OpenAI’s GPT-2 language model has amazing text generation capabilities. It can generate coherent articles, write computer code, and create art.
GPT-2 is pre-trained on a massive text corpus of 40GB. It uses the Transformer architecture (as opposed to RNN, LSTM, or GRU).
Wired tested out GPT-2 and gave it the prompt “Hillary Clinton and George Soros”. The result was the kind of political conspiracy nonsense you see on non-credible right-wing websites.
What is GPT-2 AI article
GPT-2 is basically the decoder part of a regular transformer network. It can be trained to generate text for a variety of tasks, such as translations, question answering, summarizing passages and writing articles. It does this by interpreting an encoded sequence of words and then generating a new one word by word.
This makes it very different from other NLP models such as RNN, LSTM, or GRU, which are trained to do specific tasks like image recognition. OpenAI’s goal with GPT-2 was to create a single model that could be fine-tuned for different applications.
So far, the results have been pretty impressive. GPT-2 can generate text that is almost indistinguishable from humans and even answer questions about a topic it has been given. The only downside is that it often reflects societal biases, such as the tendency for men to work in higher-paying jobs.
How does GPT-2 generate articles
GPT-2 is the latest iteration of an artificial intelligence system that can generate text. The system uses a large database of words and phrases to create articles that are indistinguishable from those written by humans. It is a big step forward from previous AI systems, such as ELIZA, that used a limited database to mimic human conversation and answer questions.
GPT- 2, which stands for “Generative Pretrained Transformer 2”, was developed by OpenAI in February 2019. It is a language model that can generate text by predicting the next word based on a given sentence. It is trained on massive amounts of data from all over the internet and outperforms state-of-the-art models in text generation. It also has a unique feature that allows it to pretrain one-directional representations, unlike previous machine learning models.
Despite its impressive performance, the team behind GPT-2 was concerned about its potential for abuse. A blog post by the company worried that it could be used to create fake news articles or spam the internet with vitriol. The team decided to release a much smaller version of the model out of fear that it would be used for malicious purposes.
The new model has been very popular among developers. One example is a Python notebook by Neil Shepperd that allows users to fine-tune the model on custom datasets. It can be downloaded from GitHub and is designed to run on Google’s Colaboratory service, which provides a free GPU.
Can GPT-2 create realistic articles
GPT-2 is a powerful AI tool that can create realistic articles that look and read like the originals. It uses a technique called language modeling, which is similar to how predictive text works on your phone. The model internalizes a statistical blueprint of the language and is able to select words that are most likely to follow. This allows it to mimic the style of a particular writer. In some cases, the results are so convincing that it’s hard to tell the difference between the AI article and the real thing.
While GPT-2 has the ability to create highly realistic articles, it does have its limitations. For one, it cannot understand concepts that are beyond its training corpus, such as space, time, and causality. It can only predict words based on their probability of appearing next, and cannot infer that they have a certain meaning.
However, it can still be used for many useful purposes, such as generating natural language responses to customer service inquiries or generating article titles. And with the recent success of efforts to fine-tune GPT-2, it may be able to become even more useful in the future. Hopefully, people will be able to use it responsibly and not for malicious purposes. As with any new technology, there is always a risk of it being abused or misused. But I think if we use it responsibly, GPT-2 can have a positive impact on the world.
Is GPT-2 trained on real articles
GPT-2 is a large language model that can generate realistic text in a variety of styles based on some seed data. Its ability to do so is a significant achievement in natural language processing (NLP) that has raised eyebrows and excitement. However, when OpenAI initially announced this model, it opted not to publish the full parameters of the model because of concerns that it could be used for malicious purposes.
In a blog post, the company noted that if GPT-2 was made available to malicious actors, it could be used to create and distribute vast amounts of bile and hatred online. It also worried that the model could be used to flood social media with spam and influence debate online. While humans can already do this, GPT-2 would be able to do it on a much larger scale and with greater speed.
Many researchers have criticised the decision by OpenAI to withhold the model, with Vanya Cohen, a master’s graduate student from Brown University, saying that withholding the model will slow down countermeasure research. Other critics point out that GPT-2 is not as advanced as it’s being portrayed, with its ability to generate text in a Buzzfeed-style being an example. It can produce some titles that fit the aesthetic, but not all of them do – and it can’t maintain a reasonable level of coherence when writing longer pieces.
What are the limitations of GPT-2
GPT-2 is an impressive model. The fluent sentences it generates can sometimes give the appearance of intelligence (though GPT-2 is not doing anything that we would recognize as cognition). It is able to perform well in a variety of tasks, including writing news articles and even generating code from a single sentence.
GPT-2 has several strengths, but it is not without its limitations. For example, it struggles to write long-term coherent stories. This is due to its inability to track recurring themes and characters over time. It can only predict words at a word level, which is not enough to track the occurrence of themes in a story or to hold a conversation.
In addition to its problems with long-term coherence, GPT-2 can also struggle to answer simple factual questions. For example, it often fails to correctly guess that an eclipse is the same as a solar eclipse.
The model is also prone to creating repetitive text and misunderstands specialized topics. While this is to be expected from any natural language generation algorithm, it is still a problem that needs to be addressed.
While many have criticized OpenAI’s decision not to release the model, others have argued that withholding it is counterproductive. Vanya Cohen, a master’s student at Brown University, recently recreated the GPT-2 model and has been able to fine-tune it to produce high quality articles on any topic. He encourages others to use the model and says that he hopes that it will be used for good, not evil.
Can GPT-2 replace human writers
GPT-2’s ability to generate coherent, well-written text is astounding. The system is able to produce writing that feels almost human, and can generate articles about a topic with little to no guidance from humans. In fact, the only thing that GPT-2 requires to perform these tasks is a massive dataset of text from around the internet. To create this dataset, researchers used Reddit to filter links, scraped 8 million pages from the web, and then trained the model on these results. This data gave GPT-2 an amazing ability to predict words and phrases, which is what makes the model so successful at language modeling tasks.
GPT-2 isn’t perfect, however. It still struggles with long-term coherence, and it can’t hold a conversation. Despite these limitations, it’s clear that the technology is advancing quickly, and will eventually allow computers to produce a lot of useful content, from novels to news articles.
Unfortunately, there is always a risk that these advances will be misused to make malicious content. In a world where information warfare is common, the idea of AI programs that can spit out endless amounts of cogent fake news or propaganda is unsettling. That’s why OpenAI is taking a cautious approach with the release of GPT-2. It has released a smaller version of the model, and will only share it through research partnerships. It has also released the Python code and a TensorFlow file that can be used to run GPT-2’s predictions on your own machine.
