SUNK: Production-Ready AI Training at Massive Scale

As AI training runs grow longer and clusters scale to thousands of GPUs, reliability and operational consistency matter as much as performance. SUNK is CoreWeave’s production-ready training system built to run large-scale AI workloads without manual cluster tuning. With topology-aware scheduling, automated health management, and self-healing infrastructure, SUNK keeps long-running jobs efficient and resilient, even at frontier scale. CoreWeave Cloud. The Essential Cloud for AI.

1

00:00:00,266 --> 00:00:04,500

As AI research clusters

grow larger and training jobs run longer.

2

00:00:04,666 --> 00:00:08,566

reliability, goodput

and operational consistency matter

3

00:00:08,566 --> 00:00:10,600

as much as raw performance.

4

00:00:10,600 --> 00:00:14,866

But the last thing you want to do

is manually tweak a thousand-GPU cluster.

5

00:00:15,133 --> 00:00:19,766

That’s why CoreWeave built SUNK—

a production-ready, training first system

6

00:00:19,766 --> 00:00:25,166

that lets you confidently run large-scale

AI training without operational overhead.

7

00:00:25,900 --> 00:00:32,300

CoreWeave sunk brings cloud-native scale

and agility to AI training environments built for research.

8

00:00:32,300 --> 00:00:34,000

By optimizing job placement

9

00:00:34,000 --> 00:00:36,133

and automatically managing cluster health

10

00:00:36,133 --> 00:00:37,866

through CoreWeave Mission Control,

11

00:00:37,866 --> 00:00:42,100

SUNK keeps large, long running

training jobs predictable at scale.

12

00:00:42,566 --> 00:00:45,033

The results speak for themselves.

13

00:00:45,033 --> 00:00:49,033

Topology-aware scheduling and tuned

infrastructure delivers

14

00:00:49,033 --> 00:00:52,033

better efficiency over

comparative benchmarks.

15

00:00:52,066 --> 00:00:54,766

Production-grade reliability

keeps long-running

16

00:00:54,766 --> 00:00:57,766

training productive,

even in the face of hardware events.

17

00:00:58,200 --> 00:00:59,866

And when failures do happen,

18

00:00:59,866 --> 00:01:05,300

automated self-healing and re-queuing

gets your training job back on track—fast.

19

00:01:05,300 --> 00:01:09,533

CoreWeave customers can create

training-ready sunk clusters using guided,

20

00:01:09,600 --> 00:01:12,733

opinionated, self-service.

Or work with solutions

21

00:01:12,733 --> 00:01:16,433

architects to design custom environments

for frontier-scale training.

22

00:01:16,800 --> 00:01:19,500

Either way, you'll be running the industry

standard

23

00:01:19,500 --> 00:01:22,733

for resilient, large-scale

AI training workloads.
