Notable quote:

'"Detecting and mitigating a model's logical mistakes, or hallucinations, is a critical step towards building aligned AGI [or artificial general intelligence]," Karl Cobbe, mathgen researcher at OpenAI, told CNBC, noting that while OpenAI did not invent the process-supervision approach, the company is helping to push it forward. "The motivation behind this research is to address hallucinations in order to make models more capable at solving challenging reasoning problems."'

As if hallucinations result from "logical mistakes" rather than from working exactly as designed and producing syntactically plausible continuations. And as if the problem is "solving challenging reasoning problems" as opposed to just having no notion of truth whatever and happily making stuff up. :P
