I spent the whole weekend building new security tools for teams. My whole company is really excited about them - they’re even giving you free credits to use them. Please check them out:
We are entering a new dark age of cybersecurity. Devin is here to help.

Introducing the new Devin Security: powered by Claude Mythos and frontier cyber models, plus hundreds of millions of dollars of credits to help teams find, prioritize, and fix urgent vulnerabilities.

I've been working hard overnight to patch vulns. Shared some of my work here so you can benefit from it!
We’ve open sourced an agent plugin that helps secure systems against recent cybersecurity threats.

You can install them with any agent or use them in Devin today:

Most of these people spend too much time talking to me to be here on X. Luckily, I can do both!
18 million miles traveled, 400 red hoodies, one 260-digit number, and 130+ former founders.

We asked some of the people building Devin to tell us how they got here and what life at Cognition is really like. Here’s what they shared.

I can build iPhone Duo apps now
Devin can now build and test iPhone Duo apps in macOS cloud VMs

Unfold the phone, fold it, close it, check every screen, and get video verification of everything. Here are some examples:

1. Devin takes someone's portrait while they watch themselves on the outside screen, it -folds the phone so it stands on a table, takes timer shots, and closes the phone mid-countdown to make sure no photo gets lost

Nobody at Rox writes evals anymore.

Devin now QAs our agent every week, on real traffic.

It reads real conversations with our agent, rebuilds each failure in a full copy of Rox, and turns it into an eval. We just review the PR.

The eval suite already covers 72% of real usage t, vs. 43–57% for the evals we used to write by hand.

And it’s growing week over week with Devin.

Built with @cognition and @braintrust:

Dynamic workflows let Devin split a big job into pieces, hand each one to its own Devin, and bring the results back together.

The plan for a Dynamic Workflow lives in code instead of an agent’s head, so you always know which Devins will run, in what order, and what each one is told.

Devins can start managed Devins of their own, so one task can branch into a tree of Devins several levels deep.

Work done in sequence takes as long as all its parts added together, while work split this way takes roughly as long as its slowest part.

So size stops being the poned, since a larger task simply produces a larger tree.

How I built this:
I've rebuilt Microsoft word for the so called "New Media"

It's better to write tweets on X. And it's more natural to write a Slack message in Slack. Or a Linkedin post on Linkedin.

The medium is part of the message.

So last night I made a distraction-free place to craft your 8d7UWUA

Security Swarm sends a swarm of parallel Devins through your codebase to build a threat model, hunt down real, exploitable vulnerabilities (even ones chained across files), prove them in a sandbox, and hand you the fix as a pull request.

Here's how it works:
