openai.ChatCompletion.create(

model=”gpt-3.5-turbo”,

messages=[

“role”: “system”, “content”: “You are a helpful assistant.”,

“role”: “user”, “content”: “Who won the world series in 2020?”,

“role”: “assistant”, “content”: “The Los Angeles Dodgers won the World Series in 2020.”,

“role”: “user”, “content”: “Where was it played?”

]

)

After sending the messages, you’ll receive a response from the API, which includes the assistant’s reply in the ‘choices’ field.

4. Handling API Responses

The response from the API will contain the assistant’s reply in the ‘choices’ field. You can extract the assistant’s reply from the response using:

response[‘choices’][0][‘message’][‘content’]

It’s important to note that the response may also include other fields like ‘id’, ‘object’, ‘created’, ‘model’, ‘usage’, etc., which provide additional information about the API call and usage details.

5. Iterative Chatting

To have a dynamic conversation with the assistant, you can simply extend the array of messages and continue the back-and-forth interaction. The assistant will remember the conversation history and provide contextual responses.

Here’s an example of extending the conversation:

openai.ChatCompletion.create(

model=”gpt-3.5-turbo”,

messages=[

“role”: “system”, “content”: “You are a helpful assistant.”,

“role”: “user”, “content”: “Who won the world series in 2020?”,

“role”: “assistant”, “content”: “The Los Angeles Dodgers won the World Series in 2020.”,

“role”: “user”, “content”: “Where was it played?”,

“role”: “assistant”, “content”: “The World Series in 2020 was played in Arlington, Texas at the Globe Life Field, which was the new home stadium for the Texas Rangers.”

]

)

By extending the conversation, you can create more interactive and dynamic chat-based applications.

6. API Cost and Usage

Using the ChatGPT API has associated costs. You will be billed per token, where both input and output tokens count towards the total. You can check the ‘usage’ field in the API response to see the number of tokens used.
