+|      metrics      | List for subset of metrics to be computed. All supported metrics listed below.                                   | list<str> | ["perplexities"]            |
+|     model_id      | Model used for calculating Perplexity. Perplexity can only be calculated for causal language models.             | str       | "gpt2", "bert-base-uncased" |

+|  add_start_token  | Boolean flag to add the start token to the texts so the perplexity can include the probability of the first word | boolean   | true, false                 |
+| custom_dimensions | Used to report telemetry data (can later be used to perform PII scrubbing)                                       | dict      |                             |
