This is a very informative post on LLM hallucinations and the SelfCheckGPT approach for mitigating them! The breakdown of the different consistency check methods (BERTScore, NLI, LLM Prompt) is particularly helpful, along with the real-world examples.

The discussion on the trade-offs between the different methods is insightful. While the LLM-Prompt approach seems most effective, it also requires additional LLM calls. This transparency regarding limitations is valuable for users considering implementing such methods.

Overall, a great exploration of a critical challenge in the LLM space!
