What it shows

  • Production interactions yield continuous pairs of chosen vs rejected outputs.
  • Feedback sanitization filters spam and normalizes label bias automatically.
  • Direct Preference Optimization trains model policy without a reward model.

The takeaway

Capture continuous thumbs-up rankings in production to iteratively align LLM behavior via DPO.
