The company’s text rendering technology has been upgraded to version 4 under the name GPT-4.
GPT-4, a new and improved version of ChatGPT, which provides great advances in artificial intelligence, was released in March. So what is the difference between GPT-4 and ChatGPT-3.5? Is it worth paying for? We explained what you need to know in the rest of our article.
ChatGPT, OpenAI’s Natural Language Generation (NLG) tool that automatically generates text, took the tech world by storm in late 2022 (just as Dall-E rendering AI did earlier that year). Now the company’s text rendering technology has been upgraded to version 4, under the name GPT-4. But are you using the new technology yet?
What’s new in GPT4?
OpenAI has actually been releasing GPT versions for almost five years. It first became publicly available in 2020, spurring AI announcements from other big names (including Microsoft, which eventually invested in OpenAI).
TechTarget defines parameters as “pieces of a large language model that describe its skill at a problem like text generation.” This is basically what the model learns. GPT-1 had 117 million parameters to work with, GPT-2 had 1.5 billion parameters, and GPT-3 arrived in February 2021 with 175 billion parameters. By the time ChatGPT was released to the public in November 2022, the technology had reached version 3.5. So if you are using the free version of ChatGPT, you will be using GPT-3.5 for a while.
How can I try GPT-4?
As ChatGPT quickly became popular, this caused server capacity issues. So it didn’t take long for OpenAI to offer a paid version of the technology. That didn’t slow things down much; ChatGPT (both paid and free versions) eventually attracted as much web traffic as the Bing search engine. As Cio Update did our research, we learned that there are still moments when the basic ChatGPT exceeds capacity.
The paid version is called ChatGPT Plus (or ChatGPT+). It costs $20 per month. OpenAI started piloting Plus in early February (it went global on February 10); ChatPGT+ is now the primary way for people to access basic GPT-4 technology.
First you need a free OpenAI account. Then look for the Upgrade to Plus link in the menu. You may not be able to log in if there is a capacity issue, which is one of the things ChatGPT+ is supposed to eliminate.
Is ChatGPT+ worth paying 20 dollars?
The statistics presented by OpenAI are impressive. Comparing GPT-3.5 to GPT-4, the company says GPT-4 is 82% less likely to respond to prompts when they are not technically allowed, and 60% less likely to fabricate facts, called “hallucinations” in AI terms. (Also, in tests conducted by the non-profit Alignment Research Center, GPT-4 was able to social engineer its way past a real human on TaskRabbit.)
