OpenAI's GPT-4 Turbo Comes on Stage: Here's All You Need to Know

Recently, OpenAI conducted its inaugural DevDay to unveil the new GPT-4 Turbo. What should be paid attention to and what benefits do these new features bring? Let's explore the highlights of the GPT-4 Turbo.

• Context Length with 128K

The context window has increased to 128k tokens, equivalent to about 300 pages of text. Compared to the previous GPT-4, which could only handle 8k tokens, its capacity has been increased by 16 times. This feature can not only provide more background information but also make the reply more logical and cohesive.

• JSON Mode & Function Calling

The developers are given more freedom with JSON mode and function calling. The developer can describe the functions of the application or external API to the model with function calling and let the model intelligently select the output JSON object containing the parameters to call these functions. It can call more than a function in a single conversation: you can send a single message requesting multiple operations.

• Knowledge Update

The GPT-4 turbo knowledge has been updated to April 2023 while the previous version only had knowledge prior to September 2021.

• New Modalities in API

The Assistant API was integrated DALL·E 3, GPT-4 Turbo with vision and TTS (text-to-speech). DALL·E 3 was built into a proper check function for helping the developers protect their applications from being misused. GPT-4 Turbo with vision can accept images as inputs via the API and generate captions, analysis, and reading documents with figures. TTS provides six preset voices to select and there are also versions optimized for real-time use cases, as well as for quality.

• Model Customization

This feature is major specialized for those enterprise organizations, they can take part in the OpenAI team’s research to train customized GPT-4 in special domains. The organization owns the access authority without sharing with other organizations or training other models. Also, the proprietary data provided to OpenAI for training custom models is not reused in any other context.

• Higher Rate Limits

To help users scale the app, OpenAI has doubled the token per minute limit for all paying GPT-4 customers.

• Other Features

Copyright Shield: OpenAI provides a Copyright Shield to protect users' rights and bears the liability for damage.

More Economical Price: Compared to GPT-4, its input Token is a third of the price and its output Token is half the price.

• Conclusion

OpenAI has demonstrated its deep insight and strong innovation in the field of artificial intelligence. Its technologies not only provide users with smarter, more personalized, and diversified AI services but also open up new possibilities for the development and application of artificial intelligence.
