How rentals work

You pay by the millisecond from verified readiness. A start that never gets ready is not charged.

The rental lifecycle

Pick and quote. Choose a model, template or pinned image on the Rent page.
Quote rules
Only offers whose measured GPU memory fits the template are selectable. The duration slider requests a server quote for every change. A quote is immutable, expires after 60 seconds and must be re-accepted if the price changes.
Fund and reserve. Reserving holds your budget and the machine in one step.
When two sessions race
Two sessions competing for one offer produce one allocation and an explicit conflict. The losing session's credit is never spent.
Verified start. The meter starts at verified readiness, not when the container exists.
Readiness check
Readiness is an external probe bound to your leased endpoint. For model templates it is an HTTP check of the template's readiness path (for example /health answering 200). A start that never reaches readiness fails with a named reason and is not charged.
Run. Connect over SSH and check the host-key fingerprint first.
Connection details
Default access is an SSH local forward to the supported Jupyter endpoint. Verify the host-key fingerprint shown on the rental page. There is no browser terminal.
```
ssh -L 8888:127.0.0.1:8888 -p <port> tenant@<edge-host>
# verify the host-key fingerprint shown on your rental page first
```
For models, amplerun tunnel <job> exposes the OpenAI-compatible endpoint on http://127.0.0.1:8000/v1. Add time without changing the agreed rate. Secrets, signed URLs and private keys never appear in logs.
Stop and retrieve. After a confirmed stop, results stay readable for 30 minutes.
Stop rules
Stop-requested and stop-confirmed are different states. Retrieval is over read-only SFTP; the GPU is off and the machine stays reserved for you until cleanup.
Settle. The final bill follows accepted meter evidence and the durable journal. Data erased at cleanup can't be recovered.

Trust vocabulary

Detected hardware, runtime, qualification and rentability are separate facts.
“Verified” always pairs a color cue with the word.
Unknown or missing evidence stays unavailable.

Money

Spendable, held, pending, disputed and withdrawable balances are shown separately.

Add funds from your account: USDC or USDT to your own deposit address on Base, or on any other network the Add-funds dialog lists. Agents can top up with x402. Your account shows the minimum and the exact networks. USD prices settle 1:1 in USDC under disclosed terms; see pricing for depeg risk.
