We started this project only 6 weeks ago. It's the first model we trained with a midtraining stage, combined with many improvements in RL. The biggest relative gains compared to a base model we've achieved so far.
One goal we've been thinking about is how to provide the benefits of open weights without the cyber safety risks. The ability to run models on our own infra or post-train them was crucial when we got started, so we want to give back to the community. On the other hand, increased cyber capabilities in the hands of bad actors are becoming a major risk, e.g. the recent Binance hack by hacker group in North Korea - the largest heist in human history.
We're working on a program that allows us to hopefully get the best of both worlds (with some compromise). Under this program, we would be able to share the weights securely with enterprises, industry partners, and research groups - without risking abuse by bad actors. We're still working on the details and will share more in a few weeks, especially as we release even stronger models.

Introducing SWE-2 Flash, our new fast & efficient coding model.
On leading evals, it outperforms all American open-weight models, even ones 3x larger.
To balance transparency and cyber risks, we are building a program to securely share the weights with partners & researchers.
Here’s the newest eval I’ve been making with our research team!
Introducing FrontierCode 2.0: our new coding benchmark that measures a model’s ability to go beyond the spec.
Most coding evals measure a model’s ability to write code that meets a spec. With FrontierCode 1.0, we asked a new question: would you actually merge the PR?
FrontierCode 2.0 is comprised of more diverse tasks, featuring larger scopes and higher mergeability standards. We are now asking: not only would you merge this PR, but should you?
One key feature of FrontierCode 2.0 is underspecified prompts. Rather than including every engineering decision, prompts are deliberately ambiguous, giving the models room to demonstrate their judgment.
The result is a benchmark that is far from saturated, with the top model scoring just 45%.
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:
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:

Me and Devin are using @DevinAI to train and deploy custom models on @modal, and it’s easier than you’d think
This is a good basic template to get you started

Calling all SF startups! Join us for the Pylon x Devin Launch Party Thursday, October 29.
Grab some swag, a drink, and chat with Cognition CPO @walden_yan and Pylon CTO @advith_c about our support → engineering flows.
New Devin customers on Pylon can also pick up $15,000 in Devin credits.

Most of these people spend too much time talking to me to be here on X. Luckily, I can do both!

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 sends posing cues, half-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 happening in the product, 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:
PagerDuty just pinged me. Investigating now, go back to bed.

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.
Devin retweeted
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 reason a task gets postponed, since a larger task simply produces a larger tree.
