You shouldn't need a meeting to find out if Union works for you. Find us on AWS Marketplace, connect your own cluster, and put a real workload through its paces. You've got 30 days free. Yes, the same Union our enterprise customers use 👀

2 MILLION downloads. And counting. 🚀 Flyte 2 just hit 2M! Huge shoutout to everyone who built, broke, debugged and shipped with us. And there's more 👀 🍎 Your Mac's GPU now works with Flyte devbox. Train locally on Apple Silicon, then scale to a cluster. Same code.

Your Mac is about to become your AI playground. Join @sagecodes and @niels_ai for a live demo of Flyte 2 Devbox: train models, serve LLMs, and build AI agents right on your Mac. Think durable execution, caching, observability, and a path to production. All from your laptop 🧑‍💻 Save your spot: luma.com/trjsr6im

Boston, let's talk molecules, models and making GPUs work smarter 🧬⚡ We're at #AIDDD, Oct 27–29! From scaling scientific workflows to cutting GPU waste and making research reproducible, we've got lots to talk about. 📍 Booth 40, Boston Marriott Copley Place Come say hi! 👋

Fixed the bug. Do we have to pay for the whole run again? No. In Flyte 2 you fork the run with your fixed code, and only the tasks you changed and anything downstream of them re-run. If an infra failure killed it instead, recover the run and only the failed steps execute again. @niels_ai wrote up how each one works 👇

Got plans for Nov 3? We'll be at AWS Loft in SF for a hack night. We'll build a LangGraph agent that tries open models, fine-tunes promising candidates, and deploys the winner, all in your own AWS account. Come spend an evening building with us!
Nov 3rd at AWS Loft in SF: Own Your AI: Build an Agentic AI Model Factory - Hack Night ​We'll start with a walkthrough where we build a LangGraph-powered agent that evaluates open models in parallel, fine-tunes promising candidates, deploys the winner, and retrains automatically when performance drops. ​Along the way, you'll see how Union.aii gives your workflows a durable runtime with infrastructure as context, so agents adapt infra resources, recover from failures, and keep moving without re-running completed work. And because it all runs in your own AWS account, you own the full stack end to end: your models, your data, your infrastructure, your IP. Think of it as the first brick in your own model factory: a repeatable system for evaluating, improving, and deploying models you control! Excited to see people there!

Your queue allows 100 jobs. Each needs 8 GPUs. Your cluster has 16. Enjoy the pending pods. Part 4 of Inside Union covers how we added resource-aware scheduling to Flyte 2, checking demand against quotas and cluster capacity before dispatch. Read the post: union.ai/blog-post/inside-un…

That AI project you keep saying you'll get around to? Bring it tonight 👀 We're hacking on sovereign AI factories at our Bellevue office with @sagecodes, @niels_ai and @GalarnykMichael. Try open models, build agents, experiment with evals or bring your own project. RSVP here: luma.com/9ngtvw3u
We're hosting another hacknight this Thursday (Oct 22nd) at the @union_ai Bellevue office: This months topic is owning your AI by build agentic model factories! @niels_ai and @GalarnykMichael are in town and will be there as well! You'll see how Union ai & Flyte give your AI workflows a durable runtime with infrastructure as context, so agents adapt infra resources, recover from failures, and keep moving without re-running completed work. And because it all runs in your own cloud, you own the full stack end to end: your models, your data, your infrastructure, your IP. ​Then we switch into hack night mode: keep building on the example, bring your own models or datasets, experiment with evals and fine-tuning, extend open models to different parts of your agent, or start something new around the same ideas. Should be fun and i hope to you there!

Last day of #PyTorchConf! We're at Booth 45 until the expo closes.

Using a hosted model shouldn't mean giving up control. Running your own shouldn't mean giving up your development speed. That's our take on sovereign AI: you choose where each workload runs 🧭 and Union keeps it durable as you scale 💪

Follow the curve to Booth 45 👋 We’ll be at #PyTorchConf in San Jose, Oct 20-21, showing distributed training on Union and how to keep an eye on GPU health and utilization in your own cloud. Come say hi to @niels_ai and @cre8minus1!

💥 A 9-hour AI pipeline fails at hour 8. Whether you pay for the first 7 hours twice comes down to which verb you reach for next. Flyte 2 has three, and they differ on whose code runs and what re-executes.

"I waited too long to switch to Flyte 2." That's @PrimaMente's @GanbatJay, after moving a production pipeline in about half a day. Their largest run on Union hit 278,000 actions, in plain Python. If you're still working around your orchestrator's limits, this is worth a read 👇

Last day at AI Engineer NYC 🗽 Thanks to everyone who stopped by over the past three days. If you're still at the conference, come find us at Booth 48 before the expo wraps up. Until next time, NYC!
