Which one, for what

Baseten B

Good for Teams that want one model behind a production endpoint with real autoscaling knobs, environments and scoped keys.

Ahead on

  • Reliability, 80 against 20
  • Schema & documentation, 84 against 69
  • Security & auth, 82 against 61
  • Payments & pricing, 40 against 20
  • Maintenance & community, 90 against 51

Also in its favour

  • Open source

Watch for

H100 at $6.50 and A100 at $4.00 an hour, and start-up and idle replica time are billed

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

Baseten

Team API keys scoped to inference-only, metrics-only or a single environment or model, plus a Viewer role since 1 September 2026. H100 at $6.50 and A100 at $4.00 an hour, and start-up and idle replica time are billed.

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

Baseten

  1. Create a team key with inference-only permission for calling models and keep full-access keys out of the agent
  2. Sleep for retry_after seconds on a 429 from api.baseten.co; the activate and deactivate endpoints allow 20 calls a minute
  3. Retry 429, 503 and 529 with backoff, but treat 500 as a bug in your model code
  4. Set scale_down_delay below the 900-second default or every burst bills 15 idle minutes
  5. Send payloads over 256 KiB to /predict, not /async_predict, unless support has raised the async limit

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.
