I'm using the updated OpenAI SDK with GPT-4 and encountering the following error when generating an improved tag title:
PYTHONError occured while calling OpenAI API: Missing required arguments; Expected either ('model' and 'prompt') or ('model', 'prompt' and 'stream') arguments to be given
The code below shows my implementation. I'm using the completions endpoint with a parameter structure meant for the chat completions method:
PYTHON# ottieni tag title da gpt ################################# #import openai from dotenv import load_dotenv import os load_dotenv() # Carica le variabili d'ambiente dal file .env #openai.api_key = os.getenv("openai.api_key") # new from openai import OpenAI client = OpenAI(api_key=os.environ['openai.api_key']) # setup richiesta gtp # nuovo dataframe merged_df8b = merged_df8.copy() # creo dizionario delle risposte di gpt per evitare chiamate doppie gpt_responses = {} # Inizializza un contatore per il numero totale di token total_tokens_used = 0 # Inizializza un contatore per le chiamate API effettive actual_api_calls = 0 def improve_tag_title(row, gpt_responses): global total_tokens_used, actual_api_calls top_5_queries = row['top_5_queries'] # Ottieni il tag title e l'URL dalla riga corrente tag_title = row["tag title"] page_url = row["page"] # Controllo se tag_title è presente e non vuoto if not tag_title: return None # Verifica se l'URL è già stato processato if page_url in gpt_responses: return gpt_responses[page_url] # Usa il tag title migliorato se disponibile prompt = ( f"Sto cercando di migliorare il tag title per una pagina web. Il tag title attuale è: {tag_title}.\n" f"Le parole chiave più importanti e pertinenti alla pagina sono: {top_5_queries}.\n" f"Crea un nuovo tag title in {language} che incorpori queste parole chiave in modo naturale e coinvolgente. Il tag title dovrebbe:\n" f"1) avere al massimo 65 caratteri, spazi inclusi. Assicurati che la tua risposta non superi questo limite.\n" f"2) non includere il nome del brand.\n" f"3) non utilizzare lettere maiuscole inutili, simboli, apici o virgolette.\n" f"4) essere presentato da solo, senza alcuna spiegazione o contenuto aggiuntivo.\n" f"Per favore, segui scrupolosamente tutte queste regole nella tua risposta. Se non sei sicuro, conferma che hai seguito tutte le regole nel tuo messaggio." ) try: response = client.completions.create( model="gpt-4", messages=[ {"role": "system", "content": "Comportati come se fossi un SEO copywriter professionista."}, {"role": "user", "content": prompt} ], max_tokens=1000, temperature=0.4, top_p=1, frequency_penalty=0.1, presence_penalty=0.1 ) total_tokens_used += response['usage']['total_tokens'] actual_api_calls += 1 except Exception as e: print(f"Error occured while calling OpenAI API: {e}") return None improved_tag_title = response.choices[0].message.content.strip().lower() gpt_responses[page_url] = improved_tag_title time.sleep(1) return improved_tag_title
I also experimented with renaming the parameter from messages to prompt and then received this error:
PYTHONError occured while calling OpenAI API: Error code: 404 - {'error': {'message': 'This is a chat model and not supported in the v1/completions endpoint. Did you mean to use v1/chat/completions?','type': 'invalid_request_error','param': 'model','code': None}}
Based on the error message and the accepted answer, it seems that the issue is due to calling the completions endpoint with parameters intended for the chat completions endpoint. Chat models such as "gpt-4" require using the chat endpoint and the messages parameter. How can I modify my code to correctly call the appropriate endpoint using the updated SDK?
Thanks in advance!

The error occurs because you're using the completions endpoint (client.completions.create) with parameters intended for the chat completions endpoint. Chat models like "gpt-4" require you to call the chat completions endpoint with the "messages" parameter, not the "prompt" parameter.
When you try changing "messages" to "prompt", the request goes to an endpoint that doesn't support chat models, hence the 404 error.
To fix the issue, use the chat completions endpoint. For example:
PYTHONresponse = client.chat.completions.create( model="gpt-4", messages=[ {"role": "system", "content": "Comportati come se fossi un SEO copywriter professionista."}, {"role": "user", "content": prompt} ], max_tokens=1000, temperature=0.4, top_p=1, frequency_penalty=0.1, presence_penalty=0.1 )
This ensures you're calling the correct endpoint for chat models and passing the required "messages" argument.
