CoreWeave
Direct-to-Expert

Build alongside the engineers who know what it takes to run AI at scale. From pilot through production, CoreWeave experts work directly with your team on what you’re building and what’s breaking, in the channels you’re already using.

Experience you don't have to build from scratch.

Bring CoreWeave engineers into your work - from the decisions you make before deployment to the challenges that only appear at scale.

Build with the builders

Reach production without losing time or absorbing the cost of every wrong turn. CoreWeave engineers make the architecture calls with your team, and surface wrong turns in a design review instead of several weeks into a build.

Straight to the fix

When compute is sitting idle, you need AI engineers working with you, not a best practices document. Post in the channel you already use and the issue goes directly to the CoreWeave expert who understands the failing layer. That expert stays with you through resolution.

Experience is the playbook

The hardest problems in AI don't have a troubleshooting guide yet. CoreWeave AI engineers have run clusters at frontier scale and worked through failures very few have seen. So when something breaks in a way you haven't seen before, odds are they have.

The right engineer. Right away.

AI moves too fast for every problem to come with a playbook. The workload behaves differently at 500 nodes than it did at eight. And when something breaks across compute, networking, storage, or software, the symptom rarely tells you where the problem lives.

CoreWeave Direct-to-Expert puts CoreWeave AI engineers alongside yours. The people who design, build, and operate the infrastructure work with you, from the first design review to production.

From pilot to production

Support through the whole lifecycle

The path from first design to production is full of decisions that are expensive to undo, and it's where most AI projects stall. CoreWeave Direct-to-Expert, included with CoreWeave infrastructure, is here for every step.

Plan and prove

Work through requirements, architecture, cluster sizing, and tradeoffs with engineers who know how those decisions behave at scale, then prove the design in production on CoreWeave ARENA.

Onboard and migrate

Provisioning capacity isn't the same as getting a workload running. CoreWeave engineers work on scheduler configuration, storage layout, and tuning for your specific workload with your team, so your first useful run happens sooner.

Build and solve

Whatever issue you hit, odds are a CoreWeave engineer has hit it before. And, when there isn't a reference architecture to copy, our engineers work with you to build what's missing and pressure-test it before it carries real weight.

Run and resolve

CoreWeave Mission Control sees down to the silicon and across every link between nodes. When something breaks, the engineer on your issue starts from live telemetry instead of a ticket description, and stays with it through resolution.

Expertise proven in practice

CoreWeave has worked this way since the first frontier models were trained on our clusters.

400+

proofs of concept run in CoreWeave ARENA

CoreWeave engineers have worked through workload shape, cluster sizing, and architecture tradeoffs across hundreds of customer POCs.

98%

Customer satisfaction

Direct-to-Expert operates at 98% CSAT across more than 1,200 issues per quarter.

Minutes

Until the right engineer responds

No chatbots, no automated responses. When you need a human expert, you get a human expert, in minutes.

ARENA PASS

Your path to ARENA

Work with CoreWeave experts to get real performance, cost, and operational evidence before you scale.‍

For most teams, a CoreWeave Direct-to-Expert engagement starts in CoreWeave ARENA. ARENA provides an end-to-end environment for evaluating real workloads on purpose-built, production-grade AI infrastructure and CoreWeave Forge, our connected developer platform. CoreWeave Direct-to-Expert support works with you to align on workload, prerequisites, and the success criteria you can use to evaluate outcomes.

To get started, request an ARENA Pass to get a guided evaluation. You request one, get qualified, and get matched with a CoreWeave expert who scopes the run around your workload.

Apply for your ARENA Pass
14 days free

Your ARENA Pass includes

Full access for 14 days

Dedicated time to evaluate your workload on CoreWeave.

Expanded inference credits

More inference credits than the standard trial.

CoreWeave infrastructure access

Including priority access to Vera Rubin.

CoreWeave Forge Enterprise

Qualified teams can continue with a 90-day Forge Enterprise trial.

ARENA is available by application only and is not a self-service trial.

What our customers are saying

Pioneers inventing AI at the frontier hit problems most teams have never seen. Here's what changes when a CoreWeave engineer is already on the problem with them.

"IBM's sandbox workloads weren't a fit for a standard capacity plan. CoreWeave engineers sat down with us early to shape the design and match it to our existing network and access setup. As we increased the volume and variety of traffic across our local hardware and burst into additional capacity on CoreWeave Sandboxes, we worked together to keep the customer experience seamless while still using our own hardware efficiently."
Brian Belgodere, Senior Technical Staff Member, IBM

“We train frontier models on CoreWeave, and at that scale the hard problems show up mid-run, when every restart costs us real time. What changed is who we talk to when that happens. We aren't filing a ticket and waiting for it to climb a queue. The CoreWeave engineer is already in the thread with us, knows our environment, and stays on the problem until we have the actual reason. That has saved us many hours of debugging and investigation on runs we couldn't afford to lose. It's less like vendor support and more like working with a dedicated teammate.”
Sam Braun, Member of Technical Staff, Cohere
