Japanese GPT-NeoX 3.6B PPO

This model adds PPO reinforcement learning after Japanese GPT-NeoX 3.6B SFT v2. The alignment data uses a Japanese translation of an Anthropic HH-RLHF subset.

Alignment changes generation behavior

rinna reports that this PPO release repeats text more often than SFT v2. Its example uses a repetition penalty of 1.1. The comparison applies the same decoding settings to both checkpoints.Japanese GPT-NeoX 3.6B PPO official model card

Compare repetition as well as helpfulness

Practical guidance. Read a full long answer when comparing the two stages. An improved opening can hide repeated text later. Keep sampling settings fixed before attributing a difference to reinforcement learning.
