Why I cannot set engine to "gpt-4" during my usage

[xuantianfengwu]

I found the engines in the file of "V3.py" has "gpt-4", thus I try to set the engine as "gpt-4" during my usage.

But then, I will meet 404 web request problem:
APIConnectionError: 404 Not Found {
"error": {
"message": "The model: gpt-4 does not exist",
"type": "invalid_request_error",
"param": null,
"code": "model_not_found"
}
}

Is there any explanation for the result? Why OpenAI returns a 404 for "gpt-4"?

print("Supported engines: ", ", ".join(tiktoken.model.MODEL_TO_ENCODING)) returns

Supported engines: gpt-4, gpt-3.5-turbo, text-davinci-003, text-davinci-002, text-davinci-001, text-curie-001, text-babbage-001, text-ada-001, davinci, curie, babbage, ada, code-davinci-002, code-davinci-001, code-cushman-002, code-cushman-001, davinci-codex, cushman-codex, text-davinci-edit-001, code-davinci-edit-001, text-embedding-ada-002, text-similarity-davinci-001, text-similarity-curie-001, text-similarity-babbage-001, text-similarity-ada-001, text-search-davinci-doc-001, text-search-curie-doc-001, text-search-babbage-doc-001, text-search-ada-doc-001, code-search-babbage-code-001, code-search-ada-code-001, gpt2.

It seems that any engine input (regardless of implementation) by the user returns a NotImplemented error?

    def get_token_count(self, convo_id: str = "default") -> int:
        """
        Get token count
        """
        if self.engine not in ENGINES:
            raise NotImplementedError(f"Unsupported engine {self.engine}")

        tiktoken.model.MODEL_TO_ENCODING["gpt-4"] = "cl100k_base"

        encoding = tiktoken.encoding_for_model(self.engine)

        num_tokens = 0
        for message in self.conversation[convo_id]:
            # every message follows <im_start>{role/name}\n{content}<im_end>\n
            num_tokens += 5
            for key, value in message.items():
                num_tokens += len(encoding.encode(value))
                if key == "name":  # if there's a name, the role is omitted
                    num_tokens += 5  # role is always required and always 1 token
        num_tokens += 5  # every reply is primed with <im_start>assistant
        return num_tokens

Your account doesn't have access to gpt-4. You need to apply on a waitlist
