Introducing CoreWeave ARENA, New Lab for AI Production Readiness

LIVINGSTON, N.J.--(BUSINESS WIRE)--Feb 5, 2026--

CoreWeave, Inc. (Nasdaq: CRWV), The Essential Cloud for AI™, today announced CoreWeave ARENA (AI-Ready Native Applications), designed to help teams test workloads on purpose-built AI infrastructure and software that mirrors how AI actually runs in high-demand production settings. Replacing traditional sandbox or demo setups, the industry-leading CoreWeave ARENA pairs production-scale compute with a standardized evaluation environment.

As AI becomes part of day-to-day operations across industries, the integration from infrastructure to software determines ultimate success. Workloads are becoming more continuous and distributed, and performance or cost differences now matter more as everything from accelerators to agents evolve simultaneously. Organizations need earlier and more accurate insight into how their workloads will perform at scale, without the overhead of bespoke evaluation processes. CoreWeave ARENA provides a low-friction way to evaluate new workload performance through comprehensive, real-world benchmarking.

“Companies are now building products that have to perform in the real world, and quickly. But there’s been a gap between testing a model and actually running it at scale. CoreWeave ARENA closes that gap,” said Chen Goldberg, Senior Vice President, Engineering at CoreWeave. “We’re giving customers the tools and data they need to know exactly how their workloads will behave and what they will cost before they ever switch on production.”

For business and technology leaders across industries, CoreWeave ARENA offers a clearer way to understand whether an AI system is ready to run reliably at scale, before committing resources to teams, infrastructure, and operations.

“CoreWeave is providing an element of understanding and cost-certainty that was missing from the AI race, and is especially crucial for emerging companies,” said Dave McCarthy, research vice president, Cloud and Edge Services, Worldwide Infrastructure, IDC. “The inference stage, where models are actively processing live data and generating predictions, requires both compute power and intelligent system design for workloads to scale, and testing these ahead of production-altering decisions is key.”

Customers evaluating workloads through CoreWeave ARENA can trial the category-defining technologies that differentiate CoreWeave’s AI-native platform:

“Before committing to a full proof of concept, we wanted a clear view into how our workloads would actually perform, especially after seeing how much results can vary across providers,” said Xander Dunn, Member of Technical Staff, Periodic Labs. “Running our workloads on production-scale infrastructure gave us early, concrete insight into both performance and cost, which helped us evaluate next steps as we plan for scale, without slowing down execution.”

Customers are already starting to see the benefits:

Today’s announcement is part of CoreWeave’s broader platform strategy to unify the essential tools required to run AI at production scale on a single cloud platform, spanning high-performance compute, multi-cloud compatible data storage, and the software layer builders rely on to develop, test, and deploy AI systems. Recent platform innovations such as Serverless RL, the first publicly available, fully managed reinforcement learning capability, further extend this foundation. CoreWeave’s focus on performance and operational excellence is reflected in industry-leading MLPerf benchmark results and its distinction as the only AI cloud to earn top Platinum rankings in both SemiAnalysis ClusterMAX™ 1.0 and 2.0, reinforcing the company’s ability to deliver advanced AI infrastructure with reliability and efficiency at scale.

MILAN (AP) — Finland women’s hockey team’s preliminary round-opening game against Canada on Thursday has been postponed due to a stomach virus depleting Finland’s roster.

The game was rescheduled to Feb. 12.

The decision to postpone the game was announced shortly after Finland completed its early afternoon practice with just eight skaters and two goalies. The remaining 13 players are either in quarantine or isolation due to a norovirus that began affecting the team on Tuesday night.

The postponement provides Finland two extra days to rest before playing the U.S. on Saturday. Had their game against Canada not been postponed, Finnish officials were considering the possibility of a forfeiture.

“While all stakeholders recognize the disappointment of not playing the game as originally scheduled, this was a responsible and necessary decision that reflects the spirit of the Olympic Games and the integrity of the competition,” Olympic officials announced.

“All stakeholders thank teams, partners and fans for their cooperation and understanding, and look forward to the rescheduled game being played under safe and appropriate conditions.”

Team Finland officials were already weighing the likelihood of not playing before the game was postponed.

Coach Tero Lehterä said it could be unfair to ask his 10 currently healthy players to compete in a full game. Lehterä also said the team has to take into account the possibility of Canadian opponents being infected as well.

“Most of them are getting better but not healthy enough to play. And there’s the chance that if we would play it could influence Team Canada and their health as well,” Lehterä said following practice.

“But I couldn’t risk my players if they were ill yesterday to play tonight because that would be wrong against the individual,” he added.

Lehterä said the first sign of the illness became apparent on Tuesday night — and after the team held a full practice earlier in the day.

The rescheduled game falls on the second of two consecutive off days during the women’s tournament, and a day before the quarterfinals open.
