Code updated for the latest Openai version

Hi, I updated the code, Completion was giving me an error, this code is working at this moment, just in case you come across the same issue:

from openai import OpenAI
client = OpenAI(
    api_key=api_key)
def generate_text(prompt):
    response = client.chat.completions.create(
        model="gpt-4o",
        messages=[
            {
            "role": "user",
            "content": prompt,
            }
        ],
        max_tokens=10,
        temperature=0.7)
    return response.choices[0].message.content
