Which one, for what

Cerebrium C

Good for Teams serving their own models as real-time endpoints (voice, LLM, image) who want per-second billing, multi-region placement and a scriptable management API.

Ahead on

  • Reliability, 48 against 20
  • Payments & pricing, 30 against 20
  • Maintenance & community, 75 against 51

Also in its favour

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

Watch for

disable_auth defaults to true, so a deployed endpoint answers without a token unless the owner changes it

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 49

Watch for

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

Verdicts

Cerebrium

Per-second GPU prices are public, a 94-operation OpenAPI spec covers the management API, and service account tokens expire and are limited to named projects. Deployed endpoints are callable without a token unless disable_auth = false is set, and no request rate limits, 429 handling or SLA 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

Cerebrium

  1. Set disable_auth = false in cerebrium.toml before deploying. The default leaves the endpoint callable by anyone with the URL
  2. Authenticate headless with CEREBRIUM_SERVICE_ACCOUNT_TOKEN. cerebrium login opens a browser
  3. Raise response_grace_period for long work. It defaults to 15 minutes and async runs stop at 12 hours
  4. Send ?async=true to get a run_id with HTTP 202, and add webhookEndpoint because async calls return no result to the caller
  5. Check the plan before choosing hardware. A100, H100, H200, B200 and RTX PRO 6000 need Standard, and protected compute bills at twice the listed rate

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.
