Ai Api Usage in AI & ML
You don't need to train your own AI model to build AI-powered apps. Most developers use AI APIs — pre-built AI services exposed as web endpoints. You send text, get back AI-generated responses.
Major AI APIs: OpenAI (ChatGPT/GPT-4), Google Gemini API, Anthropic Claude API, Hugging Face Inference API, Cohere, Mistral. All work similarly: send HTTP request with your text, receive AI-generated response in JSON.
API Key: To use any AI API, you register and get an API key — a secret password that identifies your account. API calls cost money (typically per 1000 tokens). Free tiers exist for learning.
Python usage: Install the library (pip install openai), set your API key, and call the API. The response is a Python object with the AI's generated text. You can build complete AI apps in under 50 lines of Python.
Ai Api Usage — Syntax
# OpenAI Python API (conceptual — needs actual API key):
# from openai import OpenAI
# client = OpenAI(api_key="your-key")
# response = client.chat.completions.create(
# model="gpt-4o-mini",
# messages=[{"role": "user", "content": "Explain recursion"}]
# )
# print(response.choices[0].message
