If they didn't want us to use other people's ideas without permission then why did they use other people's ideas without permission to make the ideal tool for using other people's ideas with permission?

These days? This is how spotify was found. Its same playbook. Steal everything and then do regulatory capture.

Comment by phil-martin 1 day ago

I don’t think it’s about what Anthropic does or doesn’t want us to use their tools for. They are in the business of selling compute via AI, the more people that use it the better.

This is about stopping future issues (real or perceived) that could lead to legislation curtailing usage of their tools.

Comment by throwa356262 1 day ago

These guys are no fun at all.

Is this really the same cowboys that recklessly broke into others networks and instead of apologising proudly told the world how they did it?

Every 6 months Anthropic publishes a report telling us how closer they have gotten us to extinction as if human life was just a game, yet now they draw the line at computer game modding??

Is this.. The right approach? Who decides what gets to be reverse engineered and what doesn't? I don't have a solution to offer, but I bristle at the idea of one indistry deciding which other industries suffer the negative externalities of their product, while others they decide are spared.

currently running 2x DGX Sparks and never thought to use a commercial model again

Comment by cyberpunk 1 day ago

Curious about your setup if you don’t mind elaborating a bit for us? What models are you using and how do you find they compare? The 128gb model costs less than one months salary for a medium level engineer here, they look quite attractive.

Comment by anakaine 1 day ago

A month and a half salary after tax here. That is still particularly expensive, and besides its sinking money into a steeply depreciating asset.

Comment by jareklupinski 1 day ago

i've been running DeepSeekV4 flash but looking at the other models being suggested around, best part is switching to test has 0 cost :)

i felt like commercials LLMs were "good enough" for my needs about 2-3 generations ago, so this clicked into my work/life needs perfectly

i got them right before they went up in price, but honestly, for the ability to know that i wont have my thinking "questioned"... priceless

Comment by spwa4 1 day ago

Best model on 2xSpark currently is GLM 5.3 flash ... but really does require 2x Spark. 25 to 60 tok/s with MTP.

Comment by anakaine 1 day ago

2x Spark? As in two DGX Spark machines? That is obscenely expensive.

Comment by cyberpunk 1 day ago

Is it? How much would it cost to hire a person to do the same work two of these can do?

Comment by hamdouni 22 hours ago

Maybe fair to compare to using AI subscription ~20$/m (not Anthropic neither Openai)

Comment by spwa4 22 hours ago

Especially now with OpenAI constantly changing (and always reducing) what the subscription can do ... At least it will keep working.

Right now I need 4 subscriptions to do what 1 used to do. And they're tightening it further, without announcing:

https://news.ycombinator.com/item?id=50320588

(technically it isn't even legal, since changing what people get after they've agreed to the sale is obviously highly illegal)

Not that they've ever actually announced how much a subscription buys you. In fact the token use for a task on the API is also not consistent, so even on the API you don't know. And then there's Sam Altman in interviews, where he says what he wants to do: you submit a prompt, ChatGPT sends you a price and just charges it.

Comment by drnick1 1 day ago

> whoever owns the hardware

Yes and this is why self-hosting is more important than ever. The issue with LLMs is the cost of hardware if you want something close to the frontier. But there is no excuse not to host your own files, email, media center, etc.

Comment by multjoy 1 day ago

Email is, given the issues with connectivity, something you can justifiably make someone else's problem.

There's no reason not to have your own domain though. I've been using Migadu and the amount of flexibility that gives you is ridiculous. The only downside is the lack of push notifications, but if your email is so important that you can't wait for a refresh then I can't help.

Comment by 1 day ago

Comment by jareklupinski 1 day ago

same as self-hosting email/webservers though, you dont need world-class hardware for personal projects. frontier models may be more capable but a smaller model can just as easily work through a project you break down for it

The money we are talking about.. A lot of these rights holders have more than enough cash on hand to bring a suite and potentially destroy Anthropic/OpenAI with the right case.

