Quick Start Guide

Step 1: Choose Provider

export API_KEY="your-groq-api-key"
export BASE_URL="https://api.groq.com/openai/v1"
export MODEL="llama-3.1-8b-instant"

Step 2: Test Connection

curl -s "$BASE_URL/chat/completions" \
  -H "Authorization: Bearer $API_KEY" \
  -H "Content-Type: application/json" \
  -d "{\"model\":\"$MODEL\",\"messages\":[{\"role\":\"user\",\"content\":\"Hello\"}],\"max_tokens\":50}"

Step 3: Python Code

import os
from openai import OpenAI

client = OpenAI(
    api_key=os.environ["API_KEY"],
    base_url=os.environ.get("BASE_URL", "https://api.groq.com/openai/v1")
)

response = client.chat.completions.create(
    model=os.environ.get("MODEL", "llama-3.1-8b-instant"),
    messages=[{"role": "user", "content": "Hello"}],
    max_tokens=100
)
print(response.choices[0].message.content)

Step 4: Node.js Code

import OpenAI from "openai";

const client = new OpenAI({
  apiKey: process.env.API_KEY,
  baseURL: process.env.BASE_URL || "https://api.groq.com/openai/v1"
});

const response = await client.chat.completions.create({
  model: process.env.MODEL || "llama-3.1-8b-instant",
  messages: [{ role: "user", content: "Hello" }],
  max_tokens: 100
});
console.log(response.choices[0].message.content);

Tips for Student Projects

1. Use free tier - Never choose a provider without free tier
2. Portable architecture - Use OpenAI-compatible format
3. Document choices - Record provider, quota, and setup steps
4. Security - Never put API keys in GitHub

Summary

For student projects, Groq is the simplest and fastest option. For complete privacy, choose Ollama. Always design for portability to other providers.

Quick Provider Selection Script

import os

# Simple provider selector based on requirements
providers = {
    "groq": {
        "free": True,
        "credit_card": False,
        "speed": "fast",
        "models": ["llama-3.1-8b", "mixtral-8x7b"]
    },
    "together": {
        "free": True,
        "credit_card": True,
        "speed": "medium",
        "models": ["llama-3.1-8b", "mistral-7b", "many more"]
    },
    "ollama": {
        "free": True,
        "credit_card": False,
        "speed": "local",
        "models": ["any open source model"]
    }
}

needs_no_card = True  # Set based on your requirements
for name, info in providers.items():
    if needs_no_card and info["credit_card"]:
        continue
    print(f"{name}: {info['speed']} speed, models={info['models']}")

Student Project Tips

• Start free: Use Groq or Ollama for zero-cost development
• Keep it portable: Use OpenAI SDK format so you can switch providers later
• Document everything: Record which provider, model, and quota you used
• Security first: Never commit API keys to Git; use environment variables
• Build incrementally: Start with the simplest possible API call, then add features
