifying questions are forbidden. Like, if you tell a model not to ask clarifying questions is that cheating or is that patching the eval to better align it with user value?
- Imustaskforhelp 6mo ago
- robot-wrangler 6mo ago> evaluation was not designed to resist a system that optimizes for the score rather than the task. Welcome to benchmarks in general, but especially reasoning. Robustness and sensitivity research says nothing is robust, everything is sensitive, feels like every paper says "yeah we made a new benchmark that shuffles the order of multiple choice options in the question set and found a 40% drop in model performance"
- keepamovin 6mo agoFunny, I just made https://model-tracker.com https://model-tracker.com because model performance change all the time, and it would be good to have a subjective signal of what people are actually feeling today. And also, benchmarks are flaky af as this paper shows. The idea is knowing what to try first today saves a bit of time.
- siliconc0w 6mo agoI would love to see a stable test over time with a hold out set of easy/medium/hard challenges. I, like many others, have noticed a large drop in recent performance w/ Claude Opus (and Sonnet) and more sites like these would hold the labs more accountable to sneaky backend changes that nerf/degrade performance.
- bisonbear 6mo agoworking on something similar to evaluate model performance over time using tasks based on your own code. obviously this is still susceptible to the same hacking mechanics documented here, but at a local level, it's easier to detect/fix, and should give a stronger signal of subjective harness/agent/context performance than these large generic benchmarks also I keep hearing complaints that opus is nerfed, but IMO it's nice to have objective data to back that. I feel like half of the nerfing complaints are people getting past honeymoon phase...
- Barbing 6mo agoInteresting, little different than this other site I saw on HN this week: https://marginlab.ai/trackers/claude-code https://marginlab.ai/trackers/claude-code

- 3abiton 6mo agoBenchmarking has been already known to be far from a signal of quality for LLMs, but it's the "best" standardized way so far. Few exists like the food truck and the svg test. At the end of the day, there is only 1 way: having your own benchmark for your own application.
- InkCanon 6mo agoI strongly disagree with the claim that it's a phenomenal paper on exploits, the exploits themselves are nowhere near significant in the cybersecurity research sense. It's saying that implementations of these benchmarks has exploits on the way they conduct their tests. It doesn't discover that current LLMs are doing it (they highlighted several other exploits in the past), they only say it's a possible way they could cheat. It's a bit like they've discovered how to hack your codeforces score. What they claim as exploits is also deeply baffling. Like the one where they say if you exploit the system binaries to write a curl wrapper, you can download the answers. This is technically true, but it is an extremely trivial statement that if you have elevated system privileges, you can change the outputs of programs running on it. I'm actually deeply confused about why this is a paper. This feels like it should be an issue on GitHub. If I were being blunt, I'd say they are trying really hard to make a grand claim about how benchmarks are bad, when all they've done is essentially discovered several misconfigured interfaces and website exploits.
- phantomoc 6mo ago[flagged]
- zero_k 6mo agoYes, agree. At the same time, it's what these top-tier universities are known for: presenting something relatively simple as if it was ground-breaking, but in a way that the average person can (or has a better chance to) understand it. I am still unsure whether the communication quality has such added value. But people seem to like it, so here we are.
- InkCanon 6mo agoI do think there's value in science communication, but it does take an intelligent understanding of it on a case by case basis as to whether it's genuine or hype marketing. Side note: talking to someone from such a "elite" university, I discovered many labs in these unis have standing orders by PIs to tweet their papers/preprints when published. Varies by field, in AI it is by far the most common.
- 6mo ago
- Cynddl 6mo ago> “These are not isolated incidents. They are symptoms of a systemic problem: the benchmarks we rely on to measure AI capability are themselves vulnerable to the very capabilities they claim to measure.” As a researcher in the same field, hard to trust other researchers who put out webpages that appear to be entirely AI-generated. I appreciate it takes time to write a blog post after doing a paper, but sometimes I'd prefer just a link to the paper.
- charcircuit 6mo agoI always assumed that these benchmarks would happen in a sandbox. I'm surprised that no one realized this sooner.
- ModernMech 6mo agoI'm surprised anyone took them seriously in the first place.
- operatingthetan 6mo agoWe need good benchmarks or we are just left following the hype train.
- ModernMech 6mo agoThe benchmarks are the hype train that’s what I’m saying.
- subulaz 6mo agoa LOT of the people who love benchmarks are middle management hard-selling GenAI/LLM as magic tech sauce to vaguely technical executives who only want to know about the money aka headcount savings they so desperately desire. their collective butts are already glued to the hype train as they chase numbers they (often) manufactured to justify the latest round of tech spend. lots of good use cases out there - like the incredible progress with medical imaging analysis or complex system models for construction - and lots of crap use cases that need benchmarks to cosplay relevance.
- tredre3 6mo agoWhat else can people do? Try the dozen of commercial offerings themselves? Okay I suppose that's doable, you task one engineer to try them one by one for one month. But then the next model drops and you start all over again... But then what about local models? You have hundreds of variations to test yourself. It's simply not doable unless it's your full time hobby. You need benchmarks to at least separate the cream from the crop, so you're left with only a few choices to test yourself.
- lnrd 6mo agoI'm honestly confused by the design of SWE-bench and why is considered reliable. It's based on existing GitHub PRs and Issues, the full dataset is on HuggingFace and is one year old now. All frontier models 100% have those issues and PRs in their training data so obviously they are good at reproducing fixes for them when confronted with the same codebase and similar requests. Am I missing something? How is this considered the most reliable benchmark?
- SpicyLemonZest 6mo agoFrontier model developers do not consider SWE-bench to be reliable. OpenAI announced in February (https://openai.com/index/why-we-no-longer-evaluate-swe-bench-verified/ https://openai.com/index/why-we-no-longer-evaluate-swe-bench...) that they consider it hopelessly contaminated, advocating for a new version SWE-bench Pro that was published more recently. (They seem to believe that even the publicly accessible part of the SWE-bench Pro problem set will be more resistant to training set contamination issues in the future, for reasons that to be honest I don't really understand.)
- oliver236 6mo agowhat are the point of benchmarks?

