## 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.

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

### Which is better for AI agents, CoreWeave or Massed Compute?

CoreWeave scores 61.5 (C) on agent readiness against Massed Compute's 42.3 (E), and leads in 6 of 7 scored categories.
