GPT-4 Turbo: An Advanced Version of GPT-4 Announced at OpenAI's DevDay

Meet GPT-4 Turbo, OpenAI's cutting-edge language model, poised to redefine AI capabilities with unprecedented speed, precision, and intelligence. The future of natural language processing has arrived.

In a groundbreaking revelation, OpenAI introduces GPT-4 Turbo, a pinnacle in the AI field. This turbocharged marvel signifies a quantum leap in natural language processing, boasting unparalleled speed and cognitive finesse. GPT-4 Turbo transcends its predecessor, GPT-4, with a larger context window and updated knowledge cutoff.

This transformative leap underscores OpenAI's commitment to advancing the frontiers of AI, promising a future where technology augments human potential in unprecedented ways.

What is GPT-4 Turbo?

On OpenAI's first ever DevDay event, company's CEO Sam Altman announced OpenAI's most recent generation model is the GPT-4 Turbo, which is much more powerful, features a 128k context window (the equivalent of 300 pages of text in a single prompt) and has an updated knowledge cutoff date of April 2023.

In comparison to the original GPT-4 model, the model is also 2X cheaper for output tokens and 3X cheaper for input tokens. For this model, 4096 output tokens are the maximum.

This turbocharged version is engineered for superior performance, enabling many applications from intricate problem-solving to creative content generation. GPT-4 Turbo signifies a watershed moment in AI evolution, showcasing OpenAI's commitment to pushing the boundaries of what's possible in intelligent computing.

Key features of GPT-4 Turbo:

Following are some key features of GPT-4 Turbo:

  • Enhanced Context Length: GPT-4 Turbo boasts a remarkable context length of up to 128,000 tokens, a significant leap from the previous 8,000 token limit. This expanded capacity empowers users to tackle extensive documents and lengthy contexts with greater efficiency. Meaning that you can seamlessly write a prompt of 300 pages of text,
  • Improved Function Calling Capabilities: GPT-4 Turbo elevates the user experience by enhancing its ability to handle function calls effectively. Users can now invoke multiple functions simultaneously, streamlining the process and aligning more precisely with user instructions. This enhanced responsiveness fosters a more seamless and intuitive interaction with the model.
  • New Knowledge Cutoff: GPT-4 Turbo eliminates the persistent reminder that its knowledge cutoff date is restricted to September 2021. This means users can access and process information more freely without the constant reminder of a dated knowledge base as its knowledge cutoff date is updated to April 2023.
  • Enhanced Instruction Following: GPT-4 Turbo excels at adhering to user instructions, particularly in tasks that demand meticulous attention to detail. For instance, the model can now consistently generate specific formats, such as XML, demonstrating its improved ability to follow instructions and meet user requirements.
  • Affordable Pricing for Developers: OpenAI has committed to making GPT-4 Turbo accessible to a wider range of developers by offering it at a significantly reduced price compared to its predecessor, GPT-4. This reduced pricing structure lowers the barrier to entry for developers seeking to integrate the model's powerful capabilities into their applications.
  • Multiple Tools in One Chat: GPT-4 Turbo consolidates multiple tools within a single chat interface, streamlining the user experience. Users can access a variety of tools, including the Text-to-Speech API, the DALL-E 3 API, and the GPT-4 model itself, all within a unified platform. This consolidation simplifies workflow and enhances user convenience.

How to access GPT-4 Turbo?

Currently, GPT-4 is available in preview for developers only via APIs. Accessing GPT-4 Turbo involves creating an OpenAI API account and establishing an OpenAI billing account. Once these accounts are set up, developers can access GPT-4 Turbo by passing "gpt-4--1106-preview" as the model name in the OpenAI API. Additionally, GPT-4 Turbo is available through ChatGPT Plus, offering a usage cap for interactions with the model via Accessing GPT-4 Turbo is streamlined for user convenience. OpenAI offers API access, allowing developers to integrate the model into their applications effortlessly.


GPT-4 Turbo's pricing structure is designed to be simple and flexible, allowing developers to pay only for what they use. The model is priced per 1,000 tokens, where a token is roughly equivalent to a word. The current pricing for GPT-4 Turbo is as follows: Input tokens: $0.01 per 1,000 tokens. Output tokens: $0.03 per 1,000 tokens.

Key takeaways:

  • GPT-4 Turbo processes up to 128,000 tokens, equivalent to 300 book pages, enabling comprehensive analysis and understanding.
  • Provide more detailed instructions and context for refined results, enhancing the model's responsiveness.
  • Its knowledge cutoff is updated to April 2023
