Why people are cross-checking

“I just take whatever Claude outputs, tell GPT to assess. Squashes 90% of hallucinations. But it's slow and cumbersome.”
— Solomon-Drowne, Reddit

“If you have to fact-check every claim anyway, why use an LLM to begin with?”
— Lost-Albatross, Reddit

“The hardest part isn't the prompts — it's answering ‘is this agent actually good?’ in production.”
— prateek63, Reddit
