When ChatGPT summarises, it actually does nothing of the kind.

The author discusses their experience with using ChatGPT to summarize a complex paper on pension systems. They found that while ChatGPT could shorten the text, it did not effectively summarize the key points and proposals of the paper. The author suggests that this is because ChatGPT does not truly understand the content it is summarizing, but rather, it shortens the text based on its training data and the context of the prompts. The author concludes that ChatGPT's summarizing capabilities are limited and may not be reliable for real business uses.

Key takeaways

ChatGPT doesn't actually summarise text, it shortens it, which is a fundamentally different process requiring less understanding of the content.
The quality of a summary produced by ChatGPT is influenced by two key factors: the parameters from the training material and the context of the prompts and answers up to the point in the chat.
If the subject of the summary is well-represented in the training material, the parameters will dominate the summary. If the context is large and the subject isn't well-represented in the training material, the text to be summarised will dominate the result.
ChatGPT's inability to effectively summarise specific texts, especially those with pre-existing summaries, illustrates a fundamental lack of understanding in large language models.
