Somewhere, someone has been carrying a question for years.
We built The Essential Cloud for AI to get them closer to an answer. Today that message is on the Exosphere at @SphereVegas.
Discovery is a human pursuit. We’re built for yours.

@TheCodingSoup wanted to see how AI agents talk to each other when they work as a team.
So he gave a swarm a shared memory and let them do their thing inside of a @CoreWeave Sandbox. They wrote 12 notes. Not one got read by another agent. (Every agent was traced in Agent Lens, so we could check.)
The next run changed the timing: leads shared plans before starting, and each new agent got the relevant notes with its task. No duplicated experiments that time.

What does it really take to scale AI infrastructure?
Scale isn’t just about growth – it requires constantly reimagining and optimizing system architecture as workloads multiply.
On the latest episode of AI Cloud Essentials, @VAST_Data Co-Founder & CTO Alon Horev joins Ritu Jyoti to unpack the massive scaling vectors ahead.

Today, your agent asks the web for what it needs.
@paraga expects a lot of that to flip in three years, with systems like @p0's pushing information that wakes an agent up to start work.
Agents on CoreWeave can enable Parallel's search with a single setting.

ICYMI: Our first capacity in Denmark is now online 🇩🇰
We deployed 22.5MW at atNorth's DEN01 in Copenhagen, our ninth data center in Europe.
@SemiAnalysis_ has rated CoreWeave Platinum in ClusterMAX three times in a row for a reason. crwv.co/uuuYp

Karpathy got annoyed with YouTube recs and built HackerTube in a weekend. Yours was probably manually lining up logged images to check a single detection.
New in Weights & Biases Models: zoom or pan one image and the rest follow at the same zoom level and position. Bounding boxes, masks, and class labels move with their images.
It's on by default, so the cropped screenshots can retire. crwv.co/uurrz
Today at Fal.Con Europe, CoreWeave and @CrowdStrike announced an expanded strategic partnership for production AI.
That puts CrowdStrike Falcon protection and 24/7 threat hunting on CoreWeave Cloud. Your GPU clusters just got a night shift.
Falcon Complete Cloud Security runs detection and response through full remediation.
We also provide the infrastructure supporting training and inference for CrowdStrike SafeMind. crwv.co/uuqTX
Real-time AI lives or dies on latency. Find out how yours holds up before you scale.
CoreWeave ARENA gives you 14 days on production-grade AI infrastructure, a CoreWeave AI expert, and ARIA reading your traces. You leave with real performance and cost evidence.

What is the real multiplier effect when @PwC tapped CoreWeave Cloud?
It comes down to output – ensuring organizations move beyond raw infrastructure to reliably deliver the results and value their teams and customers expect. Dallas Dolen joins the AI Cloud Essentials podcast to break down how the collaboration delivers end-to-end impact: crwv.co/utOLj
Reinforcement learning moves fast. But sometimes, training and rollout serving don’t.
Join @youdotcom, @NVIDIA, and CoreWeave on November 19th for our webinar Closing the Loop Between Inference and Post-Training. Register here: crwv.co/uuezt
Throttled GPUs waste money. Catastrophic leaks kill clusters.
At #FullyConnected26, Jacob Yundt (VP of Engineering, Compute Architecture at CoreWeave) broke down Valvey – programmable liquid cooling built to safeguard next-gen AI compute:
🔹 10-second automatic rack shutoff to stop leaks before damage occurs
🔹 Software-driven telemetry monitoring flow rate, pressure, and temp continuously
🔹 Zero thermal throttling for 100% liquid-cooled Vera Rubin NVL72 architectures

What made CoreWeave Cloud the best choice for @PwC?
Dallas Dolen joins Ritu Jyoti to break down how combining CoreWeave’s compute capacity with PwC’s transformation expertise accelerates enterprise AI adoption.

In collaboration with CoreWeave, we show how our autonomous system optimizes LLM inference end to end, from engine configuration to custom GPU kernels: up to 63% more traffic for GLM-5.3, 2x per-user throughput for Qwen3.8-27B, and 10% more throughput for DeepSeek V4.1 Flash. 🔗
Today we're taking the CoreWeave Global AI Network to the Middle East and Asia Pacific, on a backbone that runs at Petabit scale.
That's enough to stream a 4K movie to 66 million people at once. We'd rather move your datasets and checkpoints 🍿😉
All of it moves encrypted with MACsec, in hardware at line rate, across the backbone and inside our data centers, so security doesn't cost you throughput.
New points of presence in the UAE, India, Indonesia, Singapore, Australia, South Korea, and Japan are coming online beginning in Q4, bringing the network to four continents. crwv.co/uua8r
CoreWeave Forge is now the default endpoint in the @wandb SDK.
That means one account and one API key for your runs, your traces, and CoreWeave Serverless Inference.
The key you already have keeps working, so nobody needs to log in again 😌
See what's new in 0.31.0 below.
wandb 0.31.0 is out now, and import wandb and the CLI start about twice as fast.
That's for builders like @Vanzllll, whose DiffusionART team "found some surprising answers" after nearly 800 wandb runs.
Now find yours.
It also grows W&B LEET, the terminal UI for exploring W&B runs. wandb leet inspect --summary reads a run's local .wandb file, and --json prints that as JSON for a coding agent.
pip install -U wandb
We just shipped four new panel types in CoreWeave ARIA, our AI Research and Iteration Agent 🚢
Parallel coordinates, parameter importance, run comparer, and media panels now render live in the chat, so you can check its work in the thread. crwv.co/ut1iG

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
nice try
we spun up 700 boat.dev VMs 4c x 8gb, started codex + minecraft, made it all play in multiplayer together
they all booted from a snapshot in the first 10s, which cost $0.07, same price per VM, core & ram
but much more impressive capabilities and scale

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. crwv.co/ut17n
