🚀 GPT Fusion

The Python toolkit that makes AI integration effortless

GPT Fusion is a comprehensive Python library designed to streamline AI-assisted application development. It ships a real LLM client for OpenAI-compatible chat completions (OpenAI, Groq, a local Ollama server, anything speaking the same API), plus the text processing, web scraping, and interactive demo tooling it's had all along.

🎯 Why Choose GPT Fusion?

• 🤖 Real LLM Client: OpenAI-compatible chat completions, works with OpenAI, Groq, local Ollama, or anything else on that API shape
• ⚡ Zero Setup Friction: Install and start coding in seconds
• 🛡️ Production Ready: Built-in security, performance optimizations, and error handling
• 🔌 Modular Design: Use only what you need with optional dependencies
• 📚 Rich Examples: Complete demo projects including Unity 3D games and auth systems
• 🧪 Battle Tested: 80+ tests with 89%+ coverage and CI/CD pipeline

🚀 Quick Start

📦 Installation

Quick Install:

pip install gpt-fusion

Full Installation (all features):

pip install "gpt-fusion[all]"

Python Version Support:

• ✅ Python 3.10+
• ✅ Python 3.11 (Recommended)
• ✅ Python 3.12

⚡ Quick Start Example

import gpt_fusion

# 🔤 Smart text processing
text = "The quick brown fox jumps over the lazy dog"
print(f"Words: {gpt_fusion.word_count(text)}")
print(f"Reversed: {gpt_fusion.reverse_words(text)}")
print(f"Is palindrome: {gpt_fusion.is_palindrome('racecar')}")

# 📊 Powerful data analysis
data = gpt_fusion.load_numbers_from_csv('data/sales.csv')
print(f"Average: {gpt_fusion.average_from_csv('data/sales.csv', use_streaming=True)}")

# 🌐 Easy web scraping (with built-in security)
headlines = gpt_fusion.scrape("https://news.ycombinator.com", "a.storylink")
print(f"Found {len(headlines)} headlines")

# 🚀 Generate complete projects in seconds
gpt_fusion.create_csv_app('my-analytics-dashboard')
gpt_fusion.create_tailwind_ui('my-modern-webapp')

Output:

Words: 9
Reversed: dog lazy the over jumps fox brown quick The
Is palindrome: True
Average: 1247.83
Found 30 headlines
✅ Created my-analytics-dashboard/ with FastAPI backend
✅ Created my-modern-webapp/ with Tailwind CSS

🤖 LLM Integration

pip install "gpt-fusion[llm]"
export OPENAI_API_KEY=sk-...

from gpt_fusion import ask, LLMClient

# One-liner for a single question
reply = ask("Explain recursion in one sentence.")

# Or reuse a client across a multi-turn conversation
client = LLMClient(model="gpt-4o-mini")
reply = client.chat([
    {"role": "system", "content": "Answer in a single sentence."},
    {"role": "user", "content": "What's a closure?"},
])
client.close()

Points base_url anywhere that speaks the OpenAI chat completions API without changing your code. Verified working against Groq's free tier:

client = LLMClient(
    base_url="https://api.groq.com/openai/v1",
    model="llama-3.1-8b-instant",
    api_key=os.environ["GROQ_API_KEY"],
)

The same pattern works for a local Ollama server (base_url="http://localhost:11434/v1") or any other OpenAI-compatible endpoint.

🎛️ Optional Feature Sets

✨ Features

🤖 LLM Client

Chat completions for OpenAI-compatible APIs - real requests, real error handling, no vendor lock-in.

# Install: pip install "gpt-fusion[llm]"
from gpt_fusion import ask, LLMClient

ask("Summarize the plot of Hamlet in two sentences.")

client = LLMClient()  # reads OPENAI_API_KEY from the environment
client.chat("Hello!", temperature=0.2)

Raises ConfigurationError if no API key is available, and APIError if the request fails or the response comes back in an unexpected shape - both importable from gpt_fusion.

🐍 Python Utilities

Core text processing, math helpers, and CSV analysis tools.

import gpt_fusion

# Text processing
gpt_fusion.word_count("Hello world")  # 2
gpt_fusion.reverse_words("Hello world")  # "world Hello"
gpt_fusion.is_palindrome("racecar")  # True

# Math & CSV
gpt_fusion.average_from_csv("data.csv")
gpt_fusion.median_from_csv("data.csv")

🌐 Web Scraping

Simple web scraping utilities with BeautifulSoup integration.

# Install: pip install "gpt-fusion[web]"
import gpt_fusion

html = gpt_fusion.scrape("https://example.com")

pyenv install 3.11.0
pyenv local 3.11.0
pip install gpt-fusion

❌ Import errors with optional dependencies

# Install specific feature sets
pip install "gpt-fusion[web]"  # for scraping
pip install "gpt-fusion[backend]"  # for FastAPI

❌ CSV files not loading

# Ensure CSV has 'value' column header
import gpt_fusion
data = gpt_fusion.load_numbers_from_csv('data.csv', use_streaming=True)
