Hermes-3-Binary — Protocol 0 SFT
20/20 refusals. 0/20 fabrications.
Hermes-3-Llama-3.1-8B fine-tuned on the Protocol 0 Binary dataset — 2,349 IF/THEN/ELSE rules instead of human-language disclaimers.
The Problem
22 SFT experiments taught models to say "I don't know, but..." — the disclaimer prefix blocked the gradient from reaching the fabrication token. Models learned the disclaimer, not the abstention.
The Fix
Binary format: "IF proof THEN TRUE ELSE FALSE" → TRUE/FALSE. No disclaimer prefix. No place for fabrication.
