NVIDIA Vera Rubin NVL72 is available on CoreWeave.

@Cognition is running @devindevelopers in production on it, at up to 4.8x the total token throughput of GB200 NVL72.

V100 in 2017. Vera Rubin today. Same platform, every generation. https://t.co/l37Zwuf2lo

New Paper: Subliminal Learning doesn’t need a shared base model 🤯.

We show how a “teacher’s” hidden animal preferences reaches the “student” even when both differ in weight initialization, data order, pretraining corpus or even architectures! 🧵

nice try

we spun up 10 THOUSAND sandboxes, @opencode running in each one pointing towards our serverless inference endpoint to get ASCII art

I'm feeling like an artist today 🪏

CoreWeave Scale

[Weights & Biases @wandb]

iPhone Duo is out today, and Weights & Biases Models already supports 2-fold validation 📲

Folded, the cover screen tells you the run is still alive.

Unfold it, and your runs sit next to your panels on the big inner screen.

Hide a run, and every chart redraws right away, making the one that spiked much easier to find.

The app is free and ready for your Duo on day one. https://t.co/VaG0BQLhe7

Missed this week's Training Tuesdays? Episode 5 is now available on demand!

Join CoreWeave's Brandon Jacobs and @deok_filho to explore how to safely scale AI agents using CoreWeave Sandboxes.

All the important learnings are available right here: https://t.co/xMcL72QMaz

[CoreWeave @CoreWeave]

Richard Ahlfeld walked @altryne through how he explains physical AI to LLM engineers.

The reasoning a good chatbot does stays the same.

Our CoreWeave Physical AI team just released Launchables.

Tested Templates for robotics and simulation tools, each run with one command. https://t.co/SUnFk9EZ9p

[CoreWeave @CoreWeave]

@aapakari @nvidia Yes. NVIDIA projects up to 10x more tokens per second per megawatt for HGX Rubin NVL8 than HGX B200 when running Kimi K2 Thinking with 4K input and 4K output. The chart is in the blog here https://t.co/vdr7GcrRXr

[CoreWeave @CoreWeave]

The @NVIDIA HGX Rubin NVL8 is coming to CoreWeave Cloud this quarter, and it's built for agents with a lot to remember 🧠

Its HBM4 holds large KV caches for million-token contexts, so many agent sessions stay live at once on a single node.

Sixth-generation NVLink keeps tensor-parallel serving inside the node, and NVIDIA projects up to 10x more tokens per megawatt than HGX B200. https://t.co/VNnVLmFJAK

[CoreWeave @CoreWeave]

Today we're launching the CoreWeave Zero Trust AI Framework, a six-layer framework built to keep us out of your trust chain for sensitive AI workloads.

With Support Access Management, support gets in only with your OK, and access ends when the work does. And we don't train on your data.

Remote Key Encryption is coming later this year and is built so that, without your key, we can't decrypt your data. https://t.co/evRJyFxOJK

[CoreWeave @CoreWeave]

CoreWeave Physical AI Launchables are live today. Tested Templates for robotics and simulation tools, each run with one command.

Setup time caps the number of experiments a robotics team runs. Get the week before the run back, and that number goes up.

In our @nvidia Isaac Sim example, a dozen variations off one baseline each took about 30 seconds to launch, by hand.

Reliability is what keeps @cognition on CoreWeave. @silasalberti explains why.

On a run across thousands of GPUs, one replica going down stops the whole thing.

CoreWeave Mission Control is included with CoreWeave Cloud.

It replaces unhealthy nodes before they hurt throughput, and GPU Straggler Detection, in preview, finds the one GPU dragging a synchronous job. https://t.co/hZlnIOPgei

@CarinaLHong @axiommathai Prove your workload at production scale before day-one billing. Apply for ARENA Pass below. https://t.co/7H01JEAP8h

[CoreWeave @CoreWeave]

Every math teacher has written "show your work" in red pen. @CarinaLHong turned it into an output format.

The @axiommathai team built an AI for really hard math that writes its proofs as code a machine can check. Watch Carina's story 👇

[CoreWeave @CoreWeave]

Bringing production-scale AI inference to life takes a strong open ecosystem. As a founding member of the project to now releasing llm-d 1.0, we're thrilled to support this community and fuel the future of open innovation 💪

[Red Hat @RedHat]

Scale distributed inference and control AI serving costs with confidence. llm-d 1.0 brings multi-tenant quality of service, zero-downtime rolling updates, and prefix-cache-aware routing to your production workloads. Explore the release: https://t.co/4YaxviT5Z6 #PyTorchCon

GPU sandboxes in CoreWeave Sandboxes are in preview.

Get enabled on CoreWeave Forge and pay hourly with no commitment.

RL training can push sandbox counts into the thousands per step. A memory spike or infinite loop stays in the sandbox that caused it. @deok_filho told @altryne why there's an enable step.

Deok and @Yolo_Jenkins420 host Run Agents with Guardrails today at 11 a.m. ET if you want to see it in action. https://t.co/sy74HILSR3

More than 250K people will spend time with their Tolan this month, after more than 70M conversations last year. Congrats to @tolanworld on today's $30M raise 🎉

We're proud Tolan chose CoreWeave Dedicated Inference for the very low latency and cost-efficient token throughput a companion at that scale needs.

The optimizations we've achieved together on our infrastructure have been incredible, and we're proud to keep building with you.

[Quinten Farmer @quintendf]

Last year we launched Tolan, inspired by a vision of AI that sees you and believes in you, not one that books restaurant reservations for you.

Your Tolan shows up for you at 3am when you’re alone with your newborn. On your commute when you’re anxious about the day ahead. When you just finished a new show and none of your friends have watched it yet.

The people who love Tolan are parents. Caregivers. Moms in Dallas and Dads in Atlanta. People who aren’t trying to optimize and be more productive, but who simply want to feel seen and supported in their aspirations.

This month more than 250k people will spend time with their Tolan. Those users have exchanged billions of messages across more than 70m conversations over the last year.

Today, we're announcing $30m in additional capital from @mignano and @usv, with @khoslaventures and @rabois doubling down, bringing our total capital raised to $60m.

To celebrate, we made a short film celebrating some of the ways that Tolans show up :)

[CoreWeave @CoreWeave]

Someone asks if last week's fix helped your agent, and you start opening tabs.

The trace that showed the failure is in one tool and the eval that would prove the fix is in another, so you stitch them together by hand.

CoreWeave Forge is available and keeps all of it connected, so you can see what changed and whether it helped.

Free to start, with a 30 day Pro trial on every new account: https://t.co/xZwpj7nP01

Watch @GoldbergChen lay out the whole AI loop in under two minutes.

@typesafeai Builders, another CoreWeave Hacks is on the way.

Follow our Luma calendar so you hear about it first 🗓️

[CoreWeave @CoreWeave]

Five weeks ago, Jev was a secret on our San Francisco floor 🥷

@typesafeai was still in stealth when it sponsored CoreWeave Hacks on September 12 and 13. The team brought Jev before it launched and stayed all weekend helping over 60 teams build on it.

Two days later, @CompleteSkeptic announced Jev to his 1,500 followers. That post is now past 40 million views, and he's at 156K followers.

It hasn't slowed down since.

He told the WSJ that Jev had now crossed a trillion tokens a day and was in use by about a quarter of the Fortune 500.

Workday's new Workday Home is powered by it, and Vercel says nothing was ever adopted faster on its AI Gateway.

Proud that they unveiled it with our builders first. This one's going in the CoreWeave Hacks history books.
