GPT-4o (“o” for “omni”) is OpenAI’s latest flagship multimodal deep learning model that can process and generate information across text, audio, and image modalities simultaneously. It represents an advancement in AI technology, enabling more natural and intuitive human-computer interaction by being able to “see”, “hear”, and “speak” like humans. GPT-4o accepts as input and generates as output any combination of text, audio, and images, reasoning across these modalities in real-time within a single end-to-end neural network architecture.
While GPT-4o will be widely accessible, it is not “open” or “open source” (open for public modification and distribution), but rather available under controlled access through OpenAI’s platforms and services.
Compared to previous versions like GPT-3.5 and GPT-4, GPT-4o offers several features and improvements:
- Multimodality: GPT-4o can understand and respond to any combination of text, audio, and images, while previous models were primarily text-based and required separate pipelines for different input types.
- Real-Time Interaction: With an average response time of 320 milliseconds (as low as 232ms) for audio inputs, GPT-4o can converse naturally, closely matching human response times. This is a significant improvement over the latency experienced in Voice Mode with older GPT models (2.8s for GPT-3.5, 5.4s for GPT-4).
- Enhanced Performance: GPT-4o matches GPT-4 Turbo’s performance on text in English, coding, and reasoning tasks while exhibiting superior multilingual capabilities, especially in non-English languages. It also excels in audio and vision understanding compared to existing models.
- Cost and Speed: GPT-4o is 50% cheaper and twice as fast as GPT-4 Turbo within the API.
- End-to-End Architecture: A single neural network processes all inputs and outputs, eliminating information loss inherent in previous pipeline-based approaches.
Gemini 1.5 and GPT-4o
Google’s Gemini 1.5 and GPT-4o both represent advancements in multimodal AI, but they differ in their core capabilities and focus. GPT-4o excels in real-time, end-to-end multimodal processing, integrating text, audio, and images simultaneously with multilingual support and faster response times. In contrast, Gemini 1.5 emphasizes long-context understanding, handling up to 10 million tokens and excelling in long-form video analysis, making it highly effective for extensive document and video QA tasks. Both models push the boundaries of AI, but their strengths cater to different application needs and user expectations.
GPT-4o’s reign as the premier model will be short-lived
Examples provided by OpenAI
1. Two GPT-4os interacting and singing, highlighting the model’s ability to understand and generate audio, even composing and performing music collaboratively.
- Possible Applications: Revolutionizing music creation, generating personalized soundtracks for videos and games, creating interactive audio experiences in museums and exhibitions.
2. Visual Narratives, where GPT-4o processes both textual and visual inputs to create a dynamic narrative. A user provides text input describing a scene, and the model generates a corresponding visual output.
- Possible Applications: Creating storyboards for films and animations, generating illustrations for children’s books in real-time, assisting designers in prototyping product visuals based on textual descriptions, enhancing chatbots and virtual assistants to better understand and react to user input and context.
Current Limitations
- GPT-4o is still in the early stages of exploring its full potential and understanding its boundaries, particularly in areas such as observing tone, handling multiple speakers, and expressing emotions effectively.
- It can sometimes underperform compared to GPT-4 Turbo on certain tasks, requiring further research and development to address these performance gaps.
- The addition of new modalities introduces novel risks that require ongoing mitigation and the development of robust safety measures.
- Audio outputs are currently limited to preset voices and adhere to existing safety policies to mitigate potential misuse.
- Limited availability of audio and video capabilities at present.
Next Steps
OpenAI is gradually releasing GPT-4o’s capabilities, with text and image processing currently available in ChatGPT and the API. The company plans to launch audio and video capabilities to a small group of trusted partners soon, followed by a full release after thorough testing and infrastructure development to ensure user safety and usability. OpenAI is committed to ongoing development, testing, and iteration to explore the model’s full potential, improve safety and security, and address performance gaps. As the model becomes available to a wider range of users and developers, the company will seek feedback to identify areas for improvement.
Initial Reactions from Developers
The release of GPT-4o has generated a mix of positive and negative sentiments among developers. On the positive side, the model’s enhanced tokenizer and multilingual performance, human-like conversation capabilities, search functionality, improved efficiency, and multimodal capabilities have been widely praised. Developers see great potential in GPT-4o for creating engaging, immersive, and cost-effective AI applications across various domains, including language learning and real-time translation.
However, some concerns have also been raised, such as the potential for misuse and negative social impact, technical issues like hallucinations and latency, the uncanny valley effect of emotional inflection, and possible limitations in training data. These concerns underscore the importance of responsible AI development and the need for ongoing improvements in model performance and data sourcing.
GPT-4o’s reign as the premier model will be short-lived. The sheer pace of innovation in the field suggests that other players, both proprietary model providers like Google and Anthropic, and the burgeoning open model community, are hot on OpenAI’s heels. The race to achieve true multimodal AI mastery is a marathon, not a sprint, and GPT-4o’s impressive capabilities are merely a snapshot of the rapidly evolving landscape. With the open model initiatives gaining momentum, it’s highly probable that we’ll witness a Cambrian explosion of multimodal AI models, each pushing the boundaries of what’s possible and eroding GPT-4o’s early lead. This fierce competition promises to usher in an era of unprecedented progress and accessibility in AI.
