> We should ask the LLM the question more than once

For any macOS users, I highly recommend an Alfred workflow so you just press command + space then type 'llm <prompt>' and it opens tabs with the prompt in perplexity, (locally running) deepseek, chatgpt, claude and grok, or whatever other LLMs you want to add.

This approach satisfies Fowler's recommendation of cross referencing LLM responses, but is also very efficient and over time gives you a sense of which LLMs perform better for certain tasks.
