Audio: Beyond just transcribing speech, GPT-4o understands tonal qualities, accents, multiple speakers, and even background sounds.
Video: While still developing, GPT-4o can process video inputs to understand both visual and audio components simultaneously.
This integrated understanding enables entirely new workflows. For example, users can point their phone camera at an object while speaking a question about it, and GPT-4o can analyze both inputs together to provide more relevant answers.
In educational contexts, GPT-4o can analyze a student showing their work on a math problem while explaining their thought process, providing much more targeted assistance than was previously possible.
How GPT-4o Improves Token Efficiency for Global Languages
One of GPT-4o's less flashy but highly significant improvements is its enhanced tokenization for non-English languages. Tokenization is the process of breaking text into smaller units (tokens) that AI models can process. More efficient tokenization means:
Lower costs (since API usage is billed per token)
Longer effective context windows
Better understanding of language nuances
GPT-4o's improvements are particularly dramatic for languages that use non-Latin scripts:
Language | Improvement | Example (Before → After) |
|---|---|---|
Gujarati | 4.4x fewer tokens | 145 → 33 tokens |
Telugu | 3.5x fewer tokens | 159 → 45 tokens |
Tamil | 3.3x fewer tokens | 116 → 35 tokens |
Marathi | 2.9x fewer tokens | 96 → 33 tokens |
Hindi | 2.9x fewer tokens | 90 → 31 tokens |
Arabic | 2.0x fewer tokens | 53 → 26 tokens |
Korean | 1.7x fewer tokens | 45 → 27 tokens |
Chinese | 1.4x fewer tokens | 34 → 24 tokens |
Japanese | 1.4x fewer tokens | 37 → 26 tokens |
Even European languages see modest improvements, with French, Spanish, and Italian all using approximately 10% fewer tokens.
This enhanced efficiency dramatically improves GPT-4o's utility for global users, making it more cost-effective and capable when working with non-English content.
