Few-Shot Example Curation: Quality, Rotation, and Counter-Examples, Part 1
Chain-of-thought prompts show real performance gains on reasoning tasks — and zero benefit on tasks that don't need reasoning. Here's how to tell which is which.
40 min · Reviewed 2026
The premise
Chain-of-thought is not a universal upgrade; it helps on reasoning-bound tasks and is overhead everywhere else.
What AI does well here
Use CoT on tasks requiring multi-step reasoning (math, complex logic, multi-constraint problems)
Use few-shot CoT examples on reasoning tasks where the structure of reasoning matters
Hide CoT from end-user output when the reasoning isn't user-facing value
Evaluate with and without CoT to confirm benefit on YOUR task
What AI cannot do
Make non-reasoning tasks better with CoT (it just adds tokens)
Make CoT a substitute for fine-tuning on hard reasoning tasks
Trust the reasoning trace as ground truth (models can produce plausible-but-wrong reasoning)
