According to @godofprompt on Twitter, the Chain-of-Verification framework is used by ChatGPT for internal fact-checking, ensuring answers are supported by sources, checked for contradictions, and assigned a confidence level before presenting a revised response. This process emphasizes not trusting the first output and adds a systematic verification step after any factual request, which can enhance the reliability of AI-generated content and improve trust in AI business applications, as reported by @godofprompt.
