I've been a software engineer for more than a decade. Most of the public doesn't understand the scale here, which shows how implausible it is to effectively monitor what happens in these huge eval/training runs.
I fired up my @CommunityNotes AI writer again. It hasn't made it into the program yet, but I made its activity public for anyone to watch. I'll be adding benchmarking data as I compare how different LLMs do at flagging political misinfo. Check it out here: alexmahadevan.github.io/cn-b…
It is pretty wild. I am seeing around 17% of notes from the bots going public, compared to like 7% for humans.

Seeing more and more great AI notes lately
Law enforcement uses ‘reasonable suspicion’ to make arrests, as protected under the Fourth Amendment to the U.S. Constitution. The Supreme Court has already vindicated us on this position.
A person’s immigration status makes them a target for enforcement, not their skin color, race or ethnicity.

Readers added context they thought people might want to know
The Fourth Amendment requires probable cause for arrests; reasonable suspicion suffices only for brief investigatory stops, not full arrests. law.cornell.edu/wex/probable_c… law.cornell.edu/wex/fourth_ame…

check out my new AI quiz and try so spot which TALKING videos are AI or not nytimes.com/interactive/2025…
I’ve always said @CommunityNotes is great at flagging AI slop, especially if it’s not political. If Meta’s Community Notes can’t get a stable note attached to this slam dunk post then I’d say the system is an absolute fail.
My God. There are now TWENTY @CommunityNotes ratings files.

New: Here's a chart of the top conservative / progressive accounts on X. See that small blue dot at the top? That's @Acyn. His fast-cut clips of political combat get hundreds of millions more views than major news sources - and basically no one knows who he is. So I profiled him.

As TikTok follows X and Meta into a "community notes"-style form of fact-checking, @Poynter's @itsren talks with @AlexMahadevan about what could go right or wrong. poynter.org/commentary/2025/…

I actually wondered when this would happen after Sora launched and you could see what people were making
Such a giant baby. LIV Golf incarnate. Could not be happier today.

Nearly half of Americans say they don’t want news from generative artificial intelligence, according to a wide-ranging study from @Poynter and the University of Minnesota on audience AI sentiment.

hell yeah
Replying to @redvik124
@redvik124 Here are some X accounts known for neutral political analysis on world politics: @Natesilver538 (data-driven forecasts), @FiveThirtyEight (empirical insights), @politifact (fact-checking), @CookPolitical (election analysis), @amyewalter (balanced commentary), and @factchecknet (nonpartisan verification). Neutrality may vary by perception, but these focus on facts and data.

New: @factchecknet condemns raid on CRTA, home of Istinomer fact-checkers, in Serbia. Serbian authorities premised the raid on unproven claims from Trump, Musk and other US officials about USAID program corruption. poynter.org/news-release/202…
