5 ways GPT-4 is better than older versions of OpenAI's ChatGPT

• OpenAI has announced its much-anticipated GPT-4, available to ChatGPT Plus subscribers.

• Its viral chatbot, ChatGPT, was previously powered by GPT-3.5.

• Here are five ways the update differs from GPT-3.5.

OpenAI launched GPT-4 on March 14 and says the updated version is more reliable and creative than its predecessor.

CEO Sam Altman said the tech was capable of passing the bar exam and "could score a 5 on several AP exams."

ChatGPT was previously powered by GPT-3.5. The update is available to users who pay for ChatGPT Plus and access to the API will be granted to a limited number of developers on OpenAI's waitlist.

But those who have tried Microsoft's artificial-intelligence-powered Bing have already experienced some of the new tech. On Tuesday, Microsoft said its AI-boosted Bing had been powered by a version of GPT-4 that was "customized for search."

Here are five key ways the update differs from GPT-3.5.

1. GPT-4 can understand images

GPT-4 is "multimodal," meaning it can see and process image prompts as well as text.

Users can ask the chatbot to describe images, but it can also contextualize and understand them. In one example given by OpenAI, the chatbot is shown describing what's funny about a group of images.

The chatbot is still limited to text responses and cannot produce images itself.

2. The bot is said to be more accurate

According to OpenAI, the update will give more-accurate responses to users' queries.
