## Which one, for what

### Lambda Cloud (D)

Good for: Agents or pipelines that need a whole GPU machine with SSH for hours, such as training or batch jobs, and will manage the lifecycle themselves.

Ahead on:
- Reliability, 50 against 20
- Agent ergonomics, 63 against 56

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

Watch for: No scale to zero, autoscaling or endpoints; an idle VM bills until terminated

### 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:
- Maintenance & community, 51 against 5

Also in its favour:
- Cheaper for gpu compute, $5.43 against $9.86 per GPU-hour

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

## Verdicts

**Lambda Cloud.** H100 SXM at $3.99 and B200 at $6.69 an hour with per-minute billing. No scale to zero, autoscaling or endpoints; an idle VM bills until terminated.

**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

### Lambda Cloud

1. Call `GET /instance-types` first and read `regions_with_capacity_available` before trying to launch
2. Space launch calls 12 seconds apart; a sixth in a minute returns 429 with `global/rate-limited`
3. Branch on the error `code`, not the `message` or `suggestion`, which Lambda says may change
4. List instances before retrying a failed launch, since there's no idempotency key and a retry can start a second machine
5. Terminate the instance in a `finally` block; billing runs by the minute until you do

### 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.