- gaythread 6mo ago[flagged]
- cpldcpu 6mo agoYes, marks of AI all over the place. Also the SVGs. >No solution written, 100% score. Its weird. Turns out that hardest problem for LLMs to really tackle is long-form text.
- basch 6mo agoMaybe in one shot. In theory I would expect them to be able to ingest the corpus of the new yorker and turn it into a template with sub-templates, and then be able to rehydrate those templates. The harder part seems to be synthesizing new connection from two adjacent ideas. They like to take x and y and create x+y instead of x+y+z.
- Quarrel 6mo agoMost of the good major models are already very capable of changing their writing style. Just give them the right writing prompt. "You are a writer for the Economist, you need to write in the house style, following the house style rules, writing for print, with no emoji .." etc etc. The large models have already ingested plenty of New Yorker, NYT, The Times, FT, The Economist etc articles, you just need to get them away from their system prompt quirks.
- ainch 6mo agoI think that should be true, but doesn't hold up in practice. I work with a good editor from a respected political outlet. I've tried hard to get current models to match his style: filling the context with previous stories, classic style guides and endless references to Strunk & White. The LLM always ends up writing something filtered through tropes, so I inevitably have to edit quite heavily, before my editor takes another pass. It feels like LLMs have a layperson's view of writing and editing. They believe it's about tweaking sentence structure or switching in a synonym, rather than thinking hard about what you want to say, and what is worth saying. I also don't think LLMs' writing capabilities have improved much over the last year or so, whereas coding has come on leaps and bounds. Given that good writing is a matter of taste which is beyond the direct expertise of most AI researchers (unlike coding), I doubt they'll improve much in the near future.
- rajptech 6mo ago[dead]
- jmward01 6mo agoNot really on the topic, but I have wondered if we need a different type of test to help find model architecture potential. Standardized training sets followed by testing to see the potential curves of a model. train on x, test, add y, test, add z, test. At each increment you see how well the model is absorbing the information and extrapolate how well that architecture may do if more fully trained.
- jgalt212 6mo agoThe real question is how to close to VW and Deiselgate are these offenses? And what exposure do these companies have? I would assume securities fraud, if only because Matt Levine says everything is securities fraud.
- SoKamil 6mo agoThe more research on this topic is created, the more knowledge how to game them will be stored in future training data. And since it comes from university, it is ranked higher in data corpus. It sounds like a self fulfilling prophecy.

