model_api_key should be configurable

[ODAncona]

I would love to use another syntax than MODEL_API_KEY such as OPENAI_API_KEY="sk-proj-xxxxxxxx" like this model_client_options={"apiKey": os.getenv("OPENAI_API_KEY")},

However, the code check that MODEL_API_KEY is defined... Which prevents me to run it.

how about if you pass
model_api_key=os.getenv("OPENAI_API_KEY")
directly into the stagehand constructor?

[miguelg719]

does that solve it @ODAncona ?
