GPT-4 is a language model created by OpenAI that belongs to the transformer class. It is the fourth model in its GPT series and was made publicly available on March 14, 2023. However, its commercial API is available only via a waitlist. The model has been trained on public as well as third-party data, using pre-training processes to predict the next token. GPT-4 has been further fine-tuned with reinforcement learning from feedback generated by humans and AI, for better alignment with human standards and policy compliance.

Microsoft has revealed that Bing has been using GPT-4 before its official release. OpenAI claims that GPT-4 is more reliable, creative and can handle much more nuanced instructions as compared to its predecessor GPT-3.5. The organization has produced two versions of GPT-4 with context windows of 8192 and 32768 tokens respectively. GPT-4 has the unique ability to process images and text as input, making it capable of describing humor in images, summarizing screen-shotted text and answering exam questions that have diagrams. Despite these advancements, GPT-4, like its predecessors, still shows tendencies to provide answers that are not entirely accurate.


    Visual Model: Most anticipated aspect of multimodal gpt-4 is the ability to process visual input, in other word images and videos.
    ChatGPT Plus: GPT-4 can be accessed by ChatGPT Plus users.
    PlaygroundAI: Playground can be used to fine tune gpt-4 and play with its parameters.
    GPT-4 API: Luckily OpenAI provides API endpoint access for gpt-4 which gives AI developers many opportunities to build on the model.

Fune Tuning / Tips:

  • Max tokens: Defines maximum token amount for input, now up to 32K.
  • temperature: Can be used to adjust focus of the model to more creative or more focused.
  • n: Can be used to run the model n multiple times on the same prompt.
  • stop: Can be used to make the AI model stop generating response when certain token is encountered.
  • top_p: Parameter to adjust nucleus sampling of the AI model.

GPT-4 Pros:

  • Unseen accuracy of responses
  • Improved AI responsibility for disallowed and insensitive prompts
  • Higher maximum prompt size, default 8K tokens up to 32K
  • Multimodal Large Language Model
  • Capability of processing visual input
  • GPT-4 is more advanced in creativity, allowing it to generate more imaginative and innovative responses
  • It can analyze more complex and nuanced language

GPT-4 Cons:

  • Trained with 2021 data similar to ChatGPT with gpt-3.5-turbo
  • More expensive than gpt-3.5-turbo
  • GPT4 is slower than GPT-3.5-turbo, which can hinder certain use cases
  • The model can be prone to hallucinations, Generating factually incorrect or nonsensical outputs
  • No references to support its claims
  • Still not very good at reasoning

GPT-4 Price:

App pricing information for GPT-4 is as below:

Price: $20 through ChatGPT Plus, API Prices are as following.
8K model: $0.03/1k prompt tokens, $0.06/1k sampled tokens.
32K model: $0.06/1k prompt tokens, $0.12/1k sampled tokens

Q: What is OpenAI?
A: OpenAI is an AI research laboratory consisting of the for-profit OpenAI LP and the non-profit OpenAI Inc. It was co-founded by Elon Musk and other prominent entrepreneurs with the goal of advancing and promoting friendly AI for the benefit of humanity.
Q: What is a Multimodal AI Model?
A: A multimodal AI model is a machine learning model that can process and analyze data from multiple modalities, such as text, images, videos, and audio. GPT-4 is touted to be a large multimodal AI model which can handle much more nuanced instructions than GPT-3.5.
Q: How does GPT-4 differ from GPT-3.5?
A: The main distinction between GPT-3.5 and GPT-4 is that the latter is expected to be a much larger model capable of handling more complex tasks, including multimodal input.
Q: How can GPT-4 be used?
A: GPT-4 can be used for various professional and academic applications such as natural language processing, chatbots, AI systems, and many others. It is expected to outperform GPT-3 in terms of its capabilities and customization.
Q: What are the capabilities of GPT-4?
A: GPT-4 is expected to be a large multimodal AI model that can handle much more nuanced instructions than GPT-3.5 version. It will feature improved reasoning abilities and better detection of reasoning errors. Also, it will be able to respond even to requests that are not supported in the previous models.
Q: When will GPT-4 be released?
A: OpenAI has not yet announced a specific release date for GPT-4, but the model is under development already.
Q: How can I get access to GPT-4?
A: GPT-4 is not yet available to the general public, but some researchers and organizations can apply for access to the model through OpenAI’s waitlist.
Q: What is Bing Chat?
A: Bing Chat is an AI-powered chatbot API developed by Microsoft that is built on the GPT-3 language model. It is being used to create virtual assistants which are capable of responding to requests for disallowed content.
Q: Can GPT-4 handle image input?
A: Yes, GPT-4 is expected to be a large multimodal AI model, which means it will be capable of handling data from multiple modalities including text, images, videos, and audio.
Q: What is the Bar Exam for AI Language Models?
A: The Bar Exam for AI Language Models is a test created by OpenAI, to evaluate the performance of large language models in various tasks, such as answering questions, writing essays, and more. While GPT-3 scored well on this test, GPT-4 is expected to perform even better.
Q: Is gpt 4 open source?
A: No, GPT-4 is a closed-source AI model developed by OpenAI.
Q: What’s the difference between gpt-4 and gpt-3.5-turbo?
A: According to OpenAI, GPT-4 performs better than ChatGPT — which is based on GPT-3.5—because it is more sophisticated and offers advanced features.
Q: Is gpt-4 free?
A: GPT-4 can be accessed by ChatGPT Plus users. Additionally, Quore Poe offers a limited free access to GPT-4. Overall, you can try GPT-4 for free but as an advanced AI model it's a bit costly and you would need to purchase ChatGPT Plus or other premium subscriptions that offer GPT-4.
Q: Does gpt-4 have an API?
A: Yes. GPT-4 can be accessed via OpenAI's API platform by AI developers just like other OpenAI AI models.
