## Things to keep in mind when using the API

### Model name format

The model name format today is model:tag`. Some examples are `orca:3b-q4_1` and `llama2:70b`. The tag is optional and if not provided will default to `latest`. The tag is used to identify a specific version.

### Durations

All durations are in nanoseconds.

## Generate a Prompt

**POST /api/generate**

### Description

**Generate** is the main endpoint that you will use when working with Ollama. This is used to generate a response to a prompt sent to a model. This is a streaming endpoint, so will be a series of responses. The final response will include the context and what is usually seen in the output from verbose mode.

### Request

The **Generate** endpoint takes a JSON object with the following fields:

```JSON
{
  "model": "site/namespace/model:tag",
  "prompt": "You are a software engineer working on building docs for Ollama.",
  "options": {
    "temperature": 0.7,
  }
}
```

**Options** can include any of the parameters listed in the [Modelfile](./modelfile.mdvalid-parameters-and-values) documentation. The only required parameter is **model**. If no **prompt** is provided, the model will generate a response to an empty prompt. If no **options** are provided, the model will use the default options from the Modelfile of the parent model.

### Response

The response is a stream of JSON objects with the following fields:

```JSON
{
  "model": "modelname",
  "created_at": "2023-08-04T08:52:19.385406455-07:00"
  "response": "the current token",
  "done": false
}
```

The final response in the stream also includes the context and what is usually seen in the output from verbose mode. For example:

```JSON
{
  "model":"orca",
  "created_at":"2023-08-04T19:22:45.499127Z",
  "done":true,
  "total_duration":5589157167,
  "load_duration":3013701500,
  "sample_count":114,
  "sample_duration":81442000,
  "prompt_eval_count":46,
  "prompt_eval_duration":1160282000,
  "eval_count":113,
  "eval_duration":1325948000
}
```
