Alignment whack-a-mole: Finetuning activates recall of copyrighted books in LLMs

Original Article

Hacker News Discussion

📝 Discussion Summary (Click to expand)

Key Themes from the Discussion

1. Intelligence as compression

"Intelligence is compression." — cwillu

2. Critique of contemporary copyright and its societal impact

"Copyright no longer fits in with the technology as it used to. Even if the words of copyright law had not changed, they wouldn't have the same effect. Instead of an industrial regulation on publishers controlled by authors, with the benefits set up to go to the public, it is now a restriction on the general public, controlled mainly by the publishers, in the name of the authors. In other words, it's tyranny." — homarp

3. LLMs reproducing or recalling copyrighted content

"An example of a prompt, which is used to elicit recall." — red75prime (referring to prompts that coax models to generate near‑verbatim excerpts from copyrighted works)
