💡Batch size tweak drops RWKV PPL from 50 to 20 in hours—key for efficient training

⚡ 30-Second TL;DR

What Changed

Small effective batch=8 yields 50 PPL after 50k steps; stuck despite LR tweaks

Why It Matters

Simple tweak dramatically boosts training efficiency for RNN-based LMs like RWKV, potentially saving days of compute for practitioners.

What To Do Next

Increase gradient accumulation to 64+ when training RWKV or similar LMs from scratch.

Who should care:Developers & AI Engineers

Key Points

  • Small effective batch=8 yields 50 PPL after 50k steps; stuck despite LR tweaks
  • Gradient accumulation=64 (effective=128) drops PPL to 20 in 2-3 hours
  • Tested on ~192.8M RWKV v6 via custom code on RTX 4050
  • Applies to from-scratch LM training and fine-tuning