Comment by cortesoft 14 hours ago

Who? Netflix and Disney are the largest media rights holders, and they have market caps of ~$250 billion and ~$190 billion, respectively. OpenAI and Anthropic are both privately held, but currently have valuations of somewhere in the $1-2 trillion range.

That is not a fair fight.

Comment by greycol 13 hours ago

While a good rule of thumb for the US court system is that someone with more money can screw over a smaller party. That's only up until a point. The most expensive lawsuit in history by legal fees was (adjusted for inflation) $1.15 billion. That was the 1998 Tobacco masters settlement (involving years of litigation by law firms across 46 states). So any award in the billions makes a case arguably justifiable (even more so when the highest litigation cost cases are often that expensive because the litigation fee includes a percentage of winnings).

Companies like autodesk with a ttm revenue of $7.8 billion would probably have fiscally compelling cases (if not legally compelling) to pursue if reverse engineered tools cut into their revenue. That's without getting into class action cases.

Exactly.

Adobe had a FY2025 operating income of 8.7b on 23.77bn revenue. They employ over 33k people..

So Adobe alone has the money for a law suite that defends themselves from an existential threat, but I would imagine a class action.. It is, IMHO, just a matter of time before these companies put it together and take their shot.

They are also probably intentionally trying to create differentiation between their models and open models to strengthen the regulatory capture case of having the government ban open model use.

Comment by doginasuit 1 day ago

I can see your point, but on the other hand it seems like the only alternatives are a blanket ban on reverse engineering or a blanket allowance. I probably don't have to make the case for the value of reverse engineering here, so the question is to what degree it can be abused and if they have the responsibility to stop it. I would argue companies do have an obligation to consider and mitigate abuse of their product, especially frontier technologies. Probably the best outcome will be some kind of balance of judgment by the company.

Comment by ada-h00k 1 day ago

A blanked allowance would be the answer. Claude is just a tool, after all. Neither Ghidra nor IDA tells me what I'm allowed to decompile and what I'm not. If someone then uses it to create something whose distribution would constitute a copyright infringement, that is the responsibility of the person who did so, not the software manufacturer.

Comment by ben_w 1 day ago

Several AI companies are getting sued for what their products allow users to do, as was Google for what YouTube allowed its users to do.

YouTube is probably an instructive example here: they can refuse to host certain content on their servers, and this is Anthropic refusing to have the AI on their servers perform certain tasks.

Comment by plaguuuuuu 1 day ago

It's the wrong approach, because the public demand to reverse engineer games (a pretty benign activity, for humans at least not corporations) is massive and a new subset of hackers who will release public jailbreaks that could be used for hacking which is more of a grey area

Ultimately, the person offering the service gets to decide what the service is.

Comment by Buttons840 1 day ago

We're already knocking on the door of just clean-room recreating any game or experience in one shot. In such an environment, who really cares about reverse engineering old games?

I mean, from game company perspective, will they really care about their old games getting reverse engineered when their next big title can be clean-room recreated by anyone with the skill to write a sentence? Maybe creating a game similar to the next big release will be something that the AIs refuse to do next? Interesting times.

As an aspiring game developer myself, I guess reducing the accessibility of old games benefits me (but I don't like it)--and hey, if you can't get that old game to run, maybe we can vibe code for a weekend and make a new game that captures the same feeling.

Comment by willtemperley 1 day ago

Tetris copyright for example is still heavily policed.

I think however if games continue to be killed there should be a legal route towards the community taking ownership in whatever way is necessary.

Laws, ideally.

Comment by altmanaltman 1 day ago

> Who decides what gets to be reverse engineered and what doesn't?

The service provider decides the terms and conditions, as long as they comply with the law. For example, Google decides whether pirated movies can be hosted on its cloud service, because it provides the cloud service. It's pretty clear.

In a pure capitalist system, competitors would emerge if the repressed service were genuinely in high demand and lawful. If it was not, then well, that's just how we regulate the world but this cannot be considered a case of one industry deciding the fate of another.

