Artificial intelligence research leader OpenAI has recently unveiled GPT-4, the latest iteration of their highly influential language model. This comprehensive report aims to provide an in-depth analysis of GPT-4's capabilities, potential applications, and notable improvements over previous versions. Additionally, it will explore the limitations and potential risks associated with the deployment of GPT-4.

1. GPT-4 Capabilities

GPT-4 represents a significant leap forward in language modeling, as it is a multimodal model capable of accepting image and text inputs while generating text outputs. The development process involved a 6-month iterative alignment process that benefited from OpenAI's expertise gained from the adversarial testing program and ChatGPT. As a result, GPT-4 offers enhanced reliability, creativity, and the ability to handle more nuanced instructions compared to its predecessor, GPT-3.5.

2. Training Process and Scaling

OpenAI has dedicated the past two years to rebuilding its deep learning stack and collaborating with Azure to design a supercomputer tailored to their training workload. GPT-3.5 served as a test run for GPT-4's training, allowing OpenAI to identify and address bugs while improving foundational aspects. GPT-4 became the first large-scale model where OpenAI could accurately predict training performance. This scalable training process facilitates accurate loss metric predictions and superior performance across multiple languages.

3. Language and Image Input Capabilities

GPT-4 offers text input capabilities through ChatGPT and an API. OpenAI is also actively developing image input capabilities in partnership with a collaborator. GPT-4's capabilities extend to processing various domains, including documents with text and photographs, diagrams, or screenshots. However, the image input feature is currently in the research preview stage and not publicly available.

4. Performance and Benchmarking

GPT-4 has demonstrated human-level performance on various professional and academic benchmarks. It excels in simulated exams designed for humans and outperforms existing large language models and state-of-the-art models in machine learning benchmarks, including languages other than English. Testing in 26 languages has revealed GPT-4's superiority in 24 languages, even for low-resource languages like Latvian, Welsh, and Swahili.

5. Potential Applications

OpenAI has experienced significant positive impacts across multiple functions by utilizing GPT-4 internally. These functions include support, sales, content moderation, and programming. GPT-4 has also played a crucial role in evaluating AI outputs, marking a significant milestone in OpenAI's alignment strategy. GPT-4's advanced capabilities open up possibilities for researchers, developers, and the wider community in exploring and utilizing advanced natural language processing technologies.

6. Steerability and Customization

OpenAI has made significant advancements in GPT-4's steerability, enabling users to customize AI style and tasks using system messages. This feature offers users the ability to customize GPT-4's behavior within predefined bounds. OpenAI acknowledges the need for ongoing improvements in adhering to these bounds, as customization must be done in a responsible and ethical manner.

7. Limitations and Challenges

While GPT-4 showcases enhanced capabilities, it is important to note its limitations. GPT-4 is not fully reliable and may occasionally generate hallucinations or reasoning errors. OpenAI advises caution when utilizing the model's outputs, especially in high-stakes applications. Although GPT-4 aims to reduce hallucinations and improve factuality, it may still occasionally miss subtle details.

8. Addressing Biases and Public Involvement

OpenAI actively works to address biases in GPT-4's outputs and seeks public input to define boundaries and defaults that reflect a wide range of user values. Involving the community is a crucial aspect of OpenAI's mission to create AI systems that benefit humanity. Transparency and inclusivity in decision-making processes help mitigate biases and ensure fairness in AI development.

9. Subscription Plans and API Access

GPT-4's capabilities are made accessible through the ChatGPT Plus subscription. OpenAI also plans to introduce a new subscription level in the future for higher-volume usage. Developers can sign up for OpenAI's waitlist to gradually access GPT-4's API. OpenAI's Researcher Access Program also provides subsidized access to researchers studying the societal impact of AI.

10. Evaluation and Feedback

OpenAI has developed OpenAI Evals, a framework for automated evaluation of AI model performance. This framework allows users to report shortcomings and contribute to further improvements, enabling better evaluation and refinement of models like GPT-4. User feedback is invaluable in driving continuous enhancements and ensuring the responsible deployment of AI technologies.


OpenAI's GPT-4 represents a significant advancement in language models, offering enhanced capabilities, improved reliability, and the ability to process text and image inputs. While GPT-4 has its limitations and associated risks, OpenAI actively works on refining the model, addressing biases, and ensuring better overall performance. The introduction of GPT-4 brings promising possibilities for researchers, developers, and the wider community to explore and utilize advanced natural language processing technologies effectively.
