5 款可取代昂貴雲端 API 的本地 AI 工具

The Problem With Cloud AI

Every token costs money. Every API call adds up. And your data goes to their servers.

The Local Alternative

brew install ollama
ollama pull llama3.2
ollama serve

Now you have a GPT-4 level model running on your MacBook. Free. Private. Fast.

Real Code Example

import requests

def ask_local_ai(question):
    r = requests.post(
        "http://localhost:11434/api/generate",
        json={"model": "llama3.2", "prompt": question, "stream": False}
    )
    return r.json()["response"]

# Works immediately, no API key needed
answer = ask_local_ai("Explain Docker in one paragraph")
print(answer)
