ChatGPT is a generative artificial intelligence chatbot developed by OpenAI and launched in 2022. It is currently based on the GPT-4o large language model (LLM). ChatGPT can generate human-like conversational responses and enables users to refine and steer a conversation towards a desired length, format, style, level of detail, and language. [2]
Generative Pre-trained Transformer 3 (GPT-3) is a large language model released by OpenAI in 2020.. Like its predecessor, GPT-2, it is a decoder-only [2] transformer model of deep neural network, which supersedes recurrence and convolution-based architectures with a technique known as "attention". [3]
Ernie Bot is based on particular Ernie foundation models, including Ernie 3.0, Ernie 3.5, and Ernie 4.0. The training process starts from pre-training, learning from trillions of data points and billions of knowledge pieces. This was followed by refinement through supervised fine-tuning, reinforcement learning with human feedback, and prompt. [19]
GPT-4o ("o" for "omni") is a multilingual, multimodal generative pre-trained transformer developed by OpenAI and released in May 2024. [1] GPT-4o is free, but ChatGPT Plus subscribers have higher usage limits. [2]
A large language model (LLM) is a type of machine learning model designed for natural language processing tasks such as language generation.LLMs are language models with many parameters, and are trained with self-supervised learning on a vast amount of text.
Prompt engineering is the process of structuring or crafting an instruction in order to produce the best possible output from a generative artificial intelligence (AI) model. [1] A prompt is natural language text describing the task that an AI should perform. [2]
Generative pretraining (GP) was a long-established concept in machine learning applications. [16] [17] It was originally used as a form of semi-supervised learning, as the model is trained first on an unlabelled dataset (pretraining step) by learning to generate datapoints in the dataset, and then it is trained to classify a labelled dataset.
It announced Sora, a text-to-video model intended to create realistic videos from text prompts, and available to ChatGPT Plus and Pro users. [ 113 ] [ 114 ] Additionally, OpenAI launched the o1 model, which is designed to be capable of advanced reasoning through its chain-of-thought processing, enabling it to engage in explicit reasoning before ...
