Since its release in March, OpenAI's GPT-4 model has garnered significant attention. It is primarily due to its vastly increased parameter count compared to its predecessor, GPT-3. As a result of these enhancements, GPT-4 has demonstrated an improved ability in understanding natural language and generating continuation words.

What's more, many are unaware that they can access this heightened performance and capacity of GPT-4 completely free of charge. This article provides an overview of GPT-4, its benefits and how to get free access to GPT-4.


  • GPT-4 is a language model with billions of parameters developed by OpenAI.
  • The GPT-4 is excellent at understanding natural language, reading user inputs, and generating associated outputs.
  • ZenoChat is an AI chatbot developed by TextCortex and powered by many models including GPT-4.
  • With ZenoChat you can use GPT-4 for free and enjoy  all the benefits of the GPT-4 system.

What is GPT-4?

GPT-4 (Generative Pre-trained Transformer 4), OpenAI's latest language model, has set a new benchmark for natural language processing. With over 100 trillion parameters, it is far more powerful than its predecessor GPT-3 which only had 175 million. This advanced model is capable of generating text outputs based on user inputs and promises to revolutionize the field of NLP. GPT-4 is a state-of-the-art advancement in natural language processing.

Overview of GPT-4?

When we take an overview of GPT-4, it is possible to say that it does everything that GPT-3 can do with higher quality and consistency. If you use GPT-4 to compose a blog post, the end product will be of high quality in terms of grammar, spelling, and language.

Indeed, one of the most impressive capabilities of GPT-4 is its ability to process and analyse visual inputs. By leveraging a range of parameters and AI models, GPT-4 can effectively interpret a given visual input and perform a variety of tasks accordingly. For example, GPT-4 can take an image of paper with an arithmetic problem written on it as input and solve the problem according to your command.

What are Capabilities of GPT-4?

GPT-4 (Generative Pre-trained Transformer 4) is better at understanding syntax and grammar structures than GPT-3 and GPT-3.5. It has been trained in programming languages, in addition to natural languages. Therefore, GPT-4 can do advanced coding in any programming language. If you are getting an error in your code and want to identify the source of the error, you can ask GPT-4.

One of the most impressive features of GPT-4 is its ability to generate lengthy outputs of up to 25,000 words. This capability can be particularly useful for those who need to write long-form texts or wish to check the spelling and grammar of entire book chapters.

GPT-4 vs GPT-3

There are major differences between GPT-4 and GPT-3. The most important of these differences is that GPT-4 can analyse complex inputs better, thus generating high-quality and consistent outputs. For example, if you use a chatbot powered by GPT-4 (i.e., ZenoChat by TextCortex), you will get accurate answers to your questions. Since GPT-3 is trained with internet data until June 2021, it fails to produce correct outputs about current topics.

Did you know that GPT-4 has at least 500 times more parameters than GPT-3? This means that GPT-4 has a better understanding of the inputs and can generate more consistent outputs. To put things into perspective, GPT-3 has 175 million parameters, while GPT-4 has around 100 trillion parameters. This huge difference clearly illustrates the performance disparity between the two GPT models.

Advantages of GPT-4

GPT-4, the latest and most advanced model of the GPT-n series, comes with several advantages as it has more data and parameters. It can generate more accurate, creative, and reliable outputs than its predecessors. These advantages make it a suitable AI for various purposes.

Improved Language Understanding

GPT-4 was developed using natural language processing, deep learning, and machine learning technologies. It has been trained with a vast amount of internet data, thus learning the sentence and spelling structure of various sentences, paragraphs, books, and internet texts. As a result of all this training, GPT-4 has improved language understanding in 26 languages.

OpenAI has used the MMLU (Multi-task Language Understanding) test, which consists of 14,000 multiple-choice problems covering 57 topics in 26 different languages, to test the language skills of GPT-4. In these tests, GPT-4 outperformed major language models in 24 languages.

More Parameters 

Language models like GPT-4 rely on parameters to read sentences and determine the most appropriate words to use. Unlike humans, these models prioritize choosing words with the highest probability of completing sentences, rather than truly comprehending the meaning behind them. In other words, AI chatbots can’t understand the full context or intended meaning, yet.

With a greater number of parameters, language models can more accurately calculate the odds of selecting the best continuation word. With around 100 billion parameters, GPT-4 currently boasts the highest number of parameters of any language model, making it one of the most accurate and powerful models available.

Reliable Outputs

GPT-4 generates the best output to the user's input using various parameters and datasets. The fact that GPT-4 has billions of parameters allows it to produce reliable output. Additionally, GPT-4 has a much larger amount of data than its predecessors.
