Which one, for what

CoreWeave C

Good for Teams that already run Kubernetes and need whole multi-GPU nodes or clusters for training and dedicated inference, with a contract and IAM.

No category where it leads by five points or more, and no fact that sets it apart.

Watch for

No self-serve route. CoreWeave's sales team approves an organisation and emails the activation link before a token can be created

Nebius AI Cloud B

Good for Teams that want whole GPU VMs or InfiniBand clusters in Europe, the UK, Israel or the US with IAM, Terraform and an SLA, and are content to manage endpoint lifecycles themselves.

Verdicts

CoreWeave

Per-hour prices for 8-GPU H100, H200 and B200 nodes are public, the docs ship as Markdown with llms.txt and embedded OpenAPI specs, and IAM has read-only roles per service. An organisation must be approved by CoreWeave's sales team before any token exists, and no request rate limits were found in the reviewed documentation.

Nebius AI Cloud

One API definition generates the REST and gRPC interfaces, the CLI, Terraform provider and three SDKs, with a 602-operation OpenAPI document, X-Idempotency-Key and role-scoped service accounts. The status page lists 14 major incidents between 14 July and 8 October 2026, no request rate limits were found, and signup needs a browser and a card.

Before you call either

CoreWeave

  1. Create an API access token at console.coreweave.com/tokens with an expiry and send it as Authorization: Bearer to https://api.coreweave.com
  2. Add GPUs by applying a NodePool resource (compute.coreweave.com/v1alpha1) to a CKS cluster with instanceType and targetNodes. instanceType can't be changed afterwards
  3. Set targetNodes to 0 or delete the Node Pool when a job ends. Nodes are whole 8-GPU machines billed by the hour
  4. Never pass dry_run to the MCP tool coreweave_kubectl_apply expecting a preview. The reference says the parameter is ignored and the manifest is applied
  5. Use a separate Forge API key and https://api.inference.wandb.ai/v1 for Serverless Inference. A CoreWeave API access token doesn't work there

Nebius AI Cloud

  1. Use a service account with an authorised key, then exchange a five-minute RS256 JWT at https://auth.eu.nebius.com/oauth2/token/exchange for a 12-hour Bearer token
  2. Send X-Idempotency-Key with a random UUID on every create, update and delete, since a 504 can follow a call that succeeded
  3. Poll the returned operation (/ai/v1/endpoints/operations/{id}) until status is set; concurrent operations on one resource are not supported
  4. Stop or delete endpoints when idle. A stopped endpoint bills nothing, a stopped Devlab or VM still bills for its disk
  5. Check region support first. Serverless AI is absent from eu-south1 and us-north1, and each GPU platform exists in one to four regions
  6. Run the beta nebius/mcp-server with safe mode on (the default); nebius_cli_execute can run any CLI command when SAFE_MODE=false

For companies

Do agents find, use and choose your tools?

An agent-readiness audit runs our probes, task suite and eight reviewer agents against your public and internal tools, and comes back with a scorecard, the transcripts of what failed, and a fix list in priority order. From $2,500, re-run included. We never take payment to move a rank. We do help companies earn one.
