How Was ChatGPT Trained?
The development of ChatGPT, a language model by OpenAI, involved a unique training approach to increase its positive impact on users. Instead of only optimizing the next word prediction, the AI was trained with human feedback, a process called Reinforcement Learning with Human Feedback. This training allowed ChatGPT to understand human intent and provide helpful, truthful, and harmless answers. A comparison between ChatGPT and its sibling model, GPT-3, showed that ChatGPT received higher ratings from contractors for truthfulness and showed small improvements in toxicity. However, there is still room for improvement in terms of safety and reliability.
Another research paper demonstrated how AI was trained to summarize information from Reddit posts and news articles by predicting what humans preferred. The AI was trained using a dataset of human comparisons between different answers, which allowed the machine to become better at predicting satisfactory answers. The research showed that it was possible to significantly improve summary quality by optimizing for human preferences.
What are the Limitations of ChatGPT?
ChatGPT is a language model created by OpenAI that is designed to interact and respond to questions in a conversational manner. While it has the potential to provide human-like answers, there are several limitations to its responses.
One limitation is that ChatGPT is programmed to avoid providing harmful or toxic answers, but the quality of the response will depend on the quality of the input. This means that expert prompts result in better answers.
Another limitation is that ChatGPT can sometimes provide incorrect answers that appear to be correct. For example, the coding Q&A website Stack Overflow was overwhelmed with a large number of ChatGPT-generated answers that appeared correct, but many of them were actually incorrect. The administrators at Stack Overflow had to enact a temporary ban on the use of ChatGPT on the site.
OpenAI has acknowledged these limitations and has explained that there are challenges to fixing the issue, such as the lack of a source of truth during the training process, the difficulty in training the model to be more cautious, and the misleading nature of supervised training.
Is ChatGPT Free To Use?
The creation of ChatGPT, a language model developed by OpenAI, involved an innovative method of training to ensure it provides the best possible outcomes for its users. Rather than simply optimizing the next word prediction, the AI was trained through Reinforcement Learning with Human Feedback, which allowed it to understand the intended meaning behind a question and provide helpful, truthful and non-harmful answers. Comparison tests with GPT-3, a sibling model of ChatGPT, showed that ChatGPT was favored for truthfulness, with small improvements in reducing toxicity. Despite these positive results, further improvements are still needed for the AI to be completely safe and reliable.
Another study focused on training AI to summarize information from sources such as Reddit posts and news articles. The AI was trained to predict what answers would be preferred by humans, using a dataset of comparisons between different answers. The results of the study showed that by optimizing for human preferences, the AI was able to significantly improve the quality of the summaries it produced.
