Which one, for what

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

  • Security & auth, 61 against 40

Watch for

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

Replicate Deployments B

Good for Teams already calling Replicate's public models who want their own model behind the same API, MCP server and webhooks.

Ahead on

  • Reliability, 75 against 20
  • Schema & documentation, 85 against 69
  • Agent ergonomics, 68 against 56
  • Payments & pricing, 30 against 20
  • Maintenance & community, 70 against 51
  • Transparency & trust, 78 against 61

Also in its favour

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

Watch for

Private instances bill set-up and idle time, H100 at $5.49 an hour

Verdicts

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.

Replicate Deployments

OpenAPI file, llms.txt and an MCP server with a two-tool code mode. Private instances bill set-up and idle time, H100 at $5.49 an hour.

Before you call either

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.

Replicate Deployments

  1. List GET /v1/hardware first and use the returned sku in the deployment body
  2. Set min_instances to 0 for bursty work; a warm H100 bills $5.49 an hour whether called or not
  3. Send Prefer: wait on deployment predictions to block instead of polling
  4. Copy outputs within an hour; API prediction data is deleted after that
  5. Wait for the reset time in the 429 body before retrying; prediction creates cap at 600 a minute

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.
