Generative Pre-trained Transformer 4 (GPT-4) is a multimodal large language model trained and created by OpenAI and the fourth in its series of GPT foundation models. [1] It was launched on March 14, 2023, [1] and made publicly available via the paid chatbot product ChatGPT Plus, via OpenAI's API, and via the free chatbot Microsoft Copilot. [2]
GPT-4o has knowledge up to October 2023, [15] [16] but can access the Internet if up-to-date information is needed. It has a context length of 128k tokens [15] with an output token limit capped to 4,096, [16] and after a later update (gpt-4o-2024-08-06) to 16,384. [17]
For example, the GPT-4 Turbo model has a maximum output of 4096 tokens. [ 47 ] Length of a conversation that the model can take into account when generating its next answer is limited by the size of a context window, as well.
This figure seemed startlingly low compared to the more than $100 million that OpenAI said it spent training GPT-4, ... ($2.19 per million “tokens,” or segments of words outputted, versus $60 ...
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.

For many years, sequence modelling and generation was done by using plain recurrent neural networks (RNNs). A well-cited early example was the Elman network (1990). In theory, the information from one token can propagate arbitrarily far down the sequence, but in practice the vanishing-gradient problem leaves the model's state at the end of a long sentence without precise, extractable ...
So it introduced a formal parser to the mix, to check each token for legitimacy and reject it if it doesn’t work, demanding another one. That got the accuracy of the LLM’s coding ability up to ...
