An update for Sonnet 4.5, released last week: it scored 60.2% on my final exam (with extended thinking on, 54.4% without it). That's a big step up (~20 percentage points) from Opus 4.1's scores, and puts Sonnet 4.5 close to, if slightly behind, other lead models. On a human curve, that's ~ an A-/B+
For my latest round of informal tests of large language models, I looked at how good different models are at taking a law school exam—and also whether they are capable of grading exam answers in a consistent and reasonably accurate way. 🧵

One other note: across the five exam answers and dozens of answer evaluations generated here, I did not notice a single hallucination. This test wasn't designed to measure hallucination rates, but it's consistent with the general sense that they have dropped significantly

No, Generative AI Didn’t Just Kill the Attorney-Client Privilege
Opinion: Georgetown Law professor Jonah Perlin says using third-party technology doesn't categorically waive the attorney-client privilege.

Judge Alsup has the first true opinion on fair use for generative AI in Bartz v. Anthropic. He holds that AI training is fair use, and so is buying books to scan them, but that downloading pirated copies of books for an internal training-data database is not fair use. 🧵
🚨BREAKING: Federal judge concludes that using copyrighted works to train generative A.I. is transformative and ultimately a fair use. (Nevertheless, Anthropic can’t beat the lawsuit because it pirated books for another purpose too.) First of kind ruling. www.documentcloud.org/documents/25...

I think this is one of the more common mistakes I see with people trying AI—the idea that if you go to a free chatbot, quickly run a question by it, and it does a bad job, then you've learned that AI cannot do a good job on that question.

A good thread on a big new generative AI / IP lawsuit—Disney and Universal vs. Midjourney
Personally, if I had a machine that egregiously and blatantly violated copyright, I wouldn't have a public "explore page," because the copyright holders might publish 18 pages of examples of me violating their copyright. Suit also includes tons of Reddit guides to doing so too. Oof!

generations! [prompt in comment]” in the r/Midjourney Subreddit, along with the prompts
that were used and the tag “Prompt-Sharing:”17
180. Additionally, in an article on the popular website Medium titled “Recreating
Classic Disney 1930s Style Animation with Midjourney AI,” user InstantAI provided
sample prompts for Midjourney to generate copies of Disney’s Copyrighted Works,
including Snow White. In response to one of these prompts, Midjourney accessed the data
about Disney’s Copyrighted Works that is stored by the Image Service and then generated
the following image which infringes Disney’s Snow White character:](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:qc6xzgctorfsm35w6i3vdebx/bafkreihp5no4x2iy55hasu6o7hxh6qldl4fzfcoo7pjmu4wmw7xsinig7e@jpeg)

This is one of my favorite books to recommend to students (I actually have two copies). One of my teaching aspirations is to someday have a seminar read this alongside @nbagley.bsky.social’s Procedure Fetish and Kagan’s Adversarial Legalism.

People often treat AI-generated legal texts as an issue of legal ethics (e.g., hallucinated citations) or industry economics (will AI replace associates?). But as legal institutions start receiving, processing, and using generative AI, it's going to affect all of us 🧵
