pfgen-bench - Chat Mode - Helpfulness: leaderboard

pfgen-bench (Preferred Networks) asks 50 Japanese questions expecting formal answers of about 100 characters and scores them without an LLM judge, averaged over trials; each metric is discounted linearly past 100 characters, to zero at 150. Chat mode: the instruction is a system prompt in a chat template. Helpfulness checks the answer for required keywords weighted by importance; higher is better.

Metric: Helpfulness Score. Source: github.com. Saturation forecast: Estimated already saturated. 35 models tracked.
