SWE-2 is now available in Devin Desktop and CLI!
We're offering unlimited usage for all Pro, Teams, and for the next month!
From Software Factory to Model Factory
@TheWuster from Cognition uses @DevinAI to train a custom image model on @modal, deploy it, and ship it into a product

Devin Fusion with Claude Opus 5.5 (max) and a GPT-6 Luna (high) sidekick scores 68 on the Coding Agent Index, 2 points above Claude Code with Opus 5.5 (max) at 31% lower cost per task
@cognition's Devin Fusion runs a frontier lead model alongside a lower-cost sidekick model. The two work in parallel with their own context and tools, with the lead keeping planning, delegation and final review. We benchmarked Devin Fusion CLI with Claude Opus 5.5 (max) + GPT-6 Luna (high).
It scores 68.1 on the Artificial Analysis Coding Agent Index, closely matched at the top with Claude Code with Claude Sonnet 5.5 (max) at 68.4 and Muse Code with Muse Wonder Full (max) at 68.0. Against Claude Code with Claude Opus 5.5 (max) at 66.0, it costs $9.01 vs. $13.04 per task and averages 55 vs. 65 minutes per task.
Across the three benchmarks, the Fusion configuration scores higher on DeepSWE v1.1 (72.6% vs. 68.4%) and SWE-Atlas-QnA (69.6% vs. 66.4%) and slightly lower on Terminal-Bench 4.0 (62.1% vs. 63.1%). Its results reflect both models working together, including their combined API cost. Costs are pay-per-token API costs, not subscription prices.

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

Devin Fusion. Better and cheaper.
Devin Fusion has claimed a top score of 68 on the @ArtificialAnlys Coding Agent Index with an Opus 5.5 lead and GPT-6 Luna sidekick.
Devin Fusion outperforms Claude Code with Opus 5.5 on both performance and price – earning a score of 68 at a 31% lower cost per task.

The number of Alliance startups using @cognition has now surpassed the incumbents, which says a lot about what they’re building.
Between the hands on support they provide founders and the generous perks they’ve contributed to our startup program, the team is genuinely going the extra mile to help our founders succeed.
Huge shoutout to the entire team.
Devin Developers retweeted
This is directionally consistent with our internal data @cognition. Many tasks within software engineering are now "intelligence saturated." Once any model can do the task well, cost and speed are all that matter.
OpenAI, Anthropic and other leading AI labs face a growing challenge: Better models aren't necessarily attracting more usage. A 10-point intelligence advantage now earns just 20% more developer traffic, down from nearly 69% in late 2025.

Our eng team put Devin on the on-call rotation. It investigates alerts, finds the root cause, and opens a tested PR for review.
Excited for our friends at @cognition to be officially launching this one!

Huge congrats to @cognition for taking the #1 spot on #SREGym! 🎉
It’s been incredible to have a front-row seat to the progress in AI SRE. Shoutout to @anhangz, @yunpark93, and @jake_rachleff for an amazing release pushing the frontier of autonomous incident response.
One step closer to a world where humans don't have to be on call. 🚀
SREGym 1.1 is out now, with 2.0 on the way to push the frontier even further.

iPhone Duo on Devin Cloud
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

How to use Devin to automate evals from production traffic.
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.

Engineers are realizing they don’t need to lose as much sleep while on call anymore.
Correspondingly, usage even while in private beta has been explosive

Devin Oncall is finally here! We took all of our learnings over the last two years around making agents good at resolving production issues, and taught Devin to do it all.
Self-driving software is here.
