-            quality_preset (TLMQualityPreset): quality preset to use for TLM queries, which will determine the quality of the output responses and trustworthiness scores.
-            Supported presets include "best", "high", "medium", "low", "base".
-            The "best" and "high" presets will improve the LLM responses themselves, with "best" also returning the most reliable trustworthiness scores.
-            The "medium" and "low" presets will return standard LLM responses along with associated confidence scores,
-            with "medium" producing more reliable trustworthiness scores than low.
-            The "base" preset will not return any confidence score, just a standard LLM output response, this option is similar to using your favorite LLM API.
-            Higher presets have increased runtime and cost.
+            quality_preset (TLMQualityPreset): An optional preset to control the quality of TLM responses and trustworthiness scores vs. runtimes/costs.
+            TLMQualityPreset is a string specifying one of the supported presets: "best", "high", "medium", "low", "base".

+
+                Higher presets have increased runtime and cost (and may internally consume more tokens).

+                Avoid using "best" or "high" presets if you primarily want to get trustworthiness scores, and are less concerned with improving LLM responses.
+                These presets have higher runtime/cost and are optimized to return more accurate LLM outputs, but not necessarily more reliable trustworthiness scores.
 
             options (TLMOptions, optional): a typed dict of advanced configuration options.

-            verbose (bool, optional): whether to run in verbose mode, i.e., whether to show a tqdm progress bar when TLM is prompted with batches of data. If None, this will be determined automatically based on whether the code is running in an interactive environment such as a notebook.
