      mannequin="gpt-4",
      messages=[{"role": "user", "content": "query"}]
  )
  print(chat_completion.selections[0].message.content material materials supplies)

Correct proper right here, shopper.chat.completions.create is a strategy title on the shopper object. The chat attribute accesses the chat-specific functionalities of the API, and completions.create is a technique that requests the AI mannequin to generate a response or completion based mostly completely on the enter supplied.

Change the question with the fast you want to run, and be at liberty to make the most of any supported GPT mannequin instead of the chosen GPT-4 above.

Dealing with errors

Whereas making requests, diversified components may happen, together with neighborhood connectivity factors, value restrict exceedances, or completely totally different non-standard response standing code. Subsequently, it’s important to care for these standing codes precisely. We’re able to make use of Python’s strive and other than blocks for sustaining program circulation and higher error dealing with:

strive:
    chat_completion = shopper.chat.completions.create(
        mannequin="gpt-4",
        messages=[{"role": "user", "content": "query"}],
        temperature=1,
        max_tokens=150  
    )
    print(chat_completion.selections[0].message.content material materials supplies)

other than openai.APIConnectionError as e:
    print("The server couldn't be reached")
    print(e.__cause__)

other than openai.RateLimitError as e:
    print("A 429 standing code was obtained; we should always at all times on a regular basis as soon as extra off a bit.")

other than openai.APIStatusError as e:
    print("One totally different non-200-range standing code was obtained")
    print(e.status_code)
    print(e.response)

Phrase: it is best to have obtainable credit score rating ranking grants to have the facility to utilize any mannequin of the OpenAI API. If larger than three months have handed since your account creation, your free credit score rating ranking grants have in all probability expired, and as well as you’ll can buy extra credit score rating (a minimal of $5).

Now listed under are some methods chances are high you will further configure your API requests:

• Max Tokens. Prohibit the utmost potential output dimension primarily based in your wishes by setting the max_tokens parameter. That’s usually a cost-saving measure, nonetheless do uncover that this merely cuts off the generated textual content material materials from going earlier the restrict, not making the general output shorter.
