The traffic sucks. Everything's expensive. But living in a place where convos abt physics, CS, and math are the daily norm rules.

ICYMI: Jensen announced on stage at #NVIDIAGTC at Computex we’ll be among the first cloud providers to bring up @nvidia Vera Rubin NVL72 to power agentic AI factories worldwide. Setting a new bar for operational reliability and resiliency at scale. LFG⚡️

We have the first @DellTech @nvidia Vera Rubin NVL72 @CoreWeave. Here we go! 🚀

Introducing CoreWeave Sandboxes, now in public preview. It's the execution layer for RL, agent tool use, and model evaluation, on your own CKS clusters or serverless through @wandb. Get the details: hubs.la/Q04gxM2L0

The Google Threat Intelligence Group has detected the first known instance of a threat actor using an AI-developed zero-day exploit in the wild. While the attackers planned a wide-scale strike, our proactive counter-discovery may have prevented that from happening. This finding is part of our new report on AI-powered threats.

It's fun to be back in SF and see the energy and spark in the city again. Very noticeable the change from a year or two ago. City feels more vibrant, safer, and cleaner.

In 2004 the Sun Fire E25k was the apex predator of computing. This was the largest single-image Unix machine that money could buy ($2M fully loaded). This bad boy had: • 36 UltraSPARC IV processors (72 cores) • 576 GB RAM • 18 fully hot swappable CPU/memory boards • gigabit ethernet and fibre channel HBAs • Redundant power supplies, cooling zones, draw 15kW of power I deployed software to these things. Uptime was measured in years. This was THE ONE. Man I miss Sun.

CoreWeave is one of the first cloud providers to achieve @NVIDIA Exemplar Cloud validation for inference on NVIDIA GB200 NVL72. Following our training validation, we’ve now proven peak performance for the full AI lifecycle on Blackwell, meeting targets for DeepSeek-R1 and Llama 3.3.

I have a few regrets in my career. Not being able to complete an investigation into Salt Typhoon as part of the USG’s Cyber Safety Review Board is creeping to the top of that list. Unfortunately I’m not surprised to see this news emerging in the UK, as I suspect the intelligence gathering is pervasive across many countries. And unfortunately I’m not surprised to see legally mandated backdoors (lawful intercept systems) exploited for adversarial gain.

Masked agents of the US state are executing people in the streets and powerful leaders are openly lying to cover for them. To everyone in my industry who’s ever claimed to value freedom—draw on the courage of your convictions and stand up.

Ghostty is now a non-profit project, fiscally sponsored by Hack Club. mitchellh.com/writing/ghostt… I view terminals as critical infrastructure that should be stewarded by a mission-driven, non-commercial entity that prioritizes public benefit over profit. Ghostty is now that.

AUP SUP automates provisioning/management of user credentials from your existing SCIM-enabled IdP and secrets management infrastructure to CKS and SUNK. Excited to build the first hyperscaler that natively leverages your existing cloud self managed infra to protect your data.

Complex clusters = complex challenges. Join @CoreWeave experts Amit Gupta & Tara Madhyastha on November 24th at 1PM ET to learn how AI-native observability enables faster, more resilient workloads—from the application layer to bare metal. Register here: hubs.la/Q03SVDpW0

CoreWeave is the #1 AI Cloud once again. In today’s @SemiAnalysis ClusterMAX™ report, CoreWeave was the only cloud provider ranked Platinum – a testament to our unwavering dedication to excellence. Read the full rankings: hubs.la/Q03S2wvr0 #SemiAnalysis #ClusterMAX

Excited for my team and I to have been a small part of this!

Software as Self-Expression There's something intimate about building software that I don't think we talk about enough. When someone uses something you've made, they're seeing the world through your lens. They're adopting your mental models, even if just temporarily, to get something done.
