If you’re a frequent user of ChatGPT, you know the tendency it has to wander off into what is known as hallucinations. A great collection of statistically correct words that have no basis in reality. A few months ago, a prompt about using Apache Cassandra for large language models (LLMs) and LangChain resulted in a curious response. ChatGPT reported that not only was Cassandra a good tool choice when creating LLMs, but OpenAI used Cassandra with an MIT-licensed Python library they called CassIO. Into the rabbit hole we went, and through more prompting, ChatGPT described many details about how CassIO was used. It even included some sample code and a website. Subsequent research found no evidence of CassIO outside of ChatGPT responses, but the seed was sown. If this library didn’t exist, it needed to, and we started work on it shortly after.
Best hallucination ever.