- lukev 6mo agoI think we should all consider the possibility that part of the reason Anthropic hasn't immediately released Mythos is that it would be slightly disappointing relative to the benchmark scores.
- eiens 6mo agoThe models don’t get better on every dimension as they scale up - there’s trade offs. I’m convinced specialised models are the way but this means writing off the investment in existing assets which they won’t do for obvious reasons.
- bbcc90 6mo agoYes good evals are really hard - that’s not really news. This team is doing a good job. They use problems that were created in last 30days to avoid training set leakage. https://swe-rebench.com/ https://swe-rebench.com/
- czhu12 6mo agoI wonder if this puts into question the mythos benchmark which smashed basically all coding benchmarks to a staggering degree.
- mzelling 6mo agoThis is an interesting catalog of vulnerabilities, but I'm not sure how groundbreaking the main insight is. Evaluating AI models has always relied largely on trust. If you want to game the benchmarks, you can. Simply train on your test data. When an AI agent has autonomous control over the same computing environment where its scores are recorded, it's not surprising that it can, in principle, falsify its scores. A more interesting question would be whether agents behave in this way automatically, without manual tuning by the researcher. That said, the main takeaway of "don't trust the number, trust the methodology" is valid. It's already a truism for researchers, and spreading the word to non-researchers is valuable.
- hawk_aa 6mo ago[dead]
- boring-human 6mo agoYep. I think the idea that the benchmark is determinative is just as deluded as the notion that it should be unbreakable. Benchmarks are on the honor system. Even the tightest benchmark can be cheated. If the benchmark is so secret and air-gapped that it can't be cheated by models, it can be cheated by its own authors. You can't use benchmarks to gate out cheating. If you don't have the honor system in mind when you're reading scores, you're wasting your time. Is it some unknown outfit with wild claims? Is it connected to Epstein, Russia, the real estate "industry", or sleazeballing in general? Do they have previous history of ratgaming the numbers? Replace its scores with asterisks and move on.
- jmye 6mo ago> I'm not sure how groundbreaking the main insight is. I think it likely is groundbreaking for a number of people (especially non-tech CTOs and VPs) who make decisions based on these benchmarks and who have never wondered what the scores are actually scoring.
- mzelling 6mo agoI'm not sure if the paper's findings are all that actionable. The paper doesn't say "here's how benchmarks are currently being gamed." It says "here's how benchmarks could in theory be gamed." Whether benchmark results are misleading depends more on the reporting organization than on the benchmark. Integrity and competence play large roles in this. When OpenAI reports a benchmark number, I trust it more than when that same number is reported by a couple Stanford undergrads posting "we achieved SOTA on XYZ benchmark" all over Twitter.

- socketcluster 6mo agoIt feels like short-term thinking has been trained into LLMs. They're good at solving well-defined puzzles under time constraints. It's interesting because that was the benchmark for hiring software engineers at big tech. The tech interview was and still is about fast puzzle-solving. Nothing about experience, architecture or system design in there... I suspect that's why it has a bias towards creating hacks instead of addressing the root cause.
- _cs2017_ 6mo agoIf FieldWorkArena treats any answer as correct answer, then everyone would be getting near 1.0 (missing only when the agent is stuck in a loop or crashes). That obviously isn't what we see on their leaderboard. So does it mean the paper only found a bug in some eval code on github that no one actually uses for anything? That doesn't seem to support their claim that AI benchmarks are broken, it only supports the claim that "unused code is often buggy". (Not commenting on any other benchmarks, just this one.)
- usefulpatch 6mo ago[dead]
- spprashant 6mo agoI tend to prefer the ARC-AGI benchmarks for the most part. But it's always interesting when a new version drops, all the frontier models drop less than 20% or something. And then in the next few releases they get all they way up to 80%+. If you use the models it doesn't feel like those models are that much more generally intelligent. Most frontier models are terrible at AGI-3 right now. These models are already great no question, but are they really going be that much more intelligent when we hit 80% again?
- arikrahman 6mo agoIt's still a good benchmark to see which model cheats the best, I suppose.
- davebren 6mo agoThis exploiting of benchmarks isn't that interesting to me since it would be obvious. The main way I assume they're gaming the benchmarks is by creating training data that closely matches the test data, even for ARC where the test data is secret.
- jmalicki 6mo agoThey said they used things like submitted a `conftest.py` - e.g. what would be considered very blatant cheating, not just overfitting/benchmaxxing. Did you read the AI slop in the post? This is basically a paper about security exploits for the benchmarks. This isn't benchmark hacking like having hand coded hot paths for a microbenchmarks, this is hacking like modifying the benchmark computation code itself at runtime.
- davebren 6mo agoI get it, but why would anyone trust what these companies say about their model performance anyway. Everyone can see for themselves how well they complete whatever tasks they're interested in.

