## Which one, for what

### Cerebrium (C)

Good for: Teams serving their own models as real-time endpoints (voice, LLM, image) who want per-second billing, multi-region placement and a scriptable management API.

Ahead on:
- Schema & documentation, 70 against 41
- Security & auth, 60 against 50
- Payments & pricing, 30 against 20
- Maintenance & community, 75 against 23

Watch for: `disable_auth` defaults to true, so a deployed endpoint answers without a token unless the owner changes it

### 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 48
- Agent ergonomics, 56 against 49

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

## Verdicts

**Cerebrium.** Per-second GPU prices are public, a 94-operation OpenAPI spec covers the management API, and service account tokens expire and are limited to named projects. Deployed endpoints are callable without a token unless `disable_auth = false` is set, and no request rate limits, 429 handling or SLA were found in the reviewed documentation.

**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.

## Before you call either

### Cerebrium

1. Set `disable_auth = false` in `cerebrium.toml` before deploying. The default leaves the endpoint callable by anyone with the URL
2. Authenticate headless with `CEREBRIUM_SERVICE_ACCOUNT_TOKEN`. `cerebrium login` opens a browser
3. Raise `response_grace_period` for long work. It defaults to 15 minutes and async runs stop at 12 hours
4. Send `?async=true` to get a `run_id` with HTTP 202, and add `webhookEndpoint` because async calls return no result to the caller
5. Check the plan before choosing hardware. A100, H100, H200, B200 and RTX PRO 6000 need Standard, and `protected` compute bills at twice the listed rate

### 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