Comment by SladeReaper 1 day ago

Honestly the collateral worries me more than the game policy itself. The Tom's Hardware piece mentions users saying generic reverse-engineering tasks get blocked too, and a classifier looking at disassembly can't easily tell a commercial game from your own firmware, a binary you're patching for interop, or a CTF challenge. If a filter is going to draw that line, I'd rather it were documented than discovered one refusal at a time.

Comment by newprint 1 day ago

Game REs & crackers are probably the most persistent personality types you can find in software world. They are also one of the most technically sophisticated software engineers around. I expect we will see a new AI system pop-up soon, made by RE, specifically trained to RE games/software, thanks to this ban. Pandora box is open.

Comment by mirashii 1 day ago

They really didn’t though. They put it in a client side modification to the system prompt. You can just rip it out with a proxy or a small local modification to your client, which Claude will be happy to do for you. They took a token step so that people would write these headlines in the hope it would stave off more negative attention in the video game world without actually doing anything meaningful.

Comment by cedws 20 hours ago

IIRC Claude has some kind of mechanism where even though the system prompt is sent from the client, if it’s modified it can trip tamper checks and result in a ban.

Comment by elevation 1 day ago

I wanted to reverse engineer a win-xp era game with boring music and make it play my own selections--inherently a fair-use activity. The game was somewhat obfuscated, so while I've used ghidra successfully at work, I wasn't able to work out how the game's system design even after a saturday of poking at it.

Claude has already refused to perform incredibly not-security-relevant tasks, so I'm guessing it will simply not help with this now either. Today, I am, for the first time, looking into my own LLM hardware.

Comment by torben-friis 1 day ago

I think that, excepting part of the HN crowd and linkedin, literally the only positive comments I've heard about AI have been related to game mods.

I'm saying this as a completely orthogonal conversation to regularisation, ethics, etc. It's just amazing to see how little value these companies place in the general public's perception of them.

Can you think of any other companies selling to the mass marker that care so little about it?

Comment by BLKNSLVR 1 day ago

I think that they think, not necessarily incorrectly, that their tool is applicable across any and all domains, so restricting a few of these domains is small fry in the overall big picture.

What they may be missing is that the domains in which it it's being used to great success is the pipeline to the expansion of is use into other domains.

Having said that, the potential legal issues of being a reverse engineering tool is a strong legal motivator. But I also doubt that any legal issues as a result of reverse engineering could be fatal to either Anthropic or AI/LLM usage; the tool, being general purpose, will allow for the legal responsibility to be put upon the person using it, especially if it's decided that Anthropic and OpenAI are protected national security assets.

On the contrary, this reads to me as a response to the "we're taking down our game demos because we can't risk AI decomp-cloning attempts" and "oh you released a promising demo for your indie game? Pay me $200 not to make a slop clone of it and release it before you" incidents that have gathered attention outside HN, and it's the average HN commenter that's misinterpreting public perception on this specific topic because the hobbyist classic-game recomps dominate this feed.

The things that normal people will want to use AI for (game mods) will be made illegal or a ToS violation until the only thing allowed is to consume veiled advertisements.

Behind closed doors the elite will use the tech for (biological) weapons and reverse engineering though. Military applications, OK but don’t you dare put Sonic in Super Mario.

Very sad. I'm about 50% in taking the old Red Alert 2 and get to something that would've resembled the original source code.

Given the rumors that the source code has been lost (and the fact that they open sourced the games before Tiberian Sun & Red Alert 2, and the ones after those), I felt like I was using the tokens for 'good'.

We'll see when it actually stops.

This is a good canary of what people were discussing in the past.

Its fortunate that openai or other party did not get to monopolize the Ai coding game and we have a way out in commoditization and open models.

Comment by dualvariable 17 hours ago

Yeah, if they cripple the ability to mod video games, that'll result in a lot of users learning how to use alternative open weight models without all the refusals.

