# GPT-4o: OpenAI’s flagship multimodal model

**GPT-4o** ("omni") is OpenAI's flagship multimodal model, designed to natively integrate the fluid understanding and generation of text, vision, audio and video with minimal latencies.

## Omni Unified Neural Architecture

Unlike previous systems that chained independent models for transcription, reasoning, and speech synthesis, GPT-4o was trained end-to-end through a single neural network. This allows you to capture voice intonations, pauses, audio emotions, and instant visual details.

### Ultra Low Latency

232ms

Audio response time similar to a fluid human conversation.

### MMLU Benchmark

88.7%

Outperforms traditional GPT-4 in reasoning and general knowledge.

### Multilingual

50+ Languages

Tokenization compression optimized for speed in Spanish and non-English languages.

## Availability in OpenAI Plans and Ecosystem

GPT-4o is available for both ChatGPT Plus, Team and [ChatGPT Pro](https://comunicagenia.com/en/blog/chatgpt-pro-at-200-a-month-do-you-really-need-it/) users, as well as for users of the free tier with dynamic usage quotas. For developers, it is offered via API with costs 50% lower than GPT-4 Turbo.
