Side-by-side example
Here is a simple text completion example using the OpenAI API with the gpt-4o model.
import os
from openai import OpenAI
client = OpenAI(api_key=os.environ["OPENAI_API_KEY"])
response = client.chat.completions.create(
model="gpt-4o",
messages=[{"role": "user", "content": "Write a short poem about AI."}]
)
print(response.choices[0].message.content)AI weaves its silent art, In circuits deep, a beating heart. Learning, growing, day and night, A future bright with coded light.
Hugging Face equivalent
Using the Hugging Face Inference API with the gpt2 model for text generation.
import os
import requests
API_URL = "https://api-inference.huggingface.co/models/gpt2"
headers = {"Authorization": f"Bearer {os.environ['HF_API_KEY']}"}
payload = {"inputs": "Write a short poem about AI."}
response = requests.post(API_URL, headers=headers, json=payload)
print(response.json()[0]['generated_text'])Write a short poem about AI. Artificial intelligence is the future of technology, bringing new possibilities and challenges to the world.
