  • 2-1. Definition and Core Features

  • GPT-4o, OpenAI’s new flagship multimodal model, can process and generate text, audio, image, and video in real time, enabling natural and human-like interactions across these formats. The model supports real-time reasoning and responses, enhancing communication between humans and AI. It provides faster, more accurate translations and supports over 50 languages, offering improved processing speeds for diverse applications. The core features of GPT-4o include real-time audio, vision, text processing, and enhanced translation capabilities across multiple languages.

  • 2-2. Release Announcement

  • On May 13th, OpenAI officially launched GPT-4o, introducing it as their latest multimodal model at the Google I/O conference. The 'o' in GPT-4o stands for 'omni,' highlighting its comprehensive capability to integrate various forms of input and output, including text, audio, and video. OpenAI's CTO, Mira Murati, emphasized the model's ability to deliver more natural and human-like interactions. GPT-4o responds in as little as 232 milliseconds and averages 320 milliseconds for audio replies, which is significantly faster compared to previous models. This model is also cost-effective, processing tasks at half the cost of its predecessor, GPT-4 Turbo, while offering improved language and vision processing capabilities.

3. Technical Capabilities of GPT-4o

  • GPT-4o is designed for real-time processing across multiple modalities, including text, audio, vision, and video. This capability allows GPT-4o to handle and integrate various types of input simultaneously, setting a new standard for natural human-computer interaction. GPT-4o integrates these inputs using a single neural network, which differentiates it from previous models that required multiple steps to process such inputs.

  • 3-2. Response Speed

  • GPT-4o boasts significantly improved response times, with the ability to process audio inputs in as little as 232 milliseconds, averaging around 320 milliseconds. This is a substantial enhancement from past models (e.g., GPT-3.5 with 2.8 seconds and GPT-4 with 5.4 seconds). These response speeds make interactions with GPT-4o feel almost as fast as human conversation, enhancing usability and user experience.

  • 3-3. Improved Reasoning and Comprehension

  • The model shows superior reasoning abilities, achieving an impressive score of 88.7% on 0-shot COT MMLU (general knowledge questions) and 87.2% on the traditional 5-shot no-CoT MMLU. These scores mark a significant improvement over previous models and highlight GPT-4o's capability for advanced reasoning and comprehension.

  • 3-4. Vision and Audio Understanding

  • GPT-4o exhibits advanced understanding in both vision and audio processing. It surpasses previous models on various performance benchmarks, including Whisper-v3, especially in speech recognition and translation. GPT-4o excels in visual perception tasks, as demonstrated in the M3Exam, which includes multilingual and vision evaluation through multiple-choice questions that sometimes involve visuals. The model sets new high scores on these tests, confirming its advanced multimodal understanding.

  • 3-5. Language Support and Tokenization

  • GPT-4o supports an extensive range of languages with significantly fewer tokens required for processing. For instance, GPT-4o reduces token count by up to 4.4x in languages like Gujarati and 3.5x in Telugu. This reduced tokenization improves performance and efficiency across various languages, including Korean, Japanese, Arabic, and many more. The model also ensures high-quality and rapid translations, making it highly effective for multilingual communication.

  • GPT-4o has been demonstrated as a proof of concept in customer service applications. It can handle conversations with a latency as low as 232 milliseconds, making interactions feel almost instantaneous. Unlike its predecessors, GPT-4o processes all inputs and outputs through a single neural network, allowing it to maintain context and understand tone, multiple speakers, and background noises, thus significantly enhancing customer service experiences.

  • 4-2. Real-Time Translation

  • GPT-4o excels in real-time translation. It can understand and translate spoken language in real-time, taking into account tone and mood. This makes it a powerful tool for applications requiring real-time language translation, including live conversations, meetings, and presentations. GPT-4o's translation capabilities outperform previous models like Whisper-v3, especially in lower-resourced languages.

  • 4-3. Multilingual Support

  • The model achieves state-of-the-art performance in multilingual capabilities. This is evidenced by its high scores on benchmarks such as the M3Exam, which tests multilingual and vision understanding. GPT-4o uses fewer tokens across multiple languages, significantly improving efficiency. For example, it uses 3.3x fewer tokens for Tamil compared to previous models. It supports languages ranging from Gujarati to Japanese, providing extensive language coverage.

  • 4-4. Creative Projects

  • GPT-4o introduces a suite of creative capabilities including text generation, image creation, and audio outputs. It can be used for a variety of creative projects such as character design, poster creation, and poetic typography.
