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.
While Microsoft's offerings make use of OpenAI's GPT-4 large language model, many others use a proprietary system. Meta AI, for example, is called LLaMA 3, which gathers information from a wide ...
Generative Pre-trained Transformer 3.5 (GPT-3.5) is a sub class of GPT-3 Models created by OpenAI in 2022. On March 15, 2022, OpenAI made available new versions of GPT-3 and Codex in its API with edit and insert capabilities under the names "text-davinci-002" and "code-davinci-002". [ 28 ]
Generative AI systems trained on words or word tokens include GPT-3, GPT-4, GPT-4o, LaMDA, LLaMA, BLOOM, Gemini and others (see List of large language models). They are capable of natural language processing, machine translation, and natural language generation and can be used as foundation models for other tasks. [62]
It took five years, for example, before AI systems surpassed humans on the ImageNet Large Scale Visual Recognition Challenge, established by Professor Fei-Fei Li and her team in 2010.
ChatGPT is a generative artificial intelligence chatbot [2] [3] 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. [4]
However, the company charges an additional monthly subscription to add Copilot to its Microsoft 365 suite of productivity applications, which includes Word, PowerPoint, and Excel.
According to Microsoft, this uses a component called the Orchestrator, which iteratively generates search queries, to combine the Bing search index and results [87] with OpenAI's GPT-4, [88] [89] GPT-4 Turbo, [90] and GPT-4o [91] foundational large language models, which have been fine-tuned using both supervised and reinforcement learning ...
