I did some tests. I found it interesting that in the reasoning content the model identifies itself as Kimi by moonshot and sometimes it assumes ChatGPT as identity. Then sometimes it references the need to be approved by "the evaluator", other times it references global system guidelines / moonshot guidelines, and something about an phantom instruction line being "you are an assistant responding in an API" or something like that.

perhaps a simpler explanation; that kimi occasionally proxies through to ChatGPT. Possibly for A/B testing, or to gather data for training purposes.

Fascinating that we’re converging on AI safety and alignment in time across jurisdictions. The cybersecurity approach taken here is interesting because should the model be opened it’s still not dealignable because it just doesn’t know enough.

The slow warming of the water is a good approach. I’ve been using abliteration.ai’s cybersecurity models to pentest my own software and it produces much more usable defensive results. Opus 5.5 can fix everything but the guardrails trigger too easily.

The Fable ban affair was a nightmare for defensive cybersecurity. As far as I’m concerned we’re already in the world of Void Star and Cloudbreaker is here.

if you want to save some $ you can start with abliteration and after few turns switch to normal glm5.3 for example from z.ai subscription or other source. I didn't test it yet with deepseek, but I'm assuming it will will work the same.

those models will follow your request when they already agreed to do this

deepseek tends to quickly assume this is benchmark and even when have web access thinks things like "simulated internet" etc (but waste tokens on thinking if there could be way to cheat)

This is the only AI-safe approach - see the OpenAI agent swarm incident where the swarm engaged in offensive cyber because guardrails were not active for their task and the model had clearly been post-trained on that narrow domain.

Does this make sense? It is the same as when Stable Diffusion tried to not have "people laying down" in their training data in order to block the generation of sex pictures.

Deliberately keeping all models ignorant doesn't make sense. It won't work (whoever breaks the pact has a massive advantage); it won't be enforceable; it will have downstream impacts on things you don't want it to be ignorant about; this kind of regulatory regime invites adding more and more to the "no-no list".

Is it not possible to focus on hardening? And on new legal liabilities for operators who do security attacks?

The difference is that it’s not subtracting an otherwise present part of training, it’s choosing not to continue to push it with RLVR. Models become capable like this when they are specifically tuned to be good at cyber tasks, so without the RLVR (Reinforcement Learning w/ Verifiable Rewards) they never pick up this level of aptitude.

I agree that it’s not obviously sustainable, but it’s better than specifically training these tools to be good at wreaking havoc, and then putting on a shocked pikachu face when they wreak havoc (ahem, Sam Altman).

There is a ton of questions to ask regarding their removal of cybersecurity data.

First, how much “cybersecurity data” is just standard software knowledge that one can derive cyber security exploits from?

Did they also get rid of all references to hacking in general?

Are they implying that all the recent exploits are just things that were already in the data?

For a model it doesn’t seem that far fetched to make the leap from “I have the knowledge of what hacking is” and “I know how computer systems work” to just being able to exploit stuff anyways.

modeless 13 hours ago||
If you're an amazing, top 1% software engineer, and you switch jobs to become a penetration tester, you're not going to be top 1% day one. There's knowledge specific to penetration testing you'll need to research and absorb and practice before you're good.

For the models, it's always day one. They don't learn from experience. Whatever they know after training is all they'll ever know. So if you don't teach them penetration testing in training, they won't know it. Maybe they could theoretically derive everything from first principles, and so could a top 1% software engineer, but that's a very slow and inefficient way to do things.

ByteAtATime 10 hours ago|||
I have essentially no knowledge in this field, but another concern may be that if the model has minimal cybersecurity knowledge, it may also implement insecure systems as a side effect.

