CoreWeave
Infrastructure service
GPU cloud renting NVIDIA accelerators by the hour, with managed Kubernetes, storage and networking for training and inference.
Managed sandbox compute environments for AI development, billed as an add-on that varies with the buyer's base Weights & Biases plan tier ($10/mo on Free, $25/mo on Pro).
Modal
Infrastructure service
Serverless GPU compute: a Python decorator puts a function on an accelerator, scales it from zero to thousands of containers and stops billing when it stops running — aimed at inference, fine-tuning and batch jobs rather than reserved clusters.
Batch execution of large jobs across Modal's fleet, described as one line of code on the product page.
Serve, scale and optimise model inference on Modal's runtime, with sub-second cold starts and autoscaling across regions.
Isolated, instantly-started containers for running untrusted or agent-generated code at scale — the primitive behind AI app-generation products.
Managed training runs on Modal's fleet, configured in Python alongside the rest of a team's code.

CoreWeave sells these in a stack layer with no product recorded for Modal yet — nothing on the other side to compare them against.
AI agent
AI research agent built into the Weights & Biases platform that analyzes experiment data and production traces, forms hypotheses, designs and runs experiments, and generates dashboards and reports.
Platform
Operating layer for CoreWeave Cloud unifying security (IAM, compliance logging), fleet/node lifecycle automation with expert support, and observability (metrics, logs, telemetry), including an AI agent that answers questions about GPU performance and cluster health.
Modal sells these in a stack layer with no product recorded for CoreWeave yet — nothing on the other side to compare them against.
Developer tool
Hosted notebooks backed by Modal's GPUs, for profiling and experimenting without provisioning a machine.
