GPT-4o ("GPT-4 Omni") is a multilingual, multimodal generative pre-trained transformer designed by OpenAI. It was announced by OpenAI's CTO Mira Murati during a live-streamed demo on 13 May 2024 and released the same day.[1] GPT-4o is free, but with a usage limit that is 5 times higher for ChatGPT Plus subscribers.[2] Its API is twice as fast and half the price of its predecessor, GPT-4 Turbo.[1]

Background[edit]

GPT-4o was originally shadow launched on the Large Model Systems Organization (LMSYS) as 3 different models. These 3 models were called gpt2-chatbot, im-a-good-gpt2-chatbot, and im-also-a-good-gpt2-chatbot.[3] On 7 May 2024, Sam Altman tweeted "im-a-good-gpt2-chatbot", which was commonly interpreted as a confirmation that these were new OpenAI models being A/B tested.[4]

Capabilities[edit]

GPT-4o achieved state-of-the-art results in voice, multilingual, and vision benchmarks, setting new records in audio speech recognition and translation.[5][6] GPT-4o scored 88.7 on the Massive Multitask Language Understanding (MMLU) benchmark compared to 86.5 by GPT-4.[7] For voice-to-voice—unlike GPT-3.5 and GPT-4 which convert the voice to text, give the text to the model, then convert the text back to voice using another model—GPT-4o natively supports voice-to-voice making the response near instant and seamless.[7] Sam Altman noted on 15 May 2024 that GPT-4o's voice-to-voice capabilities were not yet integrated into ChatGPT, and that the old version was still being used.[8]

The model supports over 50 languages,[1] which OpenAI claims cover over 97% of speakers.[9] Mira Murati demonstrated the model's multilingual capability by speaking Italian to the model and having it translate between English and Italian during the live-streamed OpenAI demo event on 13 May 2024. In addition, the new tokenizer uses fewer tokens for certain languages, especially languages that are not based on the Latin alphabet, making it cheaper for those languages.[7]

GPT-4o has knowledge up to October 2023[10][11] and has a context length of 128k tokens[10] with output token limit capped to 2048.[11]

As of May 2024, it is the leading model in the Large Model Systems Organization (LMSYS) Elo Arena Benchmarks by the University of California, Berkeley.[12]
