-// LocalAI is based on OpenAI (async-openai), because it seems to be fully compatible.
-// Moreover, openai_api_rust does not support speech-to-text, so if we wish to use this feature

+// At the time of testing, LocalAI can be powered by `openai`, but we use `openai_compat` for better reliability
+// in the event of future updates to `async-openai`.
