GPT-4o

What’s in the news?

OpenAI introduced its latest large language model (LLM) called GPT-4o recently billing it as their fastest and most powerful AI model so far. The company claims that the new model will make ChatGPT smarter and easier to use.
Until now, OpenAI’s most advanced LLM was the GPT-4, which was only available to paid users. However, the GPT-4o will be freely available.

What is GPT-4o?

GPT-4o is being seen as a revolutionary AI model, which has been developed to enhance human-computer interactions.
“o” stands for “Omni”.
It lets users input any combination of text, audio, and image and receive responses in the same formats. This makes GPT-4o a multimodal AI model.
GPT-4o is capable of interacting using text and vision, meaning it can view screenshots, photos, documents, or charts uploaded by users and have conversations about them.
The updated version of ChatGPT will also have updated memory capabilities and will learn from previous conversations with users.

Technology behind GPT-4o

Large Language Models are the backbone of AI chatbots.
Large amounts of data are fed into these models to make them capable of learning things themselves.

Comparison with the previous models

GPT 4o	Predecessor Models
GPT-4o uses a single model trained end-to-end across various modalities – text, vision, and audio.	Earlier models required multiple models to handle different tasks. For example, the voice mode is a combination of three different models – transcription, intelligence, and text-to-speech.
GPT-4o comes with an integration that allows it to process and understand inputs more holistically. For example, GPT-4o can understand tone, background noises, and emotional context in audio inputs at once.	These abilities were a big challenge for earlier models.
Features and abilities: GPT-4o excels in areas like speed and efficiency as it responds to queries as fast as a human does in conversation, in around 232 to 320 milliseconds.	Previous models were slower and came with response times of up to several seconds.
It comes with multilingual support, and shows significant improvements in handling non-English text, making it more accessible to a global audience. The GPT-4o also features enhanced audio and vision understanding.

When will GPT-4o be available?

GPT-4o will be made available to the public in stages.
- Text and image capabilities are already present on ChatGPT, with some services available to free users.
- Audio and video functionalities will come gradually to developers and selected partners, ensuring that each modality (voice, text-to-speech, vision) meets the necessary safety standards before full release.

GPT-4o’s limitations

GPT-4o is still in the early stages of exploring the potential of unified multimodal interaction, meaning certain features like audio outputs are initially accessible in a limited form only, with preset voices.
Further development and updates are necessary to fully realise its potential in handling complex multimodal tasks seamlessly.
