QK Gain Init 1.2 + Sliding Window Eval
Two orthogonal improvements over the naive baseline:
1. QK Gain Initialization (training)
QK_GAIN_INIT=1.2(default: 1.5) — better attention stability during short runs2. Sliding Window Evaluation (eval-only)
EVAL_STRIDE=64,EVAL_BATCH_SEQS=32— each token scored with 960+ tokens of contextforward_logits()andeval_val_sliding()functions (~70 lines)Local Results (RTX 4090, ~340 steps)
Looking forward to seeing H100 numbers from CI!
