Four point eight times. The number is a customer's, even though NVIDIA publishes it, and that makes a difference.
Cognition, who make Devin, have not been selling Vera Rubin to anyone. They took tasks from FrontierCode, set agents to solve them and compared against the previous GB200 generation. One customer's test on one workload, but at least it is their workload.
Fact
The facts: on 30 September 2026 NVIDIA said CoreWeave had announced availability of NVIDIA Vera Rubin NVL72 systems with Spectrum-X 102.4T Ethernet networking, and that Cognition, the company behind Devin, is the first customer running production workloads on Vera Rubin. CoreWeave received its first production racks earlier in the month. In early tests Cognition saw up to 4.8 times higher total token throughput for SWE-2 inference compared with GB200 NVL72, on a sample of FrontierCode tasks. CoreWeave will also offer the Vera CPU: 128 CPUs and 11,264 cores in a single rack, enough for over 11,000 concurrent isolated environments at one core each; in testing, agent sandbox startup was more than 3 times faster. CoreWeave also launched Forge, which brings together Weights & Biases, OpenPipe and marimo for continuous improvement of models and agents. Per NVIDIA's Ian Buck, CoreWeave's V100 GPUs are still running customer workloads nearly a decade after Volta launched.
Part of the weight is in the CPU. An agent needs a sandbox, and reinforcement learning needs thousands of sandboxes at once. A rack with more than eleven thousand isolated environments answers exactly that need.
Agent sandboxes are now counted per rack.
The line about the V100s is nice too: the old cards still work nearly a decade on. It is advertising, of course, buy today and it will run for years. But it is also a rare reminder that old iron does not die on the day the new one comes out.
The next number has to come from someone the seller is not quoting.
