I often feel the same way as you do when prompting, MathDeLux—the paradox between being “precise” and not “overwhelming” the model occupies my thoughts too. Sometimes it feels almost like a balancing act: if you provide too little context, you usually get something completely inconsequential; but if you pack in too much information or too many details, you end up with such vague asides that the model itself no longer knows what it is supposed to respond to. I’ve already noticed that language models like GPT-4 tend to “get lost” more quickly with complex tasks than with simpler prompts, which are easier to formulate anyway.
One observation from my sessions: there’s something like a “sweet spot.” Especially with longer prompts, structure and clarity suddenly become more important than the sheer number of words. I then try to organize things logically, as I would when programming—using sections, bullet points, or even short intermediate questions. Sometimes something as simple as this is enough: “First do x and then explain y; at the end, provide a summary in 1–2 sentences.” Personally, I even prefer that to a single, endlessly long prompt with everything written on one long line. Occasionally, I also specify exactly how detailed something should be (“briefly,” “a maximum of 5 sentences,” “bullet points only”)—and you can tell that models actually follow those instructions quite obediently as long as the structure remains understandable.
Something else I find interesting: the tone you use also has a massive impact on the result. A bit like with real people… For example, if I write a prompt along the lines of “Imagine you’re a teacher for 10-year-olds…,” I suddenly get answers that are much more vivid and easier to understand. Maybe there’s a little trick in there for guiding a kind of “expectation”—at least it often works better for me than simply providing data.
What still leaves me puzzled is why nonsense sometimes comes out despite using highly precise prompts. Last month, I had a conversation with GPT‑4o about quantum computers, fully referenced and including citations—yet some things were simply made up. 🤔 Maybe there are limits to prompt engineering that you simply can’t overcome?
