Can not switch to gpt-4

[bidcrt]

Greeting,
I have tried to use usethis::edit_r_environ() and add OPENAI_MODEL="gpt-4," but it does not work for me to switch to gpt-4. Am I right on that?
Thanks.

Hi @bidcrt , I am not sure how setting env vars is managed by usethis.
To change the used model I would simply put this at the very first of my scripts: Sys.setenv(OPENAI_MODEL = "gpt-4").
Or I would add OPENAI_MODEL="gpt-4" at my ~/.Renviron file.

To test that the env var is correctly set, you can try if it errors on non existing models:

 Sys.setenv(OPENAI_MODEL = "FAKE_MODEL")
> chatgpt::ask_chatgpt("In 4 words describe the R language.")
Error in gpt_get_completions(question, messages = chat_session_messages) :
list(message = "The model `FAKE_MODEL` does not exist or you do not have access to it.", type = "invalid_request_error", param = NULL, code = "model_not_found")
> Sys.setenv(OPENAI_MODEL = "gpt-4")
> chatgpt::ask_chatgpt("In 4 words describe the R language.")
