2 days → 2 hours.

kinda crazy how often devin users i interviewed would say this about one session.

companies are busy cutting ai spend when they should be measuring it. the value is there. you just have to prove it.

LLMs when I ask them for a plan: "this 30-min refactor will take 2 days"

LLMs when I give them the full session trace + hill climb the prompt: r_log of 0.74

context and prompting is everything

AI should earn its keep. Introducing the AI Productivity Guarantee.

If Devin delivers less engineering value than you’re paying for, Cognition will fund your usage until it does, up to $10 million.

It’s time for the AI industry to stop maximizing tokens and start maximizing productive output.

they say you become the average of the five people you spend the most time with, so I've taken some precautions

Ryan @ryanbai is known for his iconic red hoodie, so for his birthday, everyone at @cognition got their own.

Windsurf is now Devin Desktop. Cloud + local Devin, all in one surface.

[Cognition @cognition]

Introducing Devin Desktop.

Manage fleets of local and cloud agents from one surface. Plan, delegate, review, and ship without leaving your editor.

here we go again

[Ryan Bai @ryanbai]

Been a blast working on this!

Current AI review tools focus on being an end to end reviewer, but it's also important to augment the human and make it easy for them to understand the code and what's going on.

Give it a try!

we didn’t come up with simulation theory until we invented computers. makes me wonder about all the theories we can’t even currently imagine because the tech isn’t there yet.

Found out today that every IOI since 2006 had at least one Cognition employee competing in it.

Agents are starting to get scarily good at computer use... It's soon gonna be a massive game changer in the way people use Devin.

[Cognition @cognition]

Devin now has full computer use capabilities and can share screen recordings.

You can control desktop apps, build and QA mobile apps, and automate tedious work.

Here are some examples that blew our team away:

1. Making a desktop game

@armiksos @itsandrewgao thanks so much for the info! ctrl+shift+p > open settings (ui). it should be in there. (mostly was wondering if you could quickly test if there are issues with cmd or git bash by just asking cascade to run some terminal commands)

[Ryan Bai @ryanbai]

@GarrettPullis @itsandrewgao Quick questions to help debug (would be super helpful): What OS are you on? What terminal do you see when you create a new default terminal? And do the issues go away if you switch to some other terminal (Settings > Terminal › Integrated › Default Profile)

[Ryan Bai @ryanbai]

@marvijo99 @itsandrewgao @windsurf Quick questions to help debug the terminal issues (would be super helpful): What OS are you on? What terminal do you see when you create a new default terminal? And do the issues go away if you switch to some other terminal (Settings > Terminal › Integrated › Default Profile)?

@armiksos @itsandrewgao Assuming you're on windows? What terminal do you see when you create a new default terminal? And do the issues go away if you switch to some other terminal (Settings > Terminal › Integrated › Default Profile)

Windsurf feels sooo much nicer to use than a couple weeks ago. Also super excited about where we’re heading, a lot to explore in the IDE space!

@rpeng233 Ya, would not have guessed competitive programming would be one of the first to fall. Wanna say probability of ai beating me (when taking union of scores across all labs, given near infinite compute and submissions) is at least 30%…

[Ryan Bai @ryanbai]

Darn almost can’t believe it’s my last IOI already. Huge thanks to @rpeng233 for coaching and supporting me over these years ❤️.

Cognition is the first AI lab to win a verified gold medal at the IOI. Our human, ryanbAI (@ryanbai), placed 7th overall. Impressively, ryanbAI competed under the exact same conditions as all human contestants.
