Demand for SWE-2 in Desktop & CLI is unprecedented. Glad to announce, we were able to secure additional compute. We're making SWE-2 free in Devin Cloud for Pro, Max & Teams subscribers - until October 8. Enjoy!

The most technically interesting part of this was building a self-improving AI loop Traditionally we think of coding agents as tools to do work faster, but we are quickly moving into a world where async agentic work is fully decoupled from human work This means you can build an AI system that is fully self-improving & can perform experiments and react to results. Based on OpenClaw-style heartbeats, we built a similar system using a bunch of Devin automations: - Calling: Agent dialed restaurants in a morning and an afternoon window on weekdays. - Review: Agent read every transcript afterward and edited the phone agent's prompt. - Idea: Agent once a day, picked one new thing to try. - Webhook: When money or a call came in, an event woke a fifth kind of Devin to handle it. Every ~20 minutes a heartbeat ran in the form of a Devin automation. Each heartbeat is its own Devin session + its own sandbox VM. They all begin by bulling down the "brain" from s3 Read more about the architecture in the quoted article

News is out: I joined Cognition, and SWE 2.0 is now generally available. It’s been a pleasure locking in with the team to ship our best coding model yet. Here’s to many more releases together. In the last few days: $2B raised, a model launch, and we’re not done yet for the week. Stay tuned. To celebrate, here’s SWE 2.0 drawing an otter:
