# Retries and failures

Failed or uncertain inference refunds its reservation. Crash holds stay pending
until their finite deadline, then expire on access. A late completion cannot
charge an expired request. An admitted request keeps running if your client
disconnects, and completed work is charged even when its response cannot be
delivered; it cannot be downloaded later. Settlement follows the response, so
headers and JSON report reserved credit, while usage history is final.

Audio, transcripts and synthesis text are transient. There is no result replay,
job polling or download store. After an ambiguous failure, a fresh submission is
a new request and may consume compute and credit again.

Errors use `error.code`, `message`, `request_id` and `retryable`. Only safe
pre-admission capacity rejections advertise retryability. `402` indicates credit,
`422` invalid/unsupported input and `503` service failure.
Charges and pack allowances are described under [credits and packs](/docs/credits).
