ai.batch-create-request@1: the body of POST /api/v1/batches on OpenVibe.AI (capability ai.batches.create). One batch of many prompts: the answers come later, and the batch is billed at half the retail price. Errors are problem+json: 422 input.invalid (no items, an empty prompt, a prompt over 20000 characters, a deadline outside 1 to 72 hours), 422 batch.too\_large (more prompts than the service's cap), 403 batch.no\_payer (the token names no account to pay), 403 batch.no\_grant (a service without the ai.batches.create grant).

## Fields

| Field | Type | Required | Description | Constraints |
| --- | --- | --- | --- | --- |
| `items` | array of one of | yes | The prompts of the batch, in order. Each item is a prompt, or an object with a prompt and the model it wants. | - `minItems 1` |
| `model` | string |  | The model the whole batch asks for, when no item names one. |  |
| `deadline_hours` | integer |  | How long the batch may take, in hours (1 to 72). Omitted: the service's own default (24 hours). A prompt that reaches the deadline without cheap capacity expires and is never charged. | - `minimum 1`<br>- `maximum 72` |
