A Complete Guide to GPT-3.5, GPT-4, GPT-4 Turbo, and GPT-4o

The world is introduced another AI creation of OpenAI with its new model, GPT-4o. Currently, there are four different versions of ChatGPT and, therefore, it is possible to discuss significant distinctions between them. Below is a detailed information of GPT-3. 5, GPT-4, GPT-4-Turbo, and the latest addition which is GPT-4o.

What is ChatGPT?

OpenAI released ChatGPT in order to advance artificial intelligence for ordinary people. So, chat GPT can be regarded as something like a user-friendly interface as Windows for computers but for disparate AI models.

GPT-3. 5

Launch Date: March 2022

GPT-3. Supercedes GPT-3 with enhanced training with bigger data sets towards model 5. Nevertheless, this model can be used for improving methods for understanding and generation of natural language for wider ranges of texts as well as providing better consistency, relevance, and even context-sensitive understanding of the information under analysis.

Primary Use: Version that is free of charge of ChatGPT

Capabilities: We can improve the predefined messages used for hint and with the given scenarios we might enhance content creation.

Limitations: No internet access; mainly for text-related activities

Notable Variant: GPT-3. 5 Turbo

A lesser-known variant, GPT-3. 5 Turbo was a small upgrade and was mainly designed as a testing ground for GPT-4 then mainly intended for developers.


Launch Date: March 2023

GPT-4 expanded on the options of handling text and images improving overall context awareness and content generation. It supports complex reasoning as well as produces a better text that can be compared to human writing.

Primary Use: The paid versions of this software is called ChatGPT and Microsoft Copilot

Capabilities: Text and image processing, logical thinking

Limitations: higher costs of infrastructure owing to the greater amount of computing power needed

GPT-4 Turbo

Launch Date: November 2023

GPT-4 Turbo differs from GPT-4 as it has some of those computationally intensive capabilities omitted in order to save on computing requirements and expenses while not much is lost in terms of efficiency.

Primary Use: It mostly discusses the paid version of ChatGPT.

Capabilities: Real-time response- According to the interaction applications, it is effective in providing quick solutions.

Limitations: The effect on specific tasks is a slight reduction of precision.


Launch Date: May 2024

While GPT-3 has excited nerds, GPT-4o, with “o” for “omni” is the latest version, produces imprints that feel very much like actual human interlocutors. It can handle texts, images, audios, and videos; or in other words, it has the capability to memorize objects and events.

Primary Use: Before you had the [API]❓A default that you can ask all the time is ChatGPT

Capabilities: Text, image, audio, and video processing; speed of the real conversation.

Performance: Which is similar to GPT-4 Turbo for text and code reasoning, but is faster and cheaper

Unique Features: Bing with no paid searches; daily chat with characters up to ten and fallback to GPT-3. 5 for free or for relevant paid options

Privacy and Security Considerations

For each model, OpenAI provides continually sound measures for ensuring users’ privacy. For example, Recall feature on Surface devices released by Microsoft to recover deleted work is local and no images or data are transmitted over the Internet, despite this, people worry about unauthorized access.


It should be noted that OpenAI’s ChatGPT has multiple versions each of which is optimized for specific tasks. From the easily availed GPT-3. 5 to the highly advanced GPT-4o, OpenAI is not relenting in her effort to take AI capabilities to the next level, this is because there is always a model to fit every demand. Whether you endeavor on complex text analysis, image or video analysis, or perhaps want real time conversational capacities, the understanding of these models shall help in selecting for the most appropriate tool.

Read the identified trends and discover how GPT-4o is ready to step up and enhance the consumption of AI, enabling a seemingly real experience.
