# OpenAI's GPT Engines Overview

At **FormWise**, we always integrate the **latest OpenAI GPT models**, ensuring you have access to **the most powerful AI engines** without any manual updates on your end.

If you're not sure which model to use, **we recommend GPT-4o or higher** for the best performance. It’s **smarter, faster, and more cost-effective** than previous versions.

### What Are GPT Engines?

GPT engines are **AI-powered text generators** that help create human-like responses. They’re trained on vast amounts of data and can assist with:

✅ Writing product descriptions, emails, and content\
✅ Answering customer questions via chatbots\
✅ Summarizing and analyzing information\
✅ Generating creative and marketing ideas

Each **newer version** of GPT improves in **speed, accuracy, and cost efficiency**.

### **Which GPT Model Should You Use?**

#### **🚀 GPT-4o (Recommended)**

💡 **Fastest, most advanced, and most affordable GPT model**

✅ Best for **all use cases** (content generation, chatbots, automation)\
✅ **More accurate** than older models\
✅ **Faster and cheaper** than GPT-4

💡 **Use GPT-4o for:**

* **AI chatbots** that need fast, smart replies
* **Writing high-quality product descriptions & sales copy**
* **AI-powered customer support**

***

#### **🚀 GPT-4o Turbo**

💡 **An optimized version of GPT-4o with even more efficiency**

✅ **For large-scale applications** needing super-fast AI processing

***

#### **⚡ Older Models (Only Use If Needed)**

* **GPT-3.5 Turbo / GPT-3.5 Turbo 16k** – Slower and less accurate, but still useful for budget-conscious tasks.
* **GPT-3.5 Instruct** – Designed to follow instructions but is outdated compared to GPT-4o.
* **GPT-4.5 Research Preview** – Early-stage experimental model with potential improvements.

💡 **We strongly recommend switching to GPT-4o instead of using older models.**
