"""
|
|
Starts a processing flow using a defined flow class.
|
|
|
|
Parameters can be provided in three ways:
|
|
1. As key=value pairs: --param model=gpt-4 --param temp=0.7
|
|
2. As JSON string: -p '{"model": "gpt-4", "temp": 0.7}'
|
|
3. As JSON file: --parameters-file params.json
|
|
|
|
Note: All parameter values are stored as strings internally, regardless of their
|
|
input format. Numbers and booleans will be converted to string representation.
