​
Quick Start: Chat Completions

Jump right in with a simple Python example that sends prompts to a GPT model and prints the responses.
Ensure your OPENAI_API_KEY is exported as an environment variable before running these examples.
from openai import OpenAI

client = OpenAI(OPENAI_API_KEY)

prompts = [
    "Tell me a story about a brave knight",
    "Generate a list of 5 business ideas",
    "Explain the theory of relativity in simple terms",
    "Write a poem about basketball"
]

def process_prompt(prompt: str) -> str:
    response = client.chat.completions.create(
        model="gpt-4",
        messages=[{"role": "user", "content": prompt}],
        max_tokens=150,
        temperature=0.7
    )
    return response.choices[0].message.content

for p in prompts:
    print(process_prompt(p))

History of AI Technology

Artificial intelligence has progressed through multiple layers. Understanding these foundations helps you appreciate modern models:
  • Machine Learning
  • Natural Language Processing
  • Deep Learning
  • Artificial Neural Networks
The image is a diagram titled "Artificial Intelligence" that categorizes AI into four areas: Machine Learning, Natural Language Processing, Deep Learning, and Artificial Neural Networks, each with an icon.
We’ll explore key innovations like transformers, large language models, bias mitigation strategies, reinforcement learning, and the ethical frameworks guiding their use.

​
Text Generation Capabilities

OpenAI’s APIs empower you to generate, analyze, and transform natural language:
  • Prompt engineering best practices
  • Conversational agents with chat completions
  • Sentiment analysis pipelines
  • Custom OpenAI Assistants
  • Text-to-speech and speech-to-text endpoints
See the API reference for full details on parameters and response structures.

​
Core OpenAI Features

Beyond simple completions, OpenAI offers advanced tooling to structure and scale your workflows:
  • Function calling for predictable JSON outputs
  • Embeddings to implement semantic search
  • Batch processing for high-throughput scenarios
  • Advanced usage patterns like fine-tuning and orchestration

​
Vision Capabilities

OpenAI’s vision suite allows you to generate and interpret images:
  • Create images with DALL·E
  • Bridge vision and language with CLIP
  • Build OCR, classification, and synthetic media applications
  • Address ethical considerations for generative content
Below is an example of generating a custom image: 
from openai import OpenAI

client = OpenAI(OPENAI_API_KEY)

response = client.images.generate(
    model="dall-e-3",
    prompt="Brad Pitt at a golf course.",
    size="1792x1024",
    quality="standard",
    n=1
)

image_url = response.data[0].url
print(image_url)
Be mindful of usage quotas and rate limits when using high-capacity models like DALL·E-3.
