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

GPT-4o was originally shadow launched on LMSYS, as 3 different models. These 3 models were called gpt2-chatbot, im-a-good-gpt2-chatbot, and im-also-a-good-gpt2-chatbot. On 7 May 2024, Sam Altman revealed that OpenAI was responsible for these mysterious new models.[3]

"Quantum Basics Explained"

Sure, let's break it down:
Basics of Quantum
1. Quantum means the smallest possible discrete unit of any physical property, like energy or matter.
2. Think of it like pixels in a digital image. Just as images are made up of tiny pixels, energy and matter are made up of tiny, indivisible units called quanta. Key Concepts
1. Particles and Waves: In the quantum world, particles like electrons can behave both as particles (little balls) and as waves (ripples in water). This is called wave-particle duality.
2. Uncertainty Principle: It's impossible to know both the exact position and exact momentum (speed and direction) of a particle at the same time. The more accurately you know one, the less accurately you can know the other.
3. Quantization: Energy levels in atoms are quantized, meaning electrons can only exist at specific energy levels. They can't exist in between these levels.
4. Superposition: Particles can be in multiple states at once. For example, an electron can be in two places at once until it is measured.
5. Entanglement: Particles can become entangled, meaning the state of one particle instantly influences the state of another, no matter how far apart they are.
Everyday Analogy Imagine a light switch that isn’t just on or off, but can exist in a state where it's both on and off at the same time until you look at it. This is somewhat like the idea of superposition.
Why It Matters Quantum mechanics explains the behavior of the smallest particles in the universe, which classical physics can't do. It's the foundation for modern technology like computers, lasers, and MRI machines.
In short, quantum mechanics is the science of the very small, where the usual rules of classical physics don't always apply.

– Output ChatGPT, GPT 4o model, given the prompt "Explain me quantum in simple terms."[4]

GPT-4o achieves state-of-the-art results in voice, multilingual, and vision benchmarks, setting new records in audio speech recognition and translation.[5] GPT-4o scores 88.7 on the Massive Multitask Language Understanding (MMLU) benchmark compared to 86.5 by GPT-4.[5] 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.[5] (Note: This feature hasn't been released yet, the voice feature in ChatGPT app is still the older version[6])

The model supports over 50 languages,[1] covering over 97% of speakers. 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.[5]

It is currently the leading model in the Large Model Systems Organization (LMSYS) Elo Arena Benchmarks by the University of California, Berkeley.[7]
