07 Jun ChatGPT models explained: How to use each, according to OpenAI

Since the release of OpenAI’s ChatGPT, users around the world have embraced the tool for tasks ranging from writing assistance and data analysis to customer support and creative brainstorming. However, many users are unaware that multiple models of ChatGPT exist, each tailored for different needs and capabilities. According to OpenAI, understanding which model to use—and how to use it—can significantly improve user experience and outcomes.

Understanding the ChatGPT Models

OpenAI provides access to several ChatGPT models through its user interface and API. These models include variations trained on different data, equipped with distinct capabilities, and optimized for specific use cases.

1. GPT-3.5

This model is the default free-tier ChatGPT available to all users. It excels at basic conversation, simple coding tasks, and general knowledge queries. While powerful, GPT-3.5 may struggle with highly specific, technical, or nuanced prompts, and does not have access to real-time or recent data updates beyond its training cutoff.

2. GPT-4

Available to ChatGPT Plus subscribers, GPT-4 offers substantial improvements in reasoning, comprehension, and context retention. It performs well in multilingual communication, advanced programming, and complex writing tasks.

One of GPT-4’s key features is its ability to handle more extended prompts and generate more coherent, structured outputs over longer interactions.

3. GPT-4-turbo

OpenAI has also introduced GPT-4-turbo, a variant of GPT-4 designed to be cheaper and faster while maintaining similar performance levels. GPT-4-turbo is the version used in ChatGPT Plus as of 2024 and supports additional tools such as image interpretation, code execution, and file uploads—as part of ChatGPT’s “pro” suite of features.

How to Use Each ChatGPT Model Effectively

Users access these models through OpenAI’s ChatGPT web app or via the API. Here’s how to make the most out of each:

• GPT-3.5: Best suited for casual queries, grammar correction, summaries, and straightforward code generation. Use when you need quick, general insights without subscribing to premium tiers.
• GPT-4: Ideal for in-depth research, detailed explanatory writing, or complex coding. Its improved contextual understanding makes it the model of choice for professional and academic work.
• GPT-4-turbo: Use this version when you need advanced features like analyzing uploaded documents or generating visuals. It provides both power and flexibility, especially with longer context windows and access to ChatGPT Tools.

OpenAI’s ChatGPT Tools with GPT-4-turbo

When using GPT-4-turbo via a ChatGPT Plus account, users can access several integrated tools:

• Code Interpreter: Also known as “Advanced Data Analysis,” it can run Python code to analyze data, create charts, or process files.
• Browse with Bing: Allows ChatGPT to access and summarize real-time web content.
• DALL·E Integration: Used to generate images from text prompts and even edit them interactively.
• File Uploads: Users can upload documents for the AI to read and analyze directly.

These tools dramatically expand what GPT-4-turbo can accomplish, especially in professional and research settings.

Choosing the Right Model for Your Needs

When deciding which model to use, consider the complexity of your task, the sensitivity of your data, and whether you require real-time or multimodal features. For instance, a student writing a paper might benefit more from GPT-4, while a business user analyzing spreadsheets and images should rely on GPT-4-turbo and its additional tools.

Being strategic about model selection ensures faster response times, better-quality outputs, and more efficient use of resources.

FAQ
