Very hard to eliminate the possibility of a lot of infringing output

Dominoes start to drop: Uncharted Labs d/b/a Udio settles copyright lawsuit filed by UMG Recordings. Announce new AI music platform to launch in 2026. Here’s the press release below. The settlement does not include Sony and Warner Music Group, 2 other plaintiffs in the lawsuit, which apparently will continue on. UNIVERSAL MUSIC GROUP AND UD…

As predicted, but I think music generation is something of a special case.

This is a screenshot of a conversation with Claude. If you want to read the text, follow the link. It shows Claude resisting a name cloze test, but then backing down.

Claude is showing some resistance to being tested on memorization. claude.ai/share/603385...

How should law schools adapt to generative AI? my new paper, AI Policies for Law Schools, proposes a template policy and explains why we should prepare students for legal practice as it will be, not as it was.

Wispr Flow is amazing, I can't recommend it highly enough, but it can interpret random sounds with something like this: "For more information, visit www.fema.org"

Why can't you copyright an AI-generated image that looks creative? My latest explores the "Skater Beagle" puzzle - how generative AI creates genuinely new works from latent space, not remix, but still lacks the human authorship copyright requires. matthewsag.com/skater-beagl...

This is a guide to drafting law school ai policies.

Photojournalist Bill Biggart died when the second tower collapsed on him on 9/11, but the film he shot that day and his flash card were recovered from the debris and developed, along with his flash card.

You can see his amazing photos of 9/11, the last photos he took while alive, here:

A new NBER working paper by Stella Jia and Abhishek Nagaraj makes some stunning claims about the effects of pirated book corpora on large-language-model (LLM) performance. I have my doubts. matthewsag.com/piracy-proxi... #AI #Copyright #books3

Why is everything about WordPress so ugly and awkward these days?

A Dad Tried To Bully Me Into Giving My Seat To His Kid. Here's What Happened When I Said No. “Oh yeah? That’s your seat?” He reeked of beer and a jagged vein bulged from his left temple. “Why are you so special?”

Invisible disabilities are all around you. www.huffpost.com/entry/dad-bu... "Advocating can be confusing and hard when your disability is invisible. ... People with disabilities, invisible or not, shouldn’t have to explain themselves. Nor should accommodations for them be met at the lowest bar."

Is the EU really the "rights-based" leader in AI regulation?

In "The Illusory Normativity of Rights-Based AI Regulation," Yiyang Mei and I argue that this widely accepted assumption fundamentally misunderstands how EU AI regulation actually works. papers.ssrn.com/sol3/papers....

This is what @United says after holding you on the tarmac for 2 1/2 hours.

Stuck at O’Hare waiting hours for united to let us off the plane. I’m beginning to question my life choices.

I have all discussions of the president muted, so I had to hunt for this

I think everyone on fox news is infringing

Robots can’t be sued for copyright infringement either. But I think we all know that’s not the issue

GenAI has kept me so busy on copyright law issues that I have not done any empirical work for a while. Switching from Stata to python with Claude is a revelation! You still need to do the conceptual work, but its amazing.

It features pieces from @orlylobel.bsky.social, @ariezra.bsky.social, Aleksander Goranin, @matthewsag.bsky.social, Peter K. Yu, @jessicasilbey.bsky.social, @nicholson.bsky.social, and @saragerke.bsky.social!

Also my BMI just shot up! Guess I better get some Ozempic.

Just checked my after visit summary from my health care provider. Was sad to see that I have lost 12 inches in height. Just as well they use infallible humans and not silly hallucinating AI tools.

Is that the difference between blue sky and X?

It's really impressive how quickly journalists are able to digest a 40 page opinion, talk to half a dozen sources about their reactions and get something in print. No LLM is going to replace @knibbs.bsky.social.

Honestly would love to get these two judges on a podcast together to duke it out

quote from judgment: "Meta and its law professor amici, as well as the Matthew Sag article cited above, argue that market dilution does not count under the fourth factor. They argue that harm caused by an LLM’s outputs is only relevant if the outputs are themselves infringing—that is, if the LLM regurgitates copyrighted material (or generates text that is substantially similar to copyrighted material). ... But that can’t be right."

Always nice to be cited followed by "But that can't be right."

As @bb.usefairuse.com said, the vibe is that books from LibGen are radioactive. But see Kadrey v Meta. So lots more will be said on this.

Good law review note question: Can JK Rowling enjoin the distribution of LLama?

No good evidence on memorization in the Meta case according to the judge, but he was focused on the works of the lead plaintiffs. So they just need JK Rowling as a plaintiff?
