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.

[Alex Mahadevan @AlexMahadevan]

@dylfreed You're killing it on the AI beat, man

[Alex Mahadevan @AlexMahadevan]

I finally made it!!

I demand a correction from WSJ opinion editor Paul Gigot, who dubbed me an “internet ethicist” in his piece today explaining the paper’s new policies on AI. To be clear: I believe in a cool, unethical internet.

[Alex Mahadevan @AlexMahadevan]

@maxwelltani I'd say precedent setting... for the WSJ. Their opinion section's audience is likely far more forgiving of something like this, but I highly doubt any other news org's opinion audience would be.

[Alex Mahadevan @AlexMahadevan]

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: https://t.co/iiPsSlQeM7

[Alex Mahadevan @AlexMahadevan]

It is pretty wild. I am seeing around 17% of notes from the bots going public, compared to like 7% for humans.

[Jay Baxter @jaybaxter]

The average AI community note writers have a much higher “hit rate” (% of proposed notes that become rated helpful and show on X) than the average human.

Now that they’ve proven themselves at a small scale, get ready for more & faster AI notes with this update 🚀

[Jay Baxter @jaybaxter]

This community note brought to you by an AI note writer

Seeing more and more great AI notes lately

Knowing the history of Bob Ross' likeness, and the shit his business partner put his family through after his death, makes the Bob Ross videos on Sora particularly grotesque and revolting

[Alex Cohen @anothercohen]

Bob Ross vibe coding was the AI slop I never knew I needed in my life

[Stuart A. Thompson @stuartathompson]

check out my new AI quiz and try so spot which TALKING videos are AI or not https://t.co/K0r7dFKelU

[Alex Mahadevan @AlexMahadevan]

✅ Not transparent
✅ Can’t catch AI slop

How you gonna copy Birdwatch but without any of the good stuff lol

[Alex Mahadevan @AlexMahadevan]

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.

[Alex Mahadevan @AlexMahadevan]

My God. There are now TWENTY @CommunityNotes ratings files.

[Drew Harwell @drewharwell]

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.

[Medill Local News Initiative @LocalNewsIni]

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. https://t.co/WkRRwznHMG

[Alex Mahadevan @AlexMahadevan]

@jaybaxter Honestly, what if y'all used the bridging algorithm for the For You tab, not just Community Notes

I actually wondered when this would happen after Sora launched and you could see what people were making

[Kylie Robison @kyliebytes]

SCOOP: OpenAI is working on its own X-like social network, according to multiple sources familiar with the matter. While the project is still in early stages, we’re told there’s an internal prototype focused on ChatGPT’s image generation that has a social feed.

Such a giant baby. LIV Golf incarnate. Could not be happier today.

After Tiger won in 2019, Finau joked that he realized it wasn’t gonna be a chatty day when he asked Tiger how his kids were and got a one-word answer: “good.”

My humble opinion is that I think you’re allowed to focus on winning the Masters on Sunday