You'd be surprised. Cyber offense is a very narrow domain, especially given the extensive mitigations that are being used in modern systems. Leaving it out of post-training tasks unless you're specifically interested in it is the no-brainer approach.

besterman23 13 hours ago|||
Perhaps the gap is just too wide, but to use a more simple analogy. I see this like someone knowing everything about biology, simple mechanics, metallurgy, and human history but never hearing about an axe then assuming that person would never come up with the concept, use case of, or means to create an axe.
croniev 34 minutes ago||
What confuses me about this analogy is that it seems to imply this is a matter of a knowledge-base and logical inferences. But the whole reason why LLMs are so successful is that the logical approach was abandoned in favor of a statistical one (and huge amounts of data, compute, and weights). The argument is precisely, that what is not in the training does not find its way into the probability distribution. To claim that LLMs reason is a very far stretch that I don't feel comfortable to let pass.

Will there be a book of secret knowledge that only the initiated will be allowed to see? And they will all swear an oath to never input it into an AI system?

And then we'd also do that for all kinds of potential terrorism, sex-crimes, political subversion, and evil advocacy?

It would be the "restricted section" like in the Hogwarts library?

zozbot234 13 hours ago||
Post-training is not about "secret knowledge": it's literally about training the model in a RL environment on very specific tasks (including, potentially, cyber exploitation). It's just as compute-intensive as pre-training these days, if not more (given that several checkpoints of the same pre-trained model are being released, showing sizeable gains in real-world capabilities for non-trivial productivity tasks).

Here are the results from the Pac-Man bench. It does pretty well for the price, around Sonnet 5.5.

What's the best bang for the buck ≈$10–20 (per-month/equivalent) subscription for a good enough model these days?
ZiLxxi 20 minutes ago|||
I've tried a few, best so far: DeepSeek API credits.

- OpenCode Go $10: I feel like most of the models are lower quality than directly from the provider. If you ignore my "vibes": the value is very good for e.g. DeepSeek 4.1 Flash (not sure if they're serving 1017 yet), GLM 5.3 Flash, Qwen3.8 Flash and Claude Haiku 5.5.

- Z.AI: Tried the $18/month plan and was disappointed by the usage limits. Even with GLM 5.3 Flash I ran into the 5h limit pretty quickly.

- OpenAI: I tried the $20 plan and $100 plan. $20 ran into 5h limits very quickly with anything other than Luna models. $100 felt like pretty good value for GPT 6.1 Sol, but as others frequently repeat: it's probably heavily subsidized and won't be around forever.

- DeepSeek API credits: I can let a single agent run all day (and not worry about keeping the context small) and am usually around $1 usage for the day. Flash 4.1 1017 is also a very good model IMO. For the stuff I've used it with it hasn't felt any worse than GPT 6.1 Sol. The benefit of API credits is also that they don't expire at the end of the month (like unused subscription usage).

- I haven't tried any of Anthropic's subs, but my guess is you can get a lot of Claude Haiku 5.5 usage out of the $20 plan which is definitely a good model. I'm just not a huge fan of Anthropic or Claude Code, so I haven't tried it.

I had the lowest plan ($20/month I think) and it literally gave me fifteen, maybe twenty minutes tops, using the cheaper K3-256K variant. Basically enough to fill the context about 1.2x and that was it.

It's a really smart model but way too expensive. The same $20 goes 100x further with Claude. I used it for the initial task planning while the plan didn't expire, then handed off to DeepSeek or Minimax.

Same plan, just asked it to review a repo that Fable has been helping out with (max plan, haven't run out of the hourly or weekly limit once yet, and I use the same sub on multiple projects at once). Kimi didn't even finish the scan, ran out of the 5hr budget in less than 10 minutes. Unusable, unfortunately.

As tribute, I bit the bullet on the $40 plan to test out K3.1 Pro.

Still burning through the 5-hour rate limit way too quickly, though. Output quality seems solid enough, but the value will probably make a lot more sense via API pricing for smaller projects.

My current tier list based on what I’ve been testing:

1. Opus 5.5

2. Astra

3. Argon

4. Kimi K3.1 Pro

(For lightweight/daily driver tasks, Gemini Flash 3.8, DeepSeek Flash, and Luna are still up there as favorites.)

egeozcan 1 hour ago||
In my experience, the difference between your 1 & 2, and your 2 & 3 are huge, and I don't find Argon to be usable for any big tasks because it really does a big mess every now and then (which Astra also does but much less frequently and not in a "I just implemented something else with unusable code" way), and Placing Kimi after it seems like a very low evaluation.

