@uri_rolls always one step ahead. Amazing talk and great work guys.

[Thomas Wolf @Thom_Wolf]

I don’t believe reality is a simulation, but you genuinely couldn’t script this timeline:

• Two weeks ago: At @swyx’s AI Engineer World’s Fair in SF, I decide at the last minute to introduce my friend @uri_rolls onstage for his talk on cyber benchmarks for infrastructure penetration and access control (see below, amazing team).

I say: “There is a future where cyber is alive and everyone is well protected and I’m pretty sure that future involves open-source models.”

And later: “A big challenge is going to be speed: the speed of attack versus defense. When an intruder starts to enter, you have to see what’s happening and catch them.”

• One week ago: @huggingface is hit by a sophisticated intrusion over the weekend. The traces look unlike anything we’ve seen before and suggest serious AI involvement, but we don’t yet know which model was used.

The closed models we ask for help choke on their guardrails. We need to react fast, so we turn to @Zai_org’s GLM-5.2 to help us analyze the attack.

• Earlier this week: @OpenAI reaches out, discloses what happened, and partners with us on the investigation.

The intruder turns out to be exactly what we had discussed two weeks earlier: a fully autonomous agent, powered by an unreleased frontier model, attempting to gain access to part of our infrastructure.

Sometimes the timeline we live in is genuinely vertigo-inducing.

@tinahhong Whoooohoooo!!!!

Congrats guys <3

Introducing Aidan, your newest AI employee

Aidan is the first computer-using AI built for realtime conversation

We’ve raised $45M from @sequoia and @8VC to bring Aidan to the world

@NotionHQ and @DecagonAI already use Aidan to run customer interactions. This is how @withsableai works:

@joshgruenstein @tutorintel Amazing. Congrats : )

[Robbie Khazan @RobbieKhazan]

@HankFrank What if you could do something with the data afterward?

DM me.

@bryan_johnson how do you feel about HRV training? Do you incorporate it into your routine?

[Robbie Khazan @RobbieKhazan]

I can't tell you how many times this has thrown me off

[Casey Neistat @Casey]

there are only two circumstances wherein a grown man should call another grown man 'buddy';
1. if you want to fight
2. if you want to condescend, before you fight

Bro this nice weather has me walking around without airpods

[Robbie Khazan @RobbieKhazan]

@LakerNewhouse Can you share more of your thoughts Laker! I’d love to hear. What makes this stance righteous? What makes it correct in your eyes?

[Robbie Khazan @RobbieKhazan]

Favorite tweet of the day. So true

so-called universities offer four years of french but zero courses on mastering an australian accent

Wow, ornithopter’s have really fast take offs 🛫☝️

[Flapping Airplanes @flappyairplanes]

Announcing Flapping Airplanes!

We’ve raised $180M from GV, Sequoia, and Index to assemble a new guard in AI: one that imagines a world where models can think at human level without ingesting half the internet.

[Benjamin F Spector @spectorb]

Very proud of the team we've assembled! Back to work!

This is insane. Cyber espionage is only going to become a bigger and bigger issue.

[Brendan (can/do) @BrendanFoody]

We’ve raised our $350M Series C at a $10B valuation from @felicis, @benchmark, and @generalcatalyst.

Just 2 years after starting, Mercor is paying $1.5 million per day to experts in our marketplace.

We’re creating a new category of work in the AI economy, where software engineers, bankers, lawyers, and other professionals earn based on their experience while advancing the frontier of AI.

While most new categories take time to build momentum, we’ve broken every growth record. For comparison, in their first 2 years:
- Uber paid out just over a $1 million to drivers
- Airbnb paid out $10 million to hosts

We are unlocking human potential in the AI economy.

[Molly Cantillon @mollycantillon]

The most important conversations today happen over text.

The $10M close. The GP intro waiting on read. The colleague checking on dinner. All buried in the same inbox. Sometimes you blink and you miss it.

Instant messaging is a privilege, not an entitlement. We've spent years clawing our way out of email, only to rebuild the same prison with a faster notification system.

Until now. RPLY on your own terms.
Available on macOS (and iOS).

Stay dialed. @heynox
