On this tutorial, we’ll learn to arrange and use the OpenAI API for varied use instances. The tutorial is designed to be simple to observe, even for these with restricted data of Python programming. We’ll discover how anybody can generate responses and entry high-quality massive language fashions.
The OpenAI API permits builders to simply entry a variety of AI fashions developed by OpenAI. It gives a user-friendly interface that allows builders to include clever options powered by state-of-the-art OpenAI fashions into their functions. The API can be utilized for varied functions, together with textual content era, multi-turn chat, embeddings, transcription, translation, text-to-speech, picture understanding, and picture era. Moreover, the API is suitable with curl, Python, and Node.js.
To get began with OpenAI API, you first have to create an account on openai.com. Beforehand, each person was given free credit score, however now new customers are required to buy credit score.
To buy credit score, go to “Settings,” then “Billing,” and at last, “Add Fee Particulars.” Enter your debit or bank card info, and ensure to disable auto-recharge. Upon getting loaded 10 USD, you need to use it for a 12 months.
Let’s create the API key by navigating to “API keys” and choosing “Create new secret key”. Give it a reputation and click on on “Create secret key”.
Copy the API and create an Setting variable on the native machine.
I take advantage of Deepnote as my IDE. It is simple to create atmosphere variables. Merely go to “Integration”, choose “create atmosphere variable”, present a reputation and worth for the important thing, and create the mixing.
Subsequent, we’ll Set up the OpenAI Python bundle utilizing pip.
%pip set up --upgrade openai
We are going to now create a consumer that may entry varied varieties of fashions globally.
If in case you have set your atmosphere variable with the identify “OPENAI_API_KEY”, you need not present the OpenAI consumer with an API key.
from openai import OpenAI
consumer = OpenAI()
Please be aware that you need to solely present an API key if the identify of your atmosphere variable is totally different from the default one.
import os
from openai import OpenAI
consumer = OpenAI(
api_key=os.environ.get("SECRET_KEY"),
)
We are going to use a legacy perform to generate the response. The completion perform requires the mannequin identify, immediate, and different arguments to generate the reply.
completion = consumer.completions.create(
mannequin="gpt-3.5-turbo-instruct",
immediate="Write a brief story about Elon Musk being the largest troll.",
max_tokens=300,
temperature=0.7,
)
print(completion.selections[0].textual content)
The GPT3.5 mannequin have generate superb story about Elon Musk.
We will additionally stream our response by offering an additional argument `stream`.
As a substitute of ready for the entire response, the stream characteristic permits processing of output as quickly because it’s generated. This strategy helps to scale back perceived latency by returning the output of the language mannequin token by token moderately than .
stream = consumer.completions.create(
mannequin="gpt-3.5-turbo-instruct",
immediate="Write a Python code for accessing the REST API securely.",
max_tokens=300,
temperature=0.7,
stream = True
)
for chunk in stream:
print(chunk.selections[0].textual content, finish="")
The mannequin used API chat completion. Earlier than producing the response, let’s discover the out there fashions.
You possibly can view the checklist of all fashions out there or learn the Fashions web page on the official documentation.
print(consumer.fashions.checklist())
We are going to use the newest model of GPT-3.5 and supply it with a listing of a dictionary for system prompts and person messages. Make certain to observe the identical message sample.
completion = consumer.chat.completions.create(
mannequin="gpt-3.5-turbo-1106",
messages=[
{
"role": "system",
"content": "You are an experienced data scientist, adept at presenting complex data concepts with creativity.",
},
{
"role": "user",
"content": "What is Feature Engineering, and what are some common methods?",
},
],
)
print(completion.selections[0].message.content material)
As we are able to see, we have now generated an analogous end result because the legacy API. So, why use this API? Subsequent, we’ll study why the chat completion API is extra versatile and simpler to make use of.
Function engineering is the method of choosing, creating, or remodeling options (variables) in a dataset to enhance the efficiency of machine studying fashions. It entails figuring out essentially the most related and informative options and getting ready them for mannequin coaching. Efficient characteristic engineering can considerably improve the predictive energy of a mannequin and its capacity to generalize to new information.
Some frequent strategies of characteristic engineering embrace:
1. Imputation: Dealing with lacking values in options by filling them in with significant values such because the imply, median, or mode of the characteristic.

3. Normalization/Standardization: Scaling numerical options to deliver t.........
We are going to now learn to have a multi-turn dialog with our AI mannequin. To do that, we’ll add the assistant’s response to the earlier dialog and in addition embrace the brand new immediate in the identical message format. After that, we’ll present a listing of dictionaries to the chat completion perform.
chat=[
{"role": "system", "content": "You are an experienced data scientist, adept at presenting complex data concepts with creativity."},
{"role": "user", "content": "What is Feature Engineering, and what are some common methods?"}
]
chat.append({"position": "assistant", "content material": str(completion.selections[0].message.content material)})
chat.append({"position": "person", "content material": "Are you able to summarize it, please?"})
completion = consumer.chat.completions.create(
mannequin="gpt-3.5-turbo-1106",
messages=chat
)
print(completion.selections[0].message.content material)
The mannequin has understood the context and summarized the characteristic engineering for us.
Function engineering entails choosing, creating, or remodeling options in a dataset to reinforce the efficiency of machine studying fashions. Frequent strategies embrace dealing with lacking values, changing categorical variables, scaling numerical options, creating new options utilizing interactions and polynomials, choosing vital options, extracting time-series and textual options, aggregating info, and decreasing characteristic dimensionality. These methods intention to enhance the mannequin's predictive energy by refining and enriching the enter options.
To develop superior functions, we have to convert textual content into embeddings. These embeddings are used for similarity search, semantic search, and suggestion engines. We will generate embeddings by offering the API textual content and mannequin identify. It’s that easy.
textual content = "Information Engineering is a quickly rising discipline that focuses on the gathering, storage, processing, and evaluation of huge volumes of structured and unstructured information. It entails varied duties comparable to information extraction, transformation, loading (ETL), information modeling, database design, and optimization to make sure that information is accessible, correct, and related for decision-making functions."
DE_embeddings = consumer.embeddings.create(enter=textual content, mannequin="text-embedding-3-small")
print(chat_embeddings.information[0].embedding)

print(response.selections[0].message.content material)
The output completely clarify the picture.
That is a picture of an individual carrying numerous rice seedlings on a carrying pole. The person is sporting a conical hat, generally utilized in many components of Asia as safety from the solar and rain, and is strolling via what seems to be a flooded discipline or a moist space with lush vegetation within the background. The daylight filtering via the bushes creates a serene and considerably ethereal environment.
It is tough to find out the precise location from the picture alone, however such a scene is often present in rural areas of Southeast Asian nations like Vietnam, Thailand, Cambodia, or the Philippines, the place rice farming is a vital a part of the agricultural trade and panorama.
As a substitute of offering a picture URL, we are able to additionally load a neighborhood picture file and supply it to the chat completion API. To do that, we first have to obtain the picture by Manjeet Singh Yadav from pexels.com.
!curl -o /work/Information/indian.jpg "https://photographs.pexels.com/photographs/1162983/pexels-photo-1162983.jpeg?auto=compress&cs=tinysrgb&w=1260&h=750&dpr=2"
Then, we’ll load the picture and encode in base64 format.
import base64
def encode_image(image_path):
with open(image_path, "rb") as image_file:
return base64.b64encode(image_file.learn()).decode('utf-8')
image_path = "Information/indian.jpg"
# producing the base64 string
base64_image = encode_image(image_path)
As a substitute of offering the picture URL, we’ll present the metadata and the picture’s base64 string.
