A small number of samples can poison LLMs of any size Anthropic research on data-poisoning attacks in large language models

It’s been 5,000 years since I’ve thought about LLMs, which is where my research originally started, but this paper from the folks at @anthropic.com showing that a small, fixed number of documents is enough to poison any size LLM is really powering my brain on again www.anthropic.com/research/sma...

This is what I logged on to see

People wearing union shirts stand outside a red carpet at the entrance of an event as people walk in.

People wearing union shirts and stickers smile and hand out ProPublica Guild buttons.

Five people sit at a table for an event wearing stickers and buttons supporting the ProPublica Guild.

Jeffrey Epstein Email Trove Reveals Ghislaine Maxwell’s Secrets A cache of 18,000 messages obtained by Bloomberg News reveals Maxwell’s deep ties and involvement with the disgraced financier and sex offender.

NEW: We got access to Jeffrey Epstein’s personal Yahoo inbox — more than 18,000 emails.

It shows Epstein’s world in his own words: an unfiltered look at how his operation worked, who enabled it, and how Ghislaine Maxwell stayed at the center of it all.

How We Tracked Workforce Reductions at Federal Health Agencies When the Trump administration refused to reveal how many workers had left federal health agencies, ProPublica turned to a federal employee directory to quantify the impact. Here’s how we did it.

NEW: More than ‎20,500 workers have left or been pushed out of federal health agencies, a ProPublica analysis found.

Staffers say the cuts will leave their agencies less equipped to conduct studies, perform inspections and combat deadly outbreaks.

In March, the Trump administration announced a massive purge of workers at the nation's health agencies. We asked them how many workers were laid off, pushed out or left, and the admin refused to give us numbers. So we conducted our own analysis, a thread...

We took a collective lunch break today to protest @propublica.org management’s continued use of a flawed performance management system.

Just this morning, a member of our Bargaining Committee was fired as a result of this system.

I love working at ProPublica. I would love it more if it could guarantee us just cause protections. Go union.

Reporting this story was mind boggling 😵‍💫 glad to see it make an impact!

Miscarriage Is Increasingly Dangerous for Women in Texas, Our Analysis Shows. Here’s How We Did It. Using seven years of hospital discharge data, we found that the number of blood transfusions during emergency room visits for first-trimester miscarriage shot up by 54% since Texas banned abortion.

Here's how we did this analysis: www.propublica.org/article/texa...

The latest in our series:

Three of my colleagues are being placed on PIPs today, and they will go into those meetings without union representation. We're not shutting up about this — having stewards in disciplinary meetings is a basic union right, and @propublica.org management should do the right thing.

:(

Really disappointed in @propublica.org management for this decision, which is out of step with both industry standards and ProPublica’s mission of accountability.

:’(

… yeah :/

Congratulations to @propublica.org, winner of the Worth Bingham Prize for Investigative Journalism for “Life of the Mother,” a landmark series that showed how state abortion bans in the U.S. have led to preventable deaths and has spurred important reforms.

5/ We will continue to fight for steward representation for our colleagues and call on management to change its position on this vital issue.

4/ Blocking stewards from these meetings is out of step with our industry and the principles of fairness and accountability the newsroom claims to uphold.

3/ Stewards are a critical part of a fair and transparent disciplinary process. They serve as witnesses, note-takers and advocates for our colleagues.

2/ Two of our unit members were just informed that they will be placed on Performance Improvement Plans (PIPs) in meetings next week, the first step in a disciplinary process that often leads to termination at ProPublica. Management said stewards will not be permitted in those meetings.

Hey this is extremely not cool, just in case you didn’t know.

A chart showing sepsis rates in second-trimester pregnancy loss hospitalizations in Texas between 2017 and 2023. After the state banned abortion, rates increased by 29% in Dallas and 63% in Houston.

After Texas banned abortion, the rates of sepsis in 2nd-trimester pregnancy loss hospitalizations shot up by more than 50%, @sophiechou.bsky.social and I found.

But that jump wasn't equal across the state; women in Houston fared far worse than those in Dallas:
