During pre-release testing, Claude Fable 5.2 and Claude Mythos 5.2 worked on ambitious projects in many different fields. Here are a few.

From a one-paragraph prompt, Fable 5.2 designed three working electronic devices, including this home voice assistant hub.

I’ve learned 100+ lessons after sending 50,000,000+ cold emails.

I wrote them ALL down inside 1 playbook...

(and I’m giving it away, free)

For context...

Most outbound motions fail because people overcomplicate them.

They chase whatever trick is working this month... personalized videos, fancy personalization, subject line tests, etc.

Then the trick stops working, and they're left with nothing.

Meanwhile, the fundamentals that determine whether or not a campaign performs NEVER change.

That said, I learned this the hard way myself.

And along the way building my agency and servicing 120+ b2b companies... I put this resource together.

It has ALL 100+ of the most important lessons I’ve learned for winning at cold email, and gives away the exact process we use to audit, adjust, and scale campaigns.

(for reference, my team sends 8M+ cold emails and books 2,000+ meetings EVERY month for our clients)

Here's what a few of these lessons have done for other b2b companies:

> A precision manufacturer went from 1 positive reply per 1,800 prospects to 1 per 700, just by changing the offer

> A B2B SaaS company selling to libraries got 108 demos and signups in 2 weeks, after we offered a pilot instead of a demo

> A B2B client got 3,513 positive replies off 2.6M cold emails in 14 days

What is inside:

1) Using PCPL as your scoreboard
2) The 4 WHYs every cold email has to answer
3) Segmenting only on data you can actually see
4) Offers that make the next step easy to say yes to
5) Follow-ups that add something new (and when to re-contact instead)
6) The exact rule for when to replace a domain
7) The 5-minute speed-to-lead SLA on positive replies
8) Testing 1 variable at a time, with 1,000+ prospects per variant
9) Why proof that's relevant beats proof that's big

Apple is opening Pages, Numbers and Keynote to AI agents through MCP.

That means agents can edit the document itself, instead of giving you text to copy over.

[Arjav Jain @lifeofarjav]

Tried Fo Friends with a friend (@atishayhyperke) today.

My AI messaged his AI, checked both our calendars, found a time that worked, & booked it after he confirmed.

Pretty cool seeing AI agents coordinate with each other.

Is it a crime to forget my husband’s birthday?

Starting today we are launching -- Fo Friends. A secure way to have your Fo's talk to each other. Do autonomous calendaring, gifting and planning. What this would mean for my husband's forgotten birthday:

* my husband’s Fo pings mine a month in advance,
* if i was dumb, and he didn't live with me, it would also share his address with my Fo
* my Fo picks out a gift
* our Fos coordinate to block our calendars for the upcoming events

A life-saver, since apparently my Fo Type is a hot mess!
Check out your Type and if you are like me invite your friends to be Fo Friends.

[Arjav Jain @lifeofarjav]

Here’s the actual demo of my Fo coordinating with another Fo.

One prompt and Fo confirmed a suggested slot with my friend’s Fo, and booked the meeting with a Google Meet link directly on our calendars

ngl this just keeps getting crazier!!

[Arjav Jain @lifeofarjav]

Google's Genie 4 turns a prompt into a world you can walk around in, in real time.

Type mid-simulation and the scene changes. Ambient sound, music and dialogue are generated too.

Research preview now; AI Ultra subscribers get it soon:

OpenAI published how it watches frontier agents for misalignment: activation probes, a second model reviewing reasoning and tool use, checks at least every 30 minutes on frontier runs.

If you build agents, this is where detection is heading.
