Generative Pre-trained Transformer 2 (GPT-2) is a large language model by OpenAI and the second in their foundational series of GPT models. GPT-2 was pre-trained on a dataset of 8 million web pages. [2] It was partially released in February 2019, followed by full release of the 1.5-billion-parameter model on November 5, 2019. [3] [4] [5]
Generative Pre-trained Transformer 2 ("GPT-2") is an unsupervised transformer language model and the successor to OpenAI's original GPT model ("GPT-1"). GPT-2 was announced in February 2019, with only limited demonstrative versions initially released to the public.
OpenAI's GPT-n series Model Architecture Parameter count Training data Release date Training cost GPT-1: 12-level, 12-headed Transformer decoder (no encoder), followed by linear-softmax. 117 million BookCorpus: [39] 4.5 GB of text, from 7,000 unpublished books of various genres. June 11, 2018 [9] 30 days on 8 P600 graphics cards, or 1 petaFLOPS ...
Google currently holds nearly 90 per cent of the global search engine market share, with recent efforts by Microsoft to integrate AI into its Bing search failing to make a dent.
The language model has 175 billion parameters — 10 times more than the 1.6 billion in GPT-2, which was also considered gigantic on its release last year. GPT-3 can perform an impressive range of ...
In 2019 October, Google started using BERT to process search queries. [36] In 2020, Google Translate replaced the previous RNN-encoder–RNN-decoder model by a Transformer-encoder–RNN-decoder model. [37] Starting in 2018, the OpenAI GPT series of decoder-only Transformers became state of the art in natural language generation.
Evaluations of controlled LLM output measure the amount memorized from training data (focused on GPT-2-series models) as variously over 1% for exact duplicates [141] or up to about 7%. [ 142 ] A 2023 study showed that when ChatGPT 3.5 turbo was prompted to repeat the same word indefinitely, after a few hundreds of repetitions, it would start ...
Microsoft on Tuesday debuted a host of new AI features during its Build conference in Seattle, including OpenAI’s new GPT-4o, a trio of small language models, and Microsoft’s new Cobalt 100 CPU.
