GPT-4o: Revolutionising AI Interaction with Seamless Integration of Text, Audio, and Vision Capabilities
OpenAI has introduced its new flagship model, GPT-4o, which integrates text, audio, and visual inputs and outputs to make machine interactions feel more natural.
GPT-4o, with “o” standing for “omni,” supports a broad range of input and output formats. “It can handle any mix of text, audio, and image inputs and produce any combination of text, audio, and image outputs,” OpenAI stated.
The model promises rapid response times, as quick as 232 milliseconds, closely matching human conversational speed, and an average response time of 320 milliseconds.
Pioneering Capabilities
GPT-4o represents a significant advancement over its predecessors by processing all types of inputs and outputs through a single neural network. This unified approach helps retain critical context and information that was previously lost with separate model pipelines in earlier versions.
Earlier models like GPT-3.5 and GPT-4’s ‘Voice Mode’ managed audio interactions with delays of 2.8 seconds and 5.4 seconds, respectively. They used three different models: one for transcribing audio to text, another for generating text responses, and a third for converting text back to audio. This fragmented process often missed nuances like tone, multiple speakers, and background noise.
With its integrated approach, GPT-4o excels in vision and audio understanding, enabling it to perform more complex tasks such as harmonising songs, offering real-time translations, and generating outputs with expressive elements like laughter and singing. Its versatile capabilities include preparing for interviews, translating languages on the go, and generating customer service responses.
Nathaniel Whittemore, Founder and CEO of Superintelligent, remarked, “Product announcements tend to be more divisive than technology announcements because it’s hard to judge a product’s uniqueness without firsthand experience. Especially with new modes of human-computer interaction, opinions vary widely on their usefulness.
“However, the absence of a GPT-4.5 or GPT-5 announcement distracts from the technological leap this model represents as a natively multimodal model. It’s not just a text model with voice or image additions; it processes multimodal tokens both in and out. This opens up a vast range of new use cases that will take time to fully appreciate.”
Performance and Safety
GPT-4o matches GPT-4 Turbo in performance for English text and coding tasks but surpasses it in non-English languages, making it a more inclusive and versatile model. It sets new standards in reasoning with a high score of 88.7% on 0-shot COT MMLU (general knowledge questions) and 87.2% on the 5-shot no-CoT MMLU.
The model also excels in audio and translation benchmarks, outperforming previous top models like Whisper-v3. In multilingual and vision evaluations, it shows superior performance, enhancing OpenAI’s capabilities in these areas.
OpenAI has built robust safety measures into GPT-4o, incorporating techniques to filter training data and refine behaviour through post-training safeguards. The model has been evaluated through a Preparedness Framework and complies with OpenAI’s voluntary commitments. It has been assessed for risks in cybersecurity, persuasion, and model autonomy, with no category exceeding a ‘Medium’ risk level.
Further safety evaluations involved extensive external red teaming with over 70 experts in fields such as social psychology, bias, fairness, and misinformation. This thorough scrutiny aims to mitigate risks from the new capabilities of GPT-4o.
Availability and Future Integration
Starting today, GPT-4o’s text and image features are available in ChatGPT, including a free tier and additional features for Plus users. A new Voice Mode powered by GPT-4o will begin alpha testing in ChatGPT Plus in the coming weeks.
Developers can access GPT-4o through the API for text and vision tasks, benefiting from its doubled speed, halved price, and increased rate limits compared to GPT-4 Turbo.
OpenAI plans to extend GPT-4o’s audio and video functionalities to select trusted partners via the API, with a broader rollout anticipated soon. This phased release strategy ensures thorough safety and usability testing before the full capabilities are made publicly available.
“It’s hugely significant that they’ve made this model available for free to everyone, as well as making the API 50% cheaper. That is a massive increase in accessibility,” explained Whittemore.
OpenAI encourages community feedback to continuously improve GPT-4o, highlighting the importance of user input in identifying and addressing areas where GPT-4 Turbo might still have an edge.
