"having FOMO" due to daily release to new AI models

follow along and get through your first LLM call

Step 1: Install Python 3.11

Python is the programming language we'll use to talk to the AI.

-> Go to: link

-> Scroll to the bottom of the page

-> Click "Windows installer (64-bit)"

-> Run the installer and click "Install" (make sure to check "Add Python to -PATH" if asked)

-> Verify installation: Open Command Prompt and type:

python --version

Step 2:Install VS code(it is a code editor)

-> if you don't have vs code installed , download it from link

-> Watch a quick youtube tutorial if you are new to it.

Step 3:Create GITHUB account

-> Go to link

-> Sign up with your email

-> Choose a username and password

step 4:INSTALL GIT

-> Go to: link

-> The download should start automatically

-> Run the installer and click "Next" through all the default options

-> Verify installation: Open Command Prompt and type: git --version

-> Set your identity , open git and type:

git config --global user.name "YOUR_NAME"

git config --global user.email "your@email.com"

step 5:Install uv(lightning fast python package manager)

-> Open PowerShell, run:

powershell -ExecutionPolicy ByPass -c "irm https://astral.sh/uv/install.ps1 | iex"

-> If blocked, first run: Set-ExecutionPolicy RemoteSigned -Scope CurrentUser

-> Close PowerShell, open new PowerShell window

-> Verify by this command : uv --version

step 6:YOUR FREE GROQ API

-> Go to link

-> Sign up with your google account

-> Click "API Keys" in sidebar

-> Click "Create API Key", name it "your_name"

-> IMP::COPY THE KEY (starts with gsk_...) - you cannot see it again

Step 7: Create Your Project Folder & Store API Key

-> Create a new folder on your desktop named "AI"

-> Inside your AI folder , create a new file names .env

-> open .env in notepad and paste this:

GROQ_API_KEY="gsk_your_actual_api_key"

-> save it.

VERIFY ABOVE STEPS

-> open Command Prompt and run these commands one by one, if any of these give any error go through the installation again

Step 8: Set Up Your Project in VS Code

-> open VS code

-> Press Ctrl + K then Ctrl + O (that's Ctrl+K followed by Ctrl+O)

-> Select the "AI" folder you created

-> Press Ctrl + Shift + ` (backtick) to open a terminal inside VS Code

-> In the terminal, run these commands one by one:

uv init day1

cd day1

uv venv --python 3.11

.venv\Scripts\activate.ps1

-> You'll see (day1) appear in brackets before your terminal path

Step 9:Write this command to open code llm_Call.py

-> In the VS Code terminal , create a new file:

code llm_call.py

-> This opens a new file.Copy and paste this exact code:

import os
from pathlib import Path
from dotenv import load_dotenv
from groq import Groq

load_dotenv()
my_api_key = os.getenv("GROQ_API_KEY")

if not my_api_key:
    raise ValueError("GROQ_API_KEY environment variable is not set.")

client = Groq(api_key=my_api_key)

model = "openai/gpt-oss-120b"
role = "user"
content = "Do you know VIRAT KOHLI | RONALDO?"

message = {
    "role": role,
    "content": content
}

messages = [message]

response = client.chat.completions.create(
    model=model,
    messages=messages
)

print(response)
print("################################################")

answer = response.choices[0].message.content
print(answer)

-> Save the file

Step 10:Install Dependencies and run your code

-> In the VS Code terminal, install the required packages:

uv add groq python-dotenv

-> Aha,run your first LLM call

python llm_call.py
