### Code Example

```javascript theme={null}
response = arize_client.log(
  (model_id = "sample-model"),
  ...(environment = Environments.TRAINING)
);

response = arize_client.log(
  (model_id = "sample-model"),
  ...(environment = Environments.VALIDATION)
);

response = arize_client.log(
  (model_id = "sample-model"),
  ...(environment = Environments.PRODUCTION)
);

response = arize_client.log(
  (model_id = "sample-model"),
  ...(environment = Environments.CORPUS)
);
