The model outputs speech natively at 44kHz.

You can use cURL or any other http client to run inferences:

```bash
curl -X POST \
    -d '{"text": "The quick brown fox jumps over the lazy dog"}'  \
    -H "Authorization: bearer $DEEPINFRA_TOKEN"  \
    -H 'Content-Type: application/json'  \
    'https://api.deepinfra.com/v1/inference/Zyphra/Zonos-v0.1-transformer'
```

which will give you back something similar to:

```json
{
  "audio": null,
  "input_character_length": 0,
  "output_format": "",
  "request_id": null,
  "inference_status": {
    "status": "unknown",
    "runtime_ms": 0,
    "cost": 0.0,
    "tokens_generated": 0,
    "tokens_input": 0
  }
}

```


You can use our command-line tool [deepctl](/docs/advanced/deepctl) to run
inferences:

```bash
deepctl infer \
    -m 'Zyphra/Zonos-v0.1-transformer'  \
    -i 'text=The quick brown fox jumps over the lazy dog'
```

which will give you back something similar to:

```json
{
  "audio": null,
  "input_character_length": 0,
  "output_format": "",
  "request_id": null,
  "inference_status": {
    "status": "unknown",
