What is GPT-4? The Ongoing Evolution of ChatGPT

Last Updated March 27, 2023


What is GPT-4 and what separates it from ChatGPT?

Hot on the heels of the release of ChatGPT comes GPT-4, OpenAI’s most advanced system, producing safer and more useful responses.

OpenAI says “GPT-4 can solve difficult problems with greater accuracy, thanks to its broader general knowledge and problem-solving abilities.”

Let’s take a quick look at what sets GPT-4 apart from ChatGPT, and the implications of this latest development.

What’s new with GPT-4?

As a refresher, ChatGPT generates human-like responses to a wide range of inputs by using natural language processing algorithms.

You can ask the AI to write essays, poems, or scripts, and even translate or summarize text. It can also even answer questions on a wide variety of topics or solve coding problems.

ChatGPT’s distinguishing feature, though, is an ability to remember previous queries so you can ask follow-up questions in a conversational way.

According to OpenAI, GPT-4 surpasses ChatGPT in its advanced reasoning capabilities.

GPT-4 can accept images as inputs and generate captions, classifications, and analyses.

It’s also capable of handling over 25,000 words of text, allowing for use cases like long form content creation, extended conversations, and document search and analysis.

Additionally, GPT-4 is more creative and collaborative than ever before. It can generate, edit, and iterate with users on creative and technical writing tasks, such as composing songs, writing screenplays, or learning a user’s writing style.

Here’s an example from OpenAI:


Explain the plot of Cinderella in a sentence where each word has to begin with the next letter in the alphabet from A to Z, without repeating any letters.


A beautiful Cinderella, dwelling eagerly, finally gains happiness; inspiring jealous kin, love magically nurtures opulent prince; quietly rescues, slipper triumphs, uniting very wondrously, xenial youth zealously.

Finally, OpenAI says GPT-4 is significantly safer to use than the previous iteration. It can reportedly produce 40% more factual responses in OpenAI’s own internal testing, while also being 82% less likely to “respond to requests for disallowed content.”

Limitations of GPT4

According to GeekWire, GPT-4 has some easily identifiable issues similar to its predecessors:

  • GPT-4 is limited by an extensive set of human-crafted “guardrails” that seek to prevent it from being offensive or off the wall.
  • It doesn’t update its knowledge in real time.
  • Its command of languages other than English is limited.
  • GPT-4 doesn’t analyze audio or video.
  • It still makes arithmetic errors that a calculator would avoid.

Most troublingly, GPT-4 still isn’t all that trustworthy. Like ChatGPT, it “hallucinates,” making up facts and even backing those facts up with made-up sources. Worse, it does so with the carefree confidence of a compulsive liar.

It’s something OpenAI is, well, open about.

“Great care should be taken when using language model outputs, particularly in high-stakes contexts, with the exact protocol (such as human review, grounding with additional context, or avoiding high-stakes uses altogether) matching the needs of a specific use-case.”

While still a real issue, GPT-4 significantly reduces hallucinations relative to previous models, they say.

The goal with any AI advancement should be to reduce bias and increase inclusivity. And you achieve that through comprehensive and properly annotated multilingual data.

Trained annotators sift through the text and label according to your needs – it’s as simple as that, but balancing cost and speed can be an issue.

How to Use GPT-4

The kicker here is that GPT-4 is only available in the ChatGPT Plus paid subscription that’ll cost you $20 a month.

The current free version of ChatGPT will still be based on GPT-3.5, which is less accurate capable by comparison.

You can, however, try it out as part of Bing Chat via Microsoft, which is free to use. Some GPT-4 features are missing from Bing Chat, though, such as visual input.

But you can still access that expanded LLM (large language model) and the advanced intelligence that comes with it.

Note: while Bing Chat is free, it is limited to 15 chats per session and 150 sessions per day.
