What Is GPT-4? Key Facts and Features [August 2023]

What Is GPT-4?

GPT-4 is a powerful large language model (LLM) from OpenAI that can help with a range of tasks, from writing emails to generating code.

GPT-4 is a major advance on previous generative AI models from OpenAI, particularly in how it handles complex and nuanced prompts. More than earlier generative AI models, GPT-4 can adapt to specific tones, emotions, and genres. It can also generate code, process images, and interpret 26 languages.

While GPT-4 appears to be more accurate than its predecessors, it still invents facts—or hallucinates—and should not be used without fact-checking, particularly for tasks where accuracy is important.

GPT-4 Release Date

GPT-4 was released by OpenAI on March 14, 2023, to ChatGPT Plus subscribers and Bing search engine users. API access was also offered via a waitlist.

In May 2023, OpenAI released its mobile app for ChatGPT Plus subscribers.

What Are the New Features in GPT-4?

GPT-4 is a significant advance on GPT-3 and GPT-3.5. But how exactly is it better than these earlier models?

GPT-4 Is Multimodal

Unlike earlier models, GPT-4 has the ability to interpret images. This means you can use it to generate text from visual prompts like photographs and diagrams.

This capability is only available using the API. It’s not currently available for ChatGPT Plus subscribers using OpenAI’s apps.

Some common use cases for GPT-4’s multimodal feature include:

• Writing captions: Upload your social media image and ask GPT-4 to write a caption...
