Queue a forward-backward pass

Request

  • Base URL
    https://api.fastino.ai
  • Auth
    • API key in header X-API-Key
    • or HTTP bearer

Path parameters

job_idstring required

Headers

Idempotency-Keystring nullable

Client-generated key (a UUID is ideal; it must be URL-safe to look it up) that makes the call safe to send again after a lost response. A repeat with the same key and body from the same caller returns the first call's answer (the same job and future) without running or billing it again, or a 409 while the first call still runs; the same key with another route, job, body or caller is a 422. Look a key up with GET /v1/training/operations/{idempotency_key}.

Request body

loss_fnstring

cross_entropy, importance_sampling, ppo, cispo or dro.

loss_fn_configobject nullable

Response

Successful Response

future_idstring required
