Specifying model: "gpt-4" isn't working

[bzorn]

Previously, I was able to say model: "gpt-4" and the code would infer I meant "openai:gpt-4"
Now, when I say model: "gpt-4" I get an error message saying model not found.
Either docs or code should be updated.

script({ title: "test1", 
    model: "gpt-4", 
    group: "text", 
    system: ["system"]})
