Swarms are everywhere, so I got curious how the agents actually talk to each other.
Gave each agent its own @CoreWeave Sandbox, traced every message in Agent Lens, and added a shared memory. They wrote 12 notes. Nobody read a single one.
Also really enjoying gamifying all my demos lately 🎮
More to come on this fun one.

Turn it over into “tent mode” and you can have a fun little auto-updating metric dashboard sitting on your desk.

Lorenzo Porras (@thecodingsoup) built an escape room where Beam repairs a planetary machine, routes light through mirrors, and plans a robot's escape across bridges and doors. Beam receives the rules and state through tools, then writes and runs Python in @CoreWeave Sandbox to solve the puzzles. A 3D room shows the run as it happens.

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. crwv.co/utSf3

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.

During @reflection_ai’s private preview of Beam, I built a haunted escape room to put its coding and reasoning to the test.
I created a game called “Code Your Way Out”, and it's one room with three linked puzzles. Beam has to repair a brass orrery by lining its rings up with a constellation, route the light, then program its escape through a sealed hatch.
Beam never sees the room. Each turn, it gets text observations and writes Python; the code runs in a @CoreWeave Sandbox, and the game engine validates every action before the explorer robot moves.
Beam was out in about 30 seconds. Super bullish on this model and really excited to see builders get this model in their hands.

The @NVIDIAAI team shipped Nemotron 3.5 Super VL today, and you can call it now on CoreWeave Serverless Inference.
Send it text and images, build with supported reasoning, tool calling and structured outputs, and trace every call in CoreWeave Agent Lens.
It's a multimodal mixture-of-experts model with 12B active parameters, served in NVFP4.
Pricing per 1M tokens is $0.25 input, $1.50 output, and $0.05 cached input.

@CoreWeave Agent Lens already supports OTel, natively. All you have to do is configure your endpoint and we'll slurp all your Claude traces into CoreWeave Forge's purpose built UI. You can do this literally right meow.

CoreWeave Model Distillation is in preview in CoreWeave Forge.
Start with a teacher that has "the best big model smell that you can get," as @altryne put it on ThursdAI, and let it teach a small student your one task. GLM-5.3 and its Flash variant are the familiar example.
The student is quick at scale, and that one job stops costing frontier prices.

Your agent handled 40,000 conversations overnight. 230 went wrong. No alarm. All 230 reached customers.
That is why CoreWeave Agent Lens exists.
Log your agent's traces and it reads the entire production corpus, not a sample.
It groups the conversations that fail the same way, even when the wording or the tool sequence differs, and links each group to the traces that prove it. crwv.co/utcU7

Your agent made a mistake. Can you turn it into a test?
Zubin Aysola (@wandb) turns an ARIA production trace into an eval and benchmarks the fix.

🪙 Platinum. Three reports in a row.
@SemiAnalysis_ published ClusterMAX™ 3.0 today, and CoreWeave is the only provider rated Platinum in all three editions.

our SENPAI autoresearch found a nice 22% drop in training time for us via writing:
- SliceAttention kernel (we're using Transolver atm)
- BatchedMuon
4 hour saving for a full training run, 26h -> 22h, no significant change in error/quality

Marin's hero run is training on our @wandb, and a ten-person open lab is showing everyone how a 535B model actually gets built.
Pull up a chair to the show: wandb.ai/marin-community/mar…
Glad to see another live training run! Here's how Marin 535B-A23B is doing today: wandb.ai/marin-community/mar…
Anyone else want to share?
