8 years and we're still just getting started! 🙌

Exciting launch: Pulumi Cloud can now serve as a Terraform state backend! Migrate your state in minutes — keep using the Terraform CLI while gaining encrypted state, RBAC, audit policies, and unified resource visibility across your entire infrastructure estate. hubs.ly/Q045PxVF0

One of the best (non-coding) vertical agents that I’ve tried is @PulumiCorp’s Neo “Hey I’m trying to set up cloudshell so it can touch XYZ resource - tell me which existing security group I should give it and which subnets to put it in” Nailed it on the first try, well done

New art project: Foundations of LLMs. 71 of the most influential papers in the history of large language models, from McCulloch-Pitts neurons (1943) to modern reasoning systems (2026), curated into a single 2,381-page volume. Every paper had to clear a high bar: it pioneered a direct ancestor of modern LLMs, or later breakthroughs couldn't have happened without it. It opens with an artful microGPT portrait inspired by @karpathy. Seeing 200 lines of gorgeous Python before diving into the deep science and math is awe-inspiring. This book has supplied me many eves of learning and fun thus far and I hope it does for you too.

@samrags_ @fabianlindfors @specific_dev @SST_dev SST is incredible. If you want something more like TF but with more in distribution languages like Python, give Pulumi a try. Claude likes it.

@fabianlindfors @specific_dev I really like @SST_dev will give you guys a go

I used to think Vercel would win the AI era. They're AI native and dev-friendly But now Claude one-shots AWS deploys from CLI, for 10-100x cheaper hosting

We also open sourced many skills that make Neo tick so you can use them from any agentic tool: pulumi.com/blog/pulumi-ag…

We spoke to several people this week who now use our infrastructure agent Neo to do *everything* in the cloud. They don't look at or touch IaC, cloud consoles, etc. Agentic clouding is here!

Clawdbot got renamed to @openclaw! Time to update my blog post too! And used to opportunity to update the meta image too! 😆

Want to Clawdbot but don't have a Mac Mini? No worries, here's how to run it on AWS (with Pulumi and Tailscale). pulumi.com/blog/deploy-cl…

✅ ralph can do the job of a devops engineer ✅ ralph enjoys psytrance

Nice, @tldrnewsletter is excited about this too 🙌

We sped up IaC updates by 20x through some pretty deep technical wizardry. Love this post from the team, which explains how we kept high reliability while reaping the perf gains. Akin to database transaction journaling. Hopefully makes users happy! pulumi.com/blog/journalin…

The limits in 2026: good ideas, good taste, bandwidth, and time.

@gkingofboston I put it in my CLAUDE.md, but frequently have to pull it out and remind Claude when they misbehave. It also works good for commit messages.

@funcOfJoe Where would you put this? System prompt or Claude .md?

So basic but instantly leveled up Claude Code's comments.

give claude code pulumi and ansible and it can really run anything anywhere
