[7] OpenAI introduced the first GPT model (GPT-1) in 2018, publishing a paper called "Improving Language Understanding by Generative Pre-Training.
[17] It can now interact with users through spoken words and respond to images, allowing for more natural conversations and the ability to provide suggestions or answers based on photo uploads.
[18] To gain further control over GPT-4, OpenAI introduced the "system message", a directive in natural language given to GPT-4 in order to specify its tone of voice and task.
This allows the model to perform tasks beyond its normal text-prediction capabilities, such as using APIs, generating images, and accessing and summarizing webpages.
The article quoted a biophysicist who found that the time he required to port one of his programs from MATLAB to Python went down from days to "an hour or so".
[22][23] On May 13, 2024, OpenAI introduced GPT-4o ("o" for "omni"), a model that marks a significant advancement by processing and generating outputs across text, audio, and image modalities in real time.
GPT-4o exhibits rapid response times comparable to human reaction in conversations, substantially improved performance on non-English languages, and enhanced understanding of vision and audio.
GPT-4o achieves state-of-the-art results in multilingual and vision benchmarks, setting new records in audio speech recognition and translation.
Despite GPT-4's strong performance on tests, the report warns of "significant risks" of using LLMs in medical applications, as they may provide inaccurate recommendations and hallucinate major factual errors.
Sam Bowman, who was not involved in the research, said the results do not necessarily indicate a lack of abstract reasoning abilities, because the test is visual, while GPT-4 is a language model.
Second, human reviews are used to fine-tune the system in a process called reinforcement learning from human feedback, which trains the model to refuse prompts which go against OpenAI's definition of harmful behavior, such as questions on how to perform illegal activities, advice on how to harm oneself or others, or requests for descriptions of graphic, violent, or sexual content.
[50] According to their report, OpenAI conducted internal adversarial testing on GPT-4 prior to the launch date, with dedicated red teams composed of researchers and industry professionals to mitigate potential vulnerabilities.
[51] As part of these efforts, they granted the Alignment Research Center early access to the models to assess power-seeking risks.
Copilot is able to cite sources, create poems, and write both lyrics and music for songs generated by its Suno AI plugin.
Copilot X also provides terminal integration, which allows the user to ask GPT-4 to generate shell commands based on natural language requests.
[73] In January 2023, Sam Altman, CEO of OpenAI, visited Congress to demonstrate GPT-4 and its improved "security controls" compared to other AI models, according to U.S.
[20] Before being fine-tuned and aligned by reinforcement learning from human feedback, suggestions to assassinate people on a list were elicited from the base model by a red team investigator Nathan Labenz, hired by OpenAI.
[86] In the context of hours long conversation with the model, suggestions of love and dissolution of marriage, and murder of one of its developers were elicited from the Microsoft Bing's GPT-4 by Nathan Edwards (The Verge).
[91] (However, Melanie Mitchell has said [1]: "It seems that there is a lot more direction and hints from humans than was detailed in the original system card or in subsequent media reports.").
[96] Large language model (LLM) applications accessible to the public should incorporate safety measures designed to filter out harmful content.
[7][101] Sasha Luccioni, a research scientist at Hugging Face, argued that the model was a "dead end" for the scientific community due to its closed nature, which prevents others from building upon GPT-4's improvements.
[102] Hugging Face co-founder Thomas Wolf argued that with GPT-4, "OpenAI is now a fully closed company with scientific communication akin to press releases for products".
