# Embeddings - Workflow node | Docs - nodulz

Source: https://nodulz.com/docs/nodes/ai_embeddings

Language: en

Create vector embeddings

## Usage and specifics

The provider and model must support embeddings. Output contains vectors, texts and model. Use dimensions compatible with the destination vector store.

Technical type : `ai_embeddings`. Runtime : `nodulz`.

## Credentials and prerequisites

- [Create and configure the credential : ai-model](/docs/credentials/ai-model)

Create credentials in your nodulz instance’s Credentials area, then select them on the node. Availability depends on ownership and sharing. See the [credentials guide](/docs/credentials) for access and rotation.

## Parameters

Names below are technical keys. Defaults are not a ready-to-run configuration: complete fields required by your operation. Paths containing [] describe list items; some fields depend on the selected mode.

| Parameter | Type | Default | Values / limits |
| --- | --- | --- | --- |
| `credentialId` | `string` | - | - |
| `model` | `string` | `"text-embedding-3-small"` | - |
| `input` | `string` | `""` | - |
| `inputSource` | `string` | `""` | - |
| `inputType` | `enum` | `"document"` | `document`, `query` |
| `batchSize` | `number` | `64` | -; ≥ 1, ≤ 128 |
| `maxBatchCharacters` | `number` | `24000` | -; ≥ 1, ≤ 1000000 |

## Initial configuration

Initial catalog configuration example, to adapt before running. Keep secrets in credentials.

```json
{
  "model": "text-embedding-3-small",
  "input": "",
  "inputSource": "",
  "inputType": "document",
  "batchSize": 64,
  "maxBatchCharacters": 24000
}
```

## Verification

Test with representative data. Check node output in the inspector and logs, then use editor mapping for downstream fields. A trigger test with a simulated payload does not validate external service delivery.
