## Which one, for what

### Koyeb (D)

Good for: Teams that want cheap H100 or H200 containers with scale to zero and an SLA, deployed from Git or an image without a vendor SDK.

Ahead on:
- Reliability, 60 against 20

Also in its favour:
- No incidents deducted, where Massed Compute loses 5 points for them

Watch for: Changelog silent since 27 February 2026 and no CLI release since 12 May 2026

### 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:
- Schema & documentation, 69 against 41
- Security & auth, 61 against 50
- Maintenance & community, 51 against 23

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

## Verdicts

**Koyeb.** H100 at $2.50 and H200 at $3.00 an hour, billed per second. Changelog silent since 27 February 2026 and no CLI release since 12 May 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

### Koyeb

1. Pass `dry_run` on service create or update to validate the definition before anything deploys
2. Page service lists with `limit` and `offset` and filter by `statuses` instead of fetching everything
3. Expect the first request after deep sleep to take 1 to 5 seconds and retry once with a timeout
4. Set `--min-scale 0` on GPU services so idle instances stop billing
5. Re-check the Mistral transition before building anything long-lived on it

### 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.
