After months of anticipation for ChatGPT 5, OpenAI has instead released ChatGPT 4-o - a flagship AI model that can process audio, visuals, and text in real time. This development follows the massive success of ChatGPT 3, which fascinated users with its uncanny ability to understand and generate human-like text. While regular users can access the groundbreaking GPT-4o for free, ChatGPT Plus subscribers gain priority access to increased prompt limits and the latest multimodal features. Continue reading to learn more details about GPT-4o.

About ChatGPT- 4o

GPT-4o brings interactive human-computer communication by accepting inputs spanning text, audio and images while generating outputs across these same modalities. The latest AI model can respond to audio prompts in as little as 232 milliseconds, with an average response time of 320 milliseconds—nearly matching human response time. It matches GPT-4’s performance with English text and coding with a massive improvement in non-English language performance. And the best part is its ability to deliver much faster and 50% more cost-effective API access. However, its true strength lies in superior audio and visual comprehension compared to existing models.

Capabilities of ChatGPT- 4o

Before GPT-4o, users could use Voice Mode to talk to ChatGPT with latencies of 2.8 seconds (GPT-3.5) and 5.4 seconds (GPT-4) on average. To achieve this, previous versions of ChatGPT used a disconnected "Voice Mode" comprising three separate models: one transcribing audio to text, another (GPT-3.5 or GPT-4) processing that text, and a third converting the output text back to audio. This multi-step process resulted in informational losses for the core AI model, which could not directly perceive nuances like tone, multiple speakers, background noise, laughter, singing or emotional expression. Hence, GPT-4o integrates these modalities through an end-to-end training approach using a unified neural network architecture. With text, vision, and audio data flowing through a single model, ChatGPT-4o is a capable multimodal AI.

Language Tokenization of ChatGPT- 4o

To improve GPT-4o's linguistic capabilities, a new tokenizer was developed to process 20 diverse languages: Arabic, Bengali, Chinese, English, French, German, Gujarati, Hindi, Italian, Japanese, Kannada, Korean, Malayalam, Marathi, Oriya, Punjabi, Russian, Spanish, Tamil, and Telugu.

Model Evaluation of ChatGPT- 4o

On standard tests that measure text understanding, reasoning, and coding abilities, GPT-4o performs just as well as GPT-4 Turbo. However, GPT-4o sets new higher standards for understanding multiple languages, audio data like speech, and visual information like images. Check out the evaluation details below:

  • Text Evaluation: GPT-4o sets a new high score of 88.7% on the COT MMLU benchmark for general knowledge questions, showing improved reasoning abilities.
  • Audio ASR: GPT-4o dramatically improves speech recognition performance across all languages compared to Whisper-v3, especially for lower-resourced languages.
  • Audio Translation: GPT-4o establishes a new state-of-the-art on the MLS speech translation benchmark, outperforming Whisper-v3.
  • M3Exam Zero-Shot: On this multilingual and vision-based exam questions benchmark, GPT-4o outperforms GPT-4 across all languages.
  • Vision Understanding: GPT-4o achieves state-of-the-art performance on visual perception benchmarks like MMMU, MathVista, and ChartQA in zero-shot settings.

Safety Approach of ChatGPT- 4o

OpenAI has used robust safeguards in GPT-4o's core architecture across all modalities, like Meta’s LLama 3 and Microsoft’s Phi-3 using a responsible and safe AI approach. The model is built with techniques like filtered training data and post-training behavioural refinement to help imbue the model with built-in safeguards with novel systems to regulate voice outputs. The careful evaluations based on OpenAI's Preparedness Framework and voluntary commitments reveal that GPT-4o poses no higher than a "Medium" risk across categories like cybersecurity, CBRN (chemical, biological, radiological, and nuclear), persuasion, and model autonomy. This multi-stage assessment process involved comprehensive automated and human evaluations throughout training, testing pre- and post-mitigation versions using custom prompts and fine-tuning to probe the model's capabilities.

Over 70 external experts spanning social psychology, bias/fairness, and misinformation were engaged in extensive "red teaming" exercises to identify potential risks amplified by GPT-4o's multimodal nature. While OpenAI acknowledges the dangers presented by GPT-4o's audio capabilities, the current launch enables public access to text/image inputs and outputs. 

Model Availability of ChatGPT- 4o 

Thanks to OpenAI’s research of two years aiming to improve efficiency across the AI stack.  ChatGPT users can now leverage GPT-4o's text and image capabilities, with the model being offered on the free tier and up to 5x higher message limits for Plus subscribers. An alpha version of the revamped Voice Mode powered by GPT-4o will follow for ChatGPT Plus in the coming weeks. Developers can also now integrate GPT-4o for text and vision tasks via OpenAI's API, with a 2x performance boost, 50% cost reduction and 5x higher rate limits over GPT-4 Turbo. However, the support for GPT-4o's audio/video functions will initially roll out to a limited cohort of trusted partners in the coming weeks.

Conclusion 

As OpenAI continues to refine and expand the capabilities of ChatGPT-4o, we are eagerly waiting to experience breakthroughs in AI. At Hyperstack, we offer access to NVIDIA’s powerful resources such as the NVIDIA A100 and NVIDIA H100 PCIe, which boast exceptional performance and advanced features designed for accelerating powerful LLMs like GPT.
