OpenAI releases major GPT-4o update: what has changed

OpenAI has released a significant update to its flagship GPT-4o model, substantially expanding its capabilities in image analysis, scientific data processing, and understanding of current context.

A key improvement was the extension of training data temporal coverage from November 2023 to June 2024. This enabled the model to provide more relevant and accurate responses, especially in matters relating to cultural and social trends, as well as recent scientific research. The updated knowledge base has also improved the model’s search query efficiency.

Substantial progress has been achieved in visual information analysis. GPT-4o demonstrates improved performance in MMMU and MathVista tests, reflecting the model’s increased ability to interpret spatial relationships, analyze complex diagrams, understand graphs, and connect visual content with textual descriptions.

Developers paid special attention to enhancing the model’s capabilities in STEM (Science, Technology, Engineering, and Mathematics). GPT-4o shows improved results in solving mathematical, scientific, and programming tasks, confirmed by increased scores in GPQA and MATH academic tests. The model also demonstrated performance growth in the comprehensive MMLU test, which evaluates language understanding, knowledge breadth, and reasoning ability.

An unexpected addition was the increased use of emoji in system responses. The model now more readily applies emotional symbols, especially if users themselves use them in conversation. This innovation aims to create more natural and emotionally rich communication with artificial intelligence.
