OpenAI recently announced GPT-4 Turbo, an upgraded version of their powerful language model GPT-4. There are several key differences that make GPT-4 Turbo more advanced and worth paying attention to. Let’s take a look.

Larger context window

One major upgrade with GPT-4 Turbo is its larger context window. Context refers to the amount of text the AI can process at a time. GPT-4 Turbo can handle up to 128,000 tokens, equivalent to around 300 pages of text. This is one of the largest context windows in any large language model today. Meanwhile, GPT-4 is limited to a more humble 8,000 tokens or 24 pages.

This larger context window allows GPT-4 Turbo to deeply understand more information and make connections across broader documents. With more context, the AI can provide smarter, more nuanced responses beyond just the last few sentences it reads. The expanded knowledge leads to more coherent conversations and thoughtful analysis.

More up-to-date knowledge

Another advantage of GPT-4 Turbo is its knowledge has been updated to April 2023, whereas GPT-4 is current only through September 2021. With more recent information, GPT-4 Turbo can discuss and understand the latest events, research, and facts.

Staying up-to-date is crucial for an AI assistant. Outdated knowledge leads to incorrect or ignorant responses. GPT-4 Turbo’s knowledge refresh keeps it relevant and useful for today’s conversations.

Cheaper to run

According to OpenAI, GPT-4 Turbo also costs less for developers to use. Input is just $0.01 per 1,000 tokens, compared to $0.03 for GPT-4. Output is $0.03 per 1,000 tokens. Overall, the newer model is 3 times cheaper than previous versions.

The lower cost makes the advanced AI more accessible to developers. Companies and researchers can experiment with GPT-4 Turbo without spending as much. This wider availability will likely accelerate innovation in AI applications.

Available in preview now

Finally, GPT-4 Turbo is already accessible in preview by passing “gpt-4-1106-preview” in the API. OpenAI plans to officially launch the stable production-ready model in the coming weeks.

Meanwhile, GPT-4 was first released back in March and made generally available in July. By tapping into the preview, developers can start integrating and testing with GPT-4 Turbo today.
