proofs of concept run in CoreWeave ARENA
CoreWeave engineers have worked through workload shape, cluster sizing, and architecture tradeoffs across hundreds of customer POCs.
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.

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

CoreWeave has worked this way since the first frontier models were trained on our clusters.
CoreWeave engineers have worked through workload shape, cluster sizing, and architecture tradeoffs across hundreds of customer POCs.
Direct-to-Expert operates at 98% CSAT across more than 1,200 issues per quarter.
No chatbots, no automated responses. When you need a human expert, you get a human expert, in minutes.
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.
Dedicated time to evaluate your workload on CoreWeave.
More inference credits than the standard trial.
Including priority access to Vera Rubin.
Qualified teams can continue with a 90-day Forge Enterprise trial.
ARENA is available by application only and is not a self-service trial.
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.
CoreWeave Direct-to-Expert provides AI engineering support through our engineer-to-engineer partnership model. It gives your team direct access to CoreWeave experts who work alongside you on architecture, pilots, onboarding, migration, production workloads, and technical issues.
CoreWeave Direct-to-Expert starts before production and continues through your partnership with us. CoreWeave AI engineers can work with your team during evaluation and pilots, through onboarding and migration, and once workloads are running in production.
Depending on what you’re building or troubleshooting, you may work with CoreWeave product engineers, field engineers, ML researchers and engineers, or technical support engineers. When an issue requires deeper expertise, the appropriate product or field engineers are brought directly into the work.
Technical Support Engineers are the first responders for customer issues and bring in the appropriate product or field engineers when escalation is needed. Work happens through existing channels such as Slack, Microsoft Teams, and email, helping your team get to the right expertise without navigating a traditional tiered support queue.
CoreWeave Direct-to-Expert can help with architecture decisions, workload configuration, cluster sizing, onboarding and migration, custom builds, and production troubleshooting. CoreWeave experts can also help diagnose issues that cross infrastructure layers, where a problem in networking, storage, compute, or another service may surface somewhere else in the stack.
CoreWeave ARENA is a guided evaluation environment where you prove your own workload on CoreWeave infrastructure and Forge before you commit to anything. You benchmark the newest hardware, run your models, agents, and applications through the connected platform, and through CoreWeave Direct-to-Expert, work alongside CoreWeave engineers to see performance, cost, and what it would take to reach production. It's evidence from your own code, not a vendor benchmark or a pricing sheet.
CoreWeave ARENA Pass opens the program to qualified new teams. We prioritize mission-critical workloads such as production inference, agentic systems, RL post-training, and fine-tuning, from teams heading to production in the next 3 to 6 months.
Start with a CoreWeave Forge plan. CoreWeave Forge brings the whole improvement loop into one place, so you can run, observe, curate, improve, and evaluate your model or agent on the clouds and frameworks you already use. When your workload is heading to production in the next 3 to 6 months, apply for CoreWeave ARENA Pass and bring what you've built to test it in a full production environment.

Whether you’re proving an architecture, bringing a new workload online, scaling into production, or debugging something you haven’t seen before, you don’t have to build alone.
Work directly with CoreWeave engineers who have been there before—and are ready to build what comes next with you.
