First, you should [create service account](https://cloud.yandex.com/en/docs/iam/operations/sa/create) with the `ai.languageModels.user` role.

Next, you have two authentication options:

*   [IAM token](https://cloud.yandex.com/en/docs/iam/operations/iam-token/create-for-sa). You can specify the token in a constructor parameter `iam_token` or in an environment variable `YC_IAM_TOKEN`.
*   [API key](https://cloud.yandex.com/en/docs/iam/operations/api-key/create) You can specify the key in a constructor parameter `api_key` or in an environment variable `YC_API_KEY`.
