Modal Sandboxes plans an Arm-based mixed fleet with NVIDIA Vera
Modal plans to add Vera CPU support for agent and reinforcement-learning workloads; its early tests report up to twice the task throughput under heavy contention.
AT A GLANCE
Key points
- Modal plans its first Arm-based expansion beyond an all-x86 fleet
- Provider reports up to 2x task throughput under concurrent load
- Mixed fleet will continue to include Intel and AMD systems
- Results are early provider benchmarks, not independent production tests
What is changing?
Modal said on October 19 that it plans to add NVIDIA Vera CPU support to its Sandboxes service. The Arm-compatible processor would be the first architectural expansion of an infrastructure that has so far relied on x86 servers from Intel and AMD. Modal says the move requires changes across its infrastructure and image-build system.
The company tested compilation, file search, Git operations, device emulation and other agent tasks using Agentless Agent Bench, derived from 50 Terminal-Bench solutions and verifiers. In Modal’s early results, Vera delivered up to twice the task throughput of an equivalent x86 GNR machine under heavy concurrency, although it was not always the fastest option for individual tasks.
Reuters reports that Modal is not abandoning Intel or AMD; it plans a mixed fleet that routes work to the hardware that performs best. That distinction matters: the results come from Modal’s own early testing, and independent production measurements against newer x86 generations have not yet been published.
