Introducing Claude Fable 5: a Mythos-class model that we’ve made safe for general use.

Its capabilities exceed those of any model we’ve ever made generally available.

[Shann³ @shannholmberg]

what is agent looping

for the last two years we prompted agents one task at a time. that is starting to change

instead of asking an agent to build the landing page and then driving every step yourself, you set up a loop that handles discovery, planning, the work, checking, and iterating until the goal is met

looping is a setup you build. almost any agent harness can run it, it just depends on how you wire it up

at its simplest, looping is one agent working on itself:

> researches
> drafts
> checks the draft against a goal
> fixes what is weak
> runs that cycle again until the work clears the requirements

you are not prompting each step anymore. the agent repeats the cycle for you

the bigger version is a fleet looping. you give an orchestrator agent a goal, it breaks the goal into pieces, hands each piece to a specialist agent, and those specialists hand smaller jobs to their own subagents

the whole tree keeps looping through discovery, planning, execution, and verification until the goal is met

one agent looping is like a person redoing their own draft. a fleet looping is a whole team running a project end-to-end

you create a goal, and the system runs the loop until it finishes within the reqs you set

open and closed looping:

OPEN LOOPING is exploratory. it still has conditions and a goal, but you give the agent or the fleet a wide space to move in. it can try different paths, discover things, build something you did not fully spec out

this is the exciting end, it is what Peter and others are doing, and tbh it is where I want to spend more time

the catch is cost, an open loop with real room to explore burns an insane amount of tokens. for the 90 percent of people without an unlimited budget it is not runnable yet, and pointed at projects with a loose standard it turns into a slop machine

CLOSED LOOPING is bounded. a human designs the end-to-end path first:

> clear goal
> defined steps
> an eval at each step
> a point where it stops or hands back to you (and feeds back performance data)

the agents still loop, but inside framework you built. it gets better every run because each pass feeds the next, and it runs on a normal budget because the path is tight.

for most marketing work, closed is the one that pays off today.

> the orchestrator owns the goal
> the specialists own the steps
> the subagents do the narrow work
> an eval gate make sure its not slop

6 months ago, I moved to San Francisco.
It’s the best place in the world to build, and one of the worst places to stay human. My unfiltered take:

1. SF is both overhyped and underrated

The overhyped part: there are a lot of people with incredible resumes who are deeply unimpressive in real life. They were at the right company, at the right time, in the right market, and got carried by the wave. They made money, got comfortable, and now spend their time “exploring opportunities” over coffee, wasting your time.
The underrated part: the top 1% here is insane. But almost impossible to get. Hiring in SF feels like being a guy on a dating app: everyone you want is out of your league, and everyone in your league wants someone out of theirs. The best people have unmatchable packages, endless options, and are optimizing for maximum impact: labs, frontier companies, or startups raising $100M pre-seed rounds.
If you raised $10M from Tier 1 investors, you’re not hot shit here. You’re a B-player. It’s humbling.

2. There are fewer mission-driven people than I expected

Especially on the application layer. A lot of people are in “secure the bag before it’s too late” mode. And honestly, it gives me the ick.
The real religious builders I’ve met are often in labs, hardware, biotech, deeptech, defense — places where the work is hard enough that you can’t fake obsession.

3. The status game favors builders

This is what SF does better than anywhere else. It rewards obsession. It rewards weirdness. It rewards people who make building their entire personality. Europe punishes that. SF gives it status. If you’ve felt like an outsider your whole life because you care too much, work too much, think too radically, or refuse to be chill about things that matter, this city will make you feel less insane.

4. The market liquidity is absurd

Even if you don’t build a billion-dollar company, if you manage to build a strong product with a great team, someone smart might still acquire you for $ 100M. Yeah I know, it’s not your dream outcome as a founder, but on the days you feel desperate, it helps to keep going.

5. SF does not care about the meaning crisis that’s coming

Anyone paying attention here can feel that something massive is happening with AI. But I’m shocked by how little people talk about the meaning crisis coming next. Everyone wants to talk about AI liberating humanity. Almost no one wants to talk about what happens when work — the thing that gives most people identity, structure, dignity, status, and purpose — starts disappearing. The vacuum will not be peaceful. People are underestimating the chaos that comes from humans suddenly having no idea why they matter. And I really feel like no one cares.

6. Personally, I’ve never been more unhappy

I moved to SF and entered the matrix. I’ve always been intense. I’ve always worked crazy hours. But here, I lost the last parts of myself that were not about building.
I don’t go to events. Most networking events feel like theater for people pretending to be important. The only events worth going to are small, curated dinners with people who are actually alive. I’ve made 0 real friends. I don’t do well with transactionality. I don’t do well with people constantly performing greatness. I don’t do well with rooms where everyone is optimizing and no one is being honest.

So yes, SF is lonely, transactional, delusional, addictive, inspiring, boring, extraordinary, and completely insane.
But it is still the only place to be right now if you’re a founder trying to build the next wave of humanity.

And for now, that’s enough.

Powered by Claude Opus 4.7, our most capable vision model. Available in research preview on the Pro, Max, Team, and Enterprise plans, rolling out throughout the day.

[Claude @claudeai]

Introducing Claude Opus 4.7, our most capable Opus model yet.

It handles long-running tasks with more rigor, follows instructions more precisely, and verifies its own outputs before reporting back.

You can hand off your hardest work with less supervision.

[Codie Sanchez @Codie_Sanchez]

My no. 1 piece of advice as we enter the AI age:

Stop looking for the career. Go do something absolutely unhinged... string together experiences that have never been strung together before.

[Nathan @natedotdev_]

What we've been waiting for!

[Claude @claudeai]

Introducing Claude Managed Agents: everything you need to build and deploy agents at scale.

It pairs an agent harness tuned for performance with production infrastructure, so you can go from prototype to launch in days.

Now in public beta on the Claude Platform.

[Nathan @natedotdev_]

Couldn't agree more. My team and I are doing exactly this.

[Andrew Yeung @andruyeung]

There’s an emerging wave of solo entrepreneurs who are building $100k - $1m software businesses.

No VC raised, completely bootstrapped, often starting on the side while they’re still employed.

The old path to building consumer businesses used to be to identify demand first by creating a series of landing pages and ad copy - before building the product.

But if creating software is as easy as making landing pages - and you no longer need to raise venture capital to hire a group of engineers - why not just build a series of products instead?

This is the new era of entrepreneurship

[Nathan @natedotdev_]

Crazy work by Pika. Excited to give this one a try.

[Pika @pika_labs]

Conversations tend to go better with a face and a voice. That’s why we’re thrilled to release the beta version of the first video chat skill for ANY agent, powered by our new real-time model, PikaStream1.0.

The skill preserves memory and personality, and enables real-time adaptability. And if you use it with your Pika AI Self, they’ll be able to execute agentic tasks during the call 💅

[shirish @shiri_shh]

generalists are about to win big

If you understand a little of tech, business, and people, and can connect everything fast.

you're sitting on a goldmine right now.

[Nathan @natedotdev_]

@pika_labs Awesome! Will give this a try
