Revolutionize Your Chatbot Game with the Chat GPT API and Python — Get Started in Just 3 Minutes!
Chat GPT is a powerful tool that allows developers to build conversational agents and chatbots using natural language processing (NLP) and machine learning (ML). It uses a variant of the GPT (Generative Pre-trained Transformer) language model to generate responses to user inputs in a conversational context. In this blog, we will learn how to use the Chat GPT API with Python to build a simple chatbot.
Prerequisites:
- An OpenAI API key: You will need an OpenAI key to use the API. You can sign up for a free trial on the OpenAI website. Link to API keys here!
- Python 3: This tutorial is written in Python 3, so you will need to have Python 3 installed on your machine.
- The OpenAI library. You can install it using pip:
pip install openai
Setting up the environment:
First, let’s import the necessary libraries and set up the API key.
import openai
# Replace YOUR_API_KEY with your OpenAI API key
openai.api_key = "YOUR_API_KEY"
Sending a request to the API:
Now that we have our API key, we can start making requests to the API. We will use the openai.Completion.create()
function with the following parameters:
model_engine
: The name of the model you want to use. We will be using thetext-davinci-003
model for this tutorial. This is the most capable GPT-3 model. More info here. (Note that the latest Chat GPT model isn’t available yet via API)prompt
: The prompt or context for the conversation. This can be a single line of text or a multi-line prompt separated by newlines.max_tokens
: The maximum number of tokens (words and punctuation) to generate in the response. The minimum is 1 and the maximum is 2048.- And a few more parameters that you can use to tweak the answer.
Here’s an example of how to ask a question to the API:
# Set the model and prompt
model_engine = "text-davinci-003"
prompt = "Write a blog on ChatGPT"
# Set the maximum number of tokens to generate in the response
max_tokens = 1024
# Generate a response
completion = openai.Completion.create(
engine=model_engine,
prompt=prompt,
max_tokens=max_tokens,
temperature=0.5,
top_p=1,
frequency_penalty=0,
presence_penalty=0
)
# Print the response
print(completion.choices[0].text)
Response:
Now that we have the response from the API, we can parse it and use the generated response in a chatbot, website,…
PS you don’t have an unlimited amount free credits, think about that when building ;)