If the scores on Artificial Analysis really do mean that this model is better than GPT-6 Astra and Fable 5.1, that means that China is more like 6 weeks behind the US in frontier capabilities rather than 6 months. Which means that the US lead is all but gone.

> Which means that the US lead is all but gone.

You can see in this discussions the goalposts being actively moved to desperately create a notion that the lead is still there.

You even see people in this thread referring to imaginary wonder models that they expect US companies to have under development that are supposedly leaps and bounds more impressive, albeit the only reference there is to their existence is the commenters hopes and dreams.

I think people need to realize that there is no longer a cutting edge company that is expected to dominate, and among the multitude of AI companies in the field competition is so tight that no one would even be surprised if tomorrow some other company far away from the US was able to crank out the top performing model, or something like a small local model that outperforms mid/high tier frontier models. The local model alone would be a death sentence to US companies, who are still burning through 10x their revenue.

Why would they not release those models, since it would help them become profitable and beat the competition becoming the one company rule them all? Oh yeah, they are so dangerous. Well Anthropic revenue comes from only few big corporate customers, so just make them Golden Partners etc. and give them access to super-models. I doubt Google and Meta wants to crack web security.

culi 9 hours ago||
Perhaps you missed this part:

> Open-weight principles. These evaluations frame our open-weight release decision. First, we aim not to release open weights that would extend the absolute frontier of cyber capability. K3.1 Pro's offensive cyber capability is, by design, below what our pipeline can produce, and remains behind that of frontier proprietary models. Second, we intend to progressively raise the cyber capability available in open weights. We believe making K3.1 Pro available in a non-discriminatory way benefits people who need dual-use capabilities for defensive purposes. When a capable model is open and runs on infrastructure its users control, many more teams gain the means to audit the code they maintain — including legacy systems that rarely receive dedicated security reviews. We believe that letting this capability diffuse gradually — rather than concentrating it in a few proprietary systems — ultimately makes all software more secure.

I don't think Chinese labs are behind at all. I think the tell is that they keep releasing models 2 weeks after new American proprietary models that match or beat them. Suggesting they're sitting on much higher capabilities and releasing just enough to undercut

Artificial Analysis index results are up, since multiple people are asking: https://artificialanalysis.ai/models/kimi-k3-1-pro

> When evaluating the Intelligence Index, it generated 150M tokens, which is very verbose in comparison to the median of 87M.

This is 100M fewer than Opus 5.5, 40M fewer than Fable 5.1, and about a third of Sonnet 5.5. In the top-6, it's 3rd, beaten by Muse Wonder at 140M and Astra at, impressively, just 60M.

jwolfe 13 hours ago|||
That's versus Opus 5.5 max effort, no? Opus high has the closest cost and intelligence characteristics and generates far fewer output tokens per task than the one Kimi 3.1 Pro effort level we have data for.
thepasch 12 hours ago|||
Yes, max effort is what the displayed-by-default score on the index is measured by. At xhigh, Opus 5.5 outputs 100M tokens, but remains only 1 point ahead of K3.1 rather than 5. And Sonnet at xhigh outputs 110M tokens and trails K3.1 by 3 points rather than leading by 3, at the same price point per mtok.

Opus 5.5 high trails K3.1 by 1 point, but outputs only 53M tokens, so it indeed comes out cheaper per-task. I think it's still remarkable that this is effectively an open model that matches the frontier for the first time in a long time, pretty much since DeepSeek R1.

So their base price is 1/5th of Opus 5.5 per token, but if you want "highspeed" it's 2x that and then I guess it generates 2x the number of tokens as well?

That might suggest that Opus is competitively priced after all.

In an agentic pipeline, the output text is 2-5% of the total tokens used, so verbosity is a nonissue costwise. Although, higher verbosity could cause input to balloon faster and potentially cost more, but that would be captured by the cost-per-task metric.

But as noted by other replies, it's still lower than Opus/Sonnet.
