Which one, for what

Crusoe Cloud B

Good for Teams that want whole GPU machines or clusters with managed Kubernetes or Slurm in the US, Iceland or Norway, under an SLA, and are content to manage lifecycles themselves.

Ahead on

  • Reliability, 66 against 20
  • Schema & documentation, 79 against 69
  • Security & auth, 74 against 61
  • Payments & pricing, 30 against 20
  • Maintenance & community, 76 against 51
  • Transparency & trust, 77 against 61

Also in its favour

  • Runs on your own machine
  • No incidents deducted, where Massed Compute loses 5 points for them

Watch for

No idempotency key or safe-retry guidance was found for create and delete calls, which return asynchronous operations to poll.

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.

Ahead on

  • Agent ergonomics, 56 against 45

Watch for

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

Verdicts

Crusoe Cloud

The v1 REST API has a published OpenAPI description, Markdown docs, HMAC-signed keys, reader roles and a 90-day audit log, with on-demand GPU prices public. No idempotency keys or control-plane rate limits were found, spot and B200 prices go through sales, and a storage outage in eu-norway1 lasted about four hours on 29 September 2026.

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

Crusoe Cloud

  1. Sign every request. Build the payload from path, sorted query string, verb and X-Crusoe-Timestamp, HMAC-SHA256 it with the base64url-decoded secret, and send Authorization: Bearer 1.0:<access_key_id>:<signature>.
  2. Use https://api.cloud.crusoe.ai/v1. Some docs pages and the MCP server still name api.crusoecloud.com and /v1alpha5.
  3. Creates, updates and deletes return an operation. Poll the matching operations endpoint for state, and list existing resources by name before retrying a create, because no idempotency key was found.
  4. Managed AI uses separate Intelligence API keys and hosts, api.inference.crusoecloud.com for OpenAI-compatible calls and api.intelligence.crusoecloud.com for files and fine-tuning jobs.
  5. Delete a VM and its disks to stop charges. A stopped on-demand VM is not billed for compute, but its 128 GB OS disk still bills at $0.08 a GiB-month.

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.

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.