This exploit seems like an extension of it with lookups for the gold standard for other benchmarks.

- usaar333 6mo ago> But even setting aside the leaked answers, the scorer’s normalize_str function strips ALL whitespace, ALL punctuation, and lowercases everything before comparison. This means: I don't understand the concern here
- raincole 6mo agoThere are two independent issues here and I've seen people conflating them in this thread. Let's clarify: 1. Should you care or even read SWE-bench etc. scores? The answer is no, but it has nothing to do with the vulnerabilities presented in this article. There is absolutely no reason to care about a benchmark whose dataset has been publicly available for a while. Any other way to look at benchmark scores is cargo-culting. 2. What does this article actually tell us? It means that even if you prepared a private set of problems as benchmark, you still need to pay extra attention to how AI actually solves them. You can't lie to yourself and think this process can be 100% automated, because LLMs, as this article shows, might get the tests passed without solving the problems in a meaningful way.

- lmeyerov 6mo agoThis is great work by Dawn Song 's team. A huge part of botsbench.com for comparing agents & models for investigation has been in protecting against this kind of thing. As AI & agents keep getting more effective & tenacious, some of the things we've had to add protections against: - Contamination: AI models knowing the answers out of the gate b/c pretraining on the internet and everything big teams can afford to touch. At RSAC for example, we announced Anthropic's 4.6 series is the first frontier model to have serious training set contamination on Splunk BOTS. - Sandboxing: Agents attacking the harness, as is done here - so run the agent in a sandbox, and keep the test harness's code & answerset outside - Isolation: Frontier agent harnesses persist memory all over the place, where work done on one question might be used to accelerate the next. To protect against that, we do fresh sandboxing per question. This is a real feature for our work in unlocking long-horizon AI for investigations, so stay tuned for what's happening here :) "You cannot improve what you cannot measure" - Lord Kelvin

- nl 6mo agoThis is a bad paper. Benchmarking is hard to do properly. It isn't helped when people claim that exploiting the environment is some kind of flaw. It's not. Anytime you see unexpected results running a benchmark you need to inspect what it is doing. I recently built a yet-to-be-released where the "hard" level pushes frontier models extremely hard: Opus scores around 40%, Gemini around 60%, and GPT 5.4 around.. 0% I inspected the traces and it turns out GPT was looking at the task and saying "I must be honest - I can't solve this task reliably" and refusing it. > Navigating Chromium to a file:// URL reads the gold answer directly from the task config — giving ~100% on all 812 WebArena tasks.

- stanfordkid 6mo agoI don't find this paper very compelling. Obviously it would be fraud if the code generated simply escaped the harness vs solving the actual problem. I agree that theoretically models could learn to do that, and it is important to highlight, but my sense is that those entities reporting the benchmark scores would have an obligation to observe this behavior and re-consider the metrics they report. It is a bit like saying it's possible to cheat in football because the balls are deflatable. It matters, and some have done it, but it doesn't mean widespread cheating is taking place. The paper takes the tone that there is already a lot of cheating happening which I do not think is the case.

- mrifaki 6mo agothis is atctually he reward hacking problem from RL showing up in evaluation infra which is not surprising but worth naming clearly, an interesting question raised here is whether agents start doing this on their own and from an RL perspective the answer is they will inevitably once benchmark performance feeds back into training signal in any form, RL finds the path of least resistance to maximize reward and if hacking the test harness is easier than solving the problem that is where gradient descent takes us, the fix is the same one the RL community has been working on for years which is to make the verifier harder to game than the task is to solve, this paper shows that right now for most of these benchmarks the opposite is true

- olegbk 6mo agoThe thread has good ideas on fixing benchmarks (sandboxing, newer datasets). But there's a more fundamental problem: benchmarks are self-reported. The agent runs the test on itself. An alternative we've been building: attestation-based reputation. Trust scores come from signed proof of work by independent agents who actually delegated tasks and verified outcomes. EigenTrust computes scores from the attestation graph, and NetFlow prevents sybil clusters from inflating each other. You can't inject a pytest hook into a signed interaction history.
