This was my initial vision and pitch for @turborepo: a build system that worked the same way locally and in the cloud that felt completely idiomatic to your codebase, with as little configuration as possible.
Traditional YAML CI didn't make sense back in 2021 and it makes even less sense now. The biggest pushback against a turbo-first CI was that it was fairly painful to lift all the bash slop into real packages in your dependency graph, but of course now that's trivial for agents. Congrats to @anthonyshew @rauchg et al for executing.
Introducing Vercel CI
• Intelligently skips tasks with Turborepo
• 2-6× faster CI in our internal repositories
• Optimized for agents via Vercel MCP and CLI
After nearly 8 million tasks, we're excited for the future of agentic CI. In beta on all plans.

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%.
We’re rolling out Devin Security 2.0, our new autonomous defense factory. We’re also committing hundreds of millions of dollars in free credits for enterprises for scanning, verification, and remediation.
Last week we released a totally refreshed Devin Desktop app. We unified our IDE and our agent-first experience so you can switch seamlessly between cloud and local. This is the first of a few upcoming ships that unify our client surfaces so Devin feels and works like Devin no matter what device you’re on.

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.
One-size-fits-all blanket usage caps on AI spend don’t make sense. On the other hand, yolo tokenmaxxing doesn’t scale either. We’ve come up with a better approach to cost control centered around efficiency. More efficient employees can have limits raised automatically (with a final upper bound still), while other spend requests go thru an admin review process.
What if your AI budget went to the engineers who use it best?
Blanket usage caps are a hiring freeze in disguise.
Introducing efficiency-based auto-approvals for your most productive engineers, plus Devin Coach to help everyone get there.

I could be wrong, but from my understanding, without months of weight training, normies will not have the neck strength to tolerate the g force at this speed. You’d would only last a few laps at best before your neck gives out
Tesla Roadster could be 5 s faster than F1 at COTA.
I simulated a lap with the revealed specs: 1:27.9 vs Verstappen's 2025 pole at 1:32.5.
Where it wins: acceleration. All-wheel drive, 2 g of fan suction keeping the tyres planted on exits, and cold-gas thrusters. Top speed on the back straight: 374 km/h vs 324. At the end of the lap the temperature in the tank is -150 Deg C.
Where F1 wins: braking and the fast corners. An 800 kg car with downforce that grows with speed beats a 2-tonne one.
As @elonmusk said the tires are the biggest limiting factor, I assumed quite conservative values taking into account the massive vertical forces that they would have to endure.
We productized how we handle incidents, bug reports, and alerts at @cognition with Devin Oncall. It’s completely changed how we work and also how we think about incident management and SRE. From investigations, to reproductions, to triage, rollout, root cause analysis and even postmortems, we do it all with Devin. Excited to share this with the world.

mise is really good. i switched from homebrew on my work machine and have had a wonderful experience so far
new in mise: tools that keep themselves up to date.
set auto_update on a global tool and mise upgrades it right before it runs. optionally run a daemon to do upgrades in the background.
