Invokes the LLM prompt service by specifying the prompt template to use
|
|
and values for the variables in the prompt template. The
|
|
prompt template is identified by its template identifier e.g.
|
|
question, extract-definitions. Template variable values are specified
|
|
using key=value arguments on the command line, and these replace
|
|
{{key}} placeholders in the template.
