What is GPT-4 Turbo?

Hey Xploras! So, you might have heard about GPT-4, but have you met its turbo-charged cousin, GPT-4 Turbo? Let’s dive in and explore what makes this next-generation language model a game-changer.

What is GPT-4 Turbo?

OpenAI CEO Sam Altman on Monday announced the release of GPT-4 Turbo at DevDay. The latest version of its natural language AI. GPT-4 Turbo is the next generation of OpenAI’s language model, which builds upon the previous GPT-4 version. It’s designed to be even more capable and knowledgeable about world events up to April 2023.

One of the key features that make GPT-4 Turbo stand out is its expansive context window. What’s that, you ask? Well, it’s like giving the model a much bigger playground to work with.

You see, GPT-4 Turbo has a whopping 128k context window. In simpler terms, it can handle the equivalent of more than 300 pages of text in a single prompt. This means it can provide even more context and information in its responses.

For example, if you were to ask it about the plot of a novel, it could take into account the entire book, not just a single paragraph or sentence. This helps in generating richer and more informative answers.

So, whether you’re writing an essay, getting insights for your research, or simply having a chat with GPT-4 Turbo, you can expect a deeper level of understanding and information. It’s like having an expert by your side, offering insights from a vast library of knowledge.

How Does GPT-4 Turbo Differ From GPT-4?

GPT-4 Turbo differs from GPT-4 in the following ways:

Feature GPT-4 Turbo GPT-4
Context Window 128k context window About 8,000 words
Cost-Effectiveness 3x cheaper input tokens, Higher cost for input
2x cheaper output tokens and output tokens
Knowledge of Events Up to April 2023 September 2021
Function Calling Enhanced, supports Basic function calling
multiple actions in a capabilities
single message
Instruction Following Superior performance in Standard instruction
and JSON Mode following specific following capabilities
instructions and JSON mode
Reproducible Outputs Introduces the seed Not available
parameter for consistency

These are some of the key distinctions between GPT-4 Turbo and its predecessor, GPT-4.

Is GPT-4 Turbo Free?

The short answer is no, it’s not free, but it does come with some significant cost benefits for developers.

Compared to its predecessor, GPT-4, GPT-4 Turbo offers some exciting advantages in terms of pricing. It’s like getting a more powerful engine for your car without breaking the bank.

Here’s what you need to know:

  • 3x Cheaper Input Tokens: GPT-4 Turbo comes with a 3x reduction in the price of input tokens ($0.01 per 1,000 tokens) compared to GPT-4 ($0.03 per 1,000 tokens). This is fantastic news for developers who want to interact with the model without burning a hole in their budget.
  • 2x Cheaper Output Tokens: Not only are input tokens more affordable, but output tokens are also 2x cheaper with GPT-4 Turbo ($0.03 per 1,000 tokens) compared to GPT-4 ($0.06 per 1,000 tokens). This means you can generate more responses without worrying too much about the cost.

While these prices are more cost-effective compared to its predecessor, GPT-4, it’s important to note that GPT-4 Turbo is not offered for free.

How to Access GPT-4 Turbo

Accessibility is a key factor when it comes to utilizing cutting-edge technology like GPT-4 Turbo. OpenAI has made it incredibly accessible for developers who are eager to tap into its capabilities.

Here’s what you should know:

  • API Availability: GPT-4 Turbo is available through the API. This means developers can integrate it into their applications, websites, and services seamlessly. The API is the gateway to unlocking the capabilities of GPT-4 Turbo.
  • Preview Release: As of now, there is a preview version of GPT-4 Turbo that developers can try. It’s a chance to get a taste of what this model can do and start experimenting with it.
  • Stable Production-Ready Model: OpenAI has plans to release a stable production-ready version of GPT-4 Turbo in the near future. This means that developers can confidently incorporate it into their projects for reliable and robust performance.

Function Calling Enhancements

Next, let’s explore the enhancements in function calling. You know, they say that good things come in pairs, and in the world of AI and function calling, OpenAI has certainly delivered!

Here’s what’s new in this area:

  1. Requesting Multiple Actions with a Single Message: Picture this: you’re chatting with a model, and you want it to do a bunch of things, like opening a car window and turning off the A/C. In the past, this would have required multiple back-and-forths with the model, but not anymore. With GPT-4 Turbo, you can now ask for multiple actions in a single message. It’s like giving your AI assistant a to-do list, and it understands and delivers. This not only makes interactions smoother but also more efficient.
  2. Enhanced Function Calling Accuracy: Have you ever asked a question, and the response you got didn’t quite match what you were looking for? With GPT-4 Turbo, the chances of that happening are even slimmer. This new model is impressively accurate in returning the right function parameters. It’s like having a conversation with someone who really gets what you mean, down to the details. This accuracy is a game-changer, especially when you need precise and reliable results.

Improved Instruction Following and JSON Mode

Here’s where things get really exciting, especially if you’ve ever had to work with AI models that struggled with following specific instructions:

  1. Specific Instruction Mastery: GPT-4 Turbo is like the attentive student in class who never misses a word the teacher says. When it comes to following instructions, this model excels. If you need it to generate text in a specific format, like “always respond in XML,” it will do just that. This is a massive step forward for those who rely on AI for tasks that require precise adherence to instructions.
  2. The JSON Mode Advantage: JSON is a common data format used in web development, and GPT-4 Turbo is now fluent in it. If you ask the model to respond with valid JSON, it does so seamlessly. This is a boon for developers who work with JSON, as it ensures that the responses they receive are structured and easily usable in their applications.

Reproducible Outputs

This one is for those who appreciate consistency and control in their interactions with AI. OpenAI has introduced a new feature known as the “seed parameter,” and it’s a bit of a game-changer:

  1. Reproducible Outputs: Think of the seed parameter as a way to get predictable outcomes from the model. When you set a specific seed, GPT-4 Turbo will generate outputs that are consistent with that seed most of the time. It’s like having a secret code to get the same answer whenever you want it. This feature is incredibly handy for debugging, unit testing, and any scenario where you need to ensure the model’s behavior is predictable and consistent.

These enhancements in function calling, instruction following, and reproducible outputs with GPT-4 Turbo bring a new level of reliability, accuracy, and control to AI interactions. It’s like having a super-smart and dependable assistant at your disposal, ready to tackle your tasks and deliver the results you need. These improvements open up exciting possibilities for developers and users alike, making AI more versatile and user-friendly.


In a nutshell, GPT-4 Turbo is a powerhouse of a language model, with its expanded context, cost-effectiveness, and developer-friendly features. It’s not just about understanding words; it’s about understanding your needs. Whether you’re into content creation, data analysis, or building innovative applications, this model is here to empower you.
