Anthropic paid $1.5 billion in compensation to copyright holders for use of their content in training data.

The payment was for illegally downloading copyrighted material, not training. Training was explicitly ruled to be fair use.

reply
Partially correct. The court explicitly ruled that training on pirated data, which is what Anthropic was doing, is not considered fair use.

Training on legally acquired / licensed data is potentially fair use.

reply
It's not potentially, it's settled. At least for now as neither case wanted to move on to appeals
reply
Not at all. The ruling came from a federal district court, and since it was settled early, it was never reviewed by a higher court. It doesn't set a national precedent across the U.S.

And other district courts don't agree on this. The US district court for Delaware recently rejected a fair use defense for the use of copyrighted works to train AI. https://www.reedsmith.com/articles/court-ai-fair-use-thomson...

There are more cases in the pipeline. The massive NYT vs OpenAI is still ongoing. Nothing will be "settled" until this makes its way to the Supreme Court or Congress steps in.

reply
they didn't pay yet, because court challenged settlement as inadequate.

> I doubt the Chinese models operate under similar licensing agreements.

US corps likely pay licenses when afraid to be sued, or have troubles getting that data, otherwise they just take data, which was demonstrated many times. The same apply to Chinese corps, alibaba totally can be sued in US.

reply
China is infamous for weakly enforcing copyright law. Even when it is completely obvious that Chinese labs are training models on pirated data, US copyright holders face a virtually impossible task of proving it in court. Those lawsuits won't go anywhere.
reply
There are tons of lawsuites which resulted in banning Chinese companies from doing business in US, those lawsuits totally have consequences.
reply
They settled with a subset of copyright holders. Guarantee they violated lots of others' rights in the process
reply
They only paid when they got caught. And not to everyone.
reply
But they still paid. I don't see any Chinese labs paying billion dollar infringement settlements.

Chinese labs can freely train on pirated material, which is a structural advantage.

reply
really!? nobody paid me anything for my comments on HN.
reply
The only ones getting paid this time around had registered copyrights (in the US at that.)
reply
Let’s not forget that Anthropic only paid that to settle a class action lawsuit.
reply
That's like saying someone is a big proponent of community law and order, and they donated $1000 to the county sheriff when actually they got caught drunk speeding in a school zone.
reply
A false equivalence. A more correct example is: Anthropic was speeding, got caught by the county sheriff, and paid the fine. Anthropic stopped speeding.

Meanwhile, Chinese labs are speeding in a different county. Everyone knows they are speeding, yet the sheriff won't pull them over, so they just keep doing it.

This lax enforcement gives Chinese labs a structural advantage over American ones.

reply
> Anthropic stopped speeding.

Do you purport to know for a fact that they're no longer training on the data they'd pirated? Because I highly doubt that.

reply
Anthropic deleted the pirated training data as part of the settlement https://www.ropesgray.com/en/insights/alerts/2025/09/anthrop...

Destruction of Materials: In addition to the monetary compensation, Anthropic has agreed to destroy the two libraries that allegedly contain the pirated works, as well as any derivative copies originating from those sources. Anthropic must certify in writing to class counsel that the destruction has been completed and that the allegedly infringing materials are permanently removed from its systems.

The libraries in question were Library Genesis (LibGen) and Pirate Library Mirror (PiLiMi).

If Anthropic is training models on deleted data, I'd be quite impressed.

reply
They used two of my books and I'm still waiting for my cheque here.
reply
After the fact. They did the same thing Youtube, Uber and Airbnb did: Break the law, eventually get caught, cut some deal where they pay a pittance and keep doing the same thing but now with leverage on their side.
reply
Because they got caught

there is much less intellectual property in China so it’s not ‘theft’ (as you can’t put property on information)
