## 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:
- Agent ergonomics, 63 against 48
- Security & auth, 60 against 51

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

### Thunder Compute (C)

Good for: Agents in coding tools that rent a single persistent GPU machine for development, fine-tuning or a model server, at low hourly prices and over MCP.

Ahead on:
- Reliability, 65 against 50
- Maintenance & community, 79 against 5
- Transparency & trust, 64 against 58

Watch for: No rate limits, 429 guidance or SLA were found in the reviewed documentation, and the terms disclaim availability

## 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.

**Thunder Compute.** The hosted MCP server signs in with OAuth and separate read and write scopes, and the REST API has a public OpenAPI 3.1 document with keyless price and availability endpoints. No rate limits, SLA or API changelog were found, instance creation has no idempotency key, and instances cannot be stopped, only deleted.

## 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

### Thunder Compute

1. Call `GET /v2/status` or the `get_availability` tool before creating an instance. Availability can change before launch, and creation fails when a type is sold out.
2. List instances before retrying a failed create, because the call has no idempotency key.
3. Pass `public_key` on create. If omitted, the response carries a generated private key that is returned once.
4. To pause work, create a snapshot, delete the instance and later create a new instance from the snapshot. Snapshot storage keeps billing until deleted.
5. For headless use set `TNR_API_TOKEN` to a token from the console. The MCP server needs a browser sign-in on first connection.
