Details
OpenAI has announced GPT-4o, a new flagship model capable of processing text, audio, vision, and images together in real time. The 'o' stands for 'omni,' and the model aims for natural interaction at a level similar to humans.
The existing Voice Mode was a pipeline approach that passed through three separate models for speech recognition, text processing, and speech synthesis, but GPT-4o is an end-to-end model that processes all modalities within a single neural network. This allows it to directly understand and generate tone of voice, background noise, emotional expression, and more.
Key features include the following:
- Real-time response: Achieves an average response speed of 320ms, showing a level similar to human conversation speed.
- Performance and efficiency: English text and code performance is on par with GPT-4 Turbo, while performance in non-English languages has significantly improved. In addition, API costs are 50% cheaper and speed is faster.
- Multimodal capabilities: Can take text, audio, image, and video as input and output a combination of text, audio, and image.
