If I Own Claude's Outputs, Why Can't I Train My Own Model on Them?

If I own Claude's outputs why can't I train my own model on them?

If I Own Claude's Outputs, Why Can't I Train My Own Model on Them?

Anthropic's support page clarifies that while users own the outputs they generate with Claude, they cannot use those outputs to train their own AI models. The policy prohibits using Claude's outputs to develop competing models or services. This restriction applies to all users, including those on paid plans, and is part of the broader terms of service.

You may not use Outputs to train models that compete with Anthropic.

    > When customers use Claude to generate Outputs that then train competing models, they're essentially using our infrastructure and investment to build direct competitors to our service

    We did so, please do not repeat it at home.

    I have released some of my projects as Open Source, I also have a company with privative software.

    Claude and AI partners have taken all what they could from the Open Source projects without giving credit or respecting the licenses. They have increased the traffic on websites in an absolute disrespectful way increasing the hosting cost in inefficient and ridiculous ways.

    They have taken all the important books and not asked permission from the authors.

    Fair enough. Fair use.

    Of course I would create a competitor software to Claude or any others if I could. Using Claude(and others) of course.

    I am not paying you 200 dollars/month for you to tell me that I could not create code that competes with you. If you try to go to court in Europe with this you will lose.

    It is just the same fair use you proclaim for taking the data from others.

    They stole all the data, and then dont want you to steal it back. Its basically Robin Hood all over again.

    I was not asked for permission when they trained their model on my output.

    Corollary: If you can't use the output to train, then you don't own them.

More from this day
