 Config values are applied in the following order of precedence (from highest to lowest):
 
 1. Values explicitly set in the `config` object/dictionary
-2. Environment variables (e.g., `OPENAI_API_KEY`, `OPENAI_API_BASE`)
+2. Environment variables (e.g., `OPENAI_API_KEY`, `OPENAI_BASE_URL`)
 3. Default values defined in the LLM implementation
 
 This means that values specified in the `config` will override corresponding environment variables, which in turn override default values.