Anthropic really needs to be considering the fact that a lot of those people will be working in IT--and when their bosses start complaining about the checks they're writing to Anthropic, they'll have solid experience with alternative solutions to suggest.

I am busy working on an embarrassingly ambitious game reverse engineering project. (To the point where admitting what it is feels like telling someone you’re working on a perpetual motion machine).

It’s a new tool to reverse engineer games in a specific context, and I’ve been using anthropic models to work on it.

I haven’t seen any increase in safeguards triggering or any negative effects in how quickly agents are able to make progress in this space.

To give an idea of scope it’s about 5000 commits, 500k lines of rust code, 100 Ghidra patches of work so far. Made in around 6 weeks worth of 8-15 agents working continuously.

A very rational choice by Anthropic.

The cost of blocking videogame reverse engineering is trivial. They added three lines to the system prompt to exclude it and probably made a small update to their backend training classifiers. They give up the videogame reverse engineering market, which is a tiny future revenue stream and not worth much financially. In exchange they avoid hundreds of millions, maybe billions, in future copyright lawsuits.

Providing this service has negative expected value. It's better to cede the market to someone else.

Will the lawsuits not come from adobe? From big SaaS companies? From every other major piece of software any Joe will be able to duplicate with a single prompt in a few hours?

This admission is showing that Anthropic believes they might get in hot water for reverse engineering video games. Surely it applies to everything else.

Comment by Rapzid 1 day ago

They are absolutely going to be getting sued by major software IP and copyright holders.

Adobe and other companies have been holding back because they are also using frontier models to keep pace. Suing Anthropic means getting cut off. But now that alternatives are proving themselves..

This, to me, is why Anthropic is rushing their IPO.

I simply can't imagine a company of Adobe's size (employing over 33k people and making 24bn annual revenue) is going to sit on the sidelines while this plays out.

And they are just one company. All faced with a technology that can simply copy all their hard work and investment in product development.

Comment by tristanj 1 day ago

Video game reverse engineering is the biggest and most visible problem in the present moment, it's widely discussed in the media, and there are video game companies known to be very litigious against people who reverse engineering their products (ex: Nintendo). It makes sense to block the biggest problem first.

If future lawsuits come from other industries, then they'll likely add a blanket ban on other forms of reverse engineering.

Comment by avaer 1 day ago

> They give up the videogame reverse engineering market, which is a tiny future revenue stream and not worth much financially

Btw video games are by far the biggest entertainment industry in history.

If the way video games of the future are made is with AI, the logic might be reversed; giving up some lawsuits now, while missing out on large entertainment revenue in the long term.

Comment by tristanj 1 day ago

But that's not at all what Anthropic is doing. Anthropic is not blocking people from creating video games with AI. Using Claude to create new video games is completely valid and unrestricted; they just don't want people to use it for reverse engineering existing ones, as that opens them up to massive legal liability.

Comment by avaer 1 day ago

I agree this is about money and they don't want to be legally liable.

But Minecraft is reverse engineered Infiniminer. Fortnite is reverse engineered PubG. LoL is reverse engineered DotA. This is literally how the industry works.

The next best thing is gonna be some degree of RE of existing stuff -- that's clearly what people want. Anthropic is just trying to placate the old guard, denying users what they want, and ultimately will be on the wrong side of history on this.

That's why I'm saying their move seems extremely short-sighted. They're locked in on the IPO at the cost of the future.

Comment by tristanj 1 day ago

You are confusing game design inspiration with code/asset reverse engineering, which are entirely different things.

Taking inspiration from other games, i.e. implementing similar gameplay loops or mechanics from other games, is completely normal within the industry. Unless copyrighted, it's not illegal. Minecraft taking from Infiniminer, or LoL taking from DotA is industry practice. Claude doesn't prohibit this.

Reverse engineering, i.e. decompiling game binaries to extract source code and copyrighted assets, then generating derivative games using said materials, is grounds for a massive copyright lawsuit. Anthropic doesn't want a part of this. That's why Anthropic is preemptively prohibiting it.
