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.

Ahead on

  • Reliability, 50 against 20
  • Schema & documentation, 79 against 69
  • Security & auth, 74 against 61
  • Maintenance & community, 80 against 51
  • Transparency & trust, 77 against 61

Also in its favour

  • No incidents deducted, where Massed Compute loses 5 points for them

Watch for

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

Massed Compute E

Good for Agents that rent whole GPU VMs by the hour for training, fine-tuning or a model server and want a small MCP tool set with a read-only mode.

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

Watch for

No status page, incident history or security.txt was found on any of the vendor's hosts

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.

Massed Compute

The hosted MCP server and REST API accept OAuth grants or API tokens in read-only and full-access tiers, and all 17 tools carry typed schemas and safety annotations in a public server card. No status page, rate limit figures or API changelog were found, a launch has no idempotency key, and the governing terms could not be read.

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

Massed Compute

  1. Use https://vm.massedcompute.com/api/v1. The older docs at api-docs.massedcompute.com describe a separate marketplace API on api.massedcompute.com whose keys come from support.
  2. Ask the owner for a read-only token unless the task must launch or terminate. Read-only credentials cannot call launch, restart, terminate or SSH key changes.
  3. Call gpu_inventory_list and images_list before instances_launch. Product names and image IDs are free values, and SXM-only images do not run on PCIe cards.
  4. Expect 402 on launch until the owner has added credit and set a recharge amount and threshold. List instances before retrying a launch.
  5. Terminate to end billing. Stopping keeps the full hourly charge, and termination deletes the instance data.

Questions

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.
