Gemini 2.0 Flash
Gemini 2.0 Flash is natively multimodal from inception across text, high-resolution audio, vision, and video. It delivers sub-second time-to-first-token latency, native bidirectional audio streaming, and seamless integration with external search grounding and code execution.
GPT-4o (Omni)
GPT-4o trains a single neural network end-to-end across text, vision, and audio, preserving emotional inflections, background acoustics, and conversational interruptions that were lost in cascaded voice pipelines.
