GRT-30M-QA (MatterWaveAI/grt-30m-qa)
GRT-30M-QA (GRTForQuestionAnswering) is a 100% Native Rotational Extractive Question Answering Model (29,306,020 parameters, zero nn.Linear layers, zero nn.Conv1d layers) built on MatterWaveAI/grt-30m.
GRTForQuestionAnswering replaces traditional dense span projection layers (nn.Linear(hidden_size, 2)) with a 2-channel GRTCosineClassificationHead (qa_outputs) parameterized by planar-pair phase_angles ([2, 128]) and softplus radial pair_scales ([2, 128]), emitting start_logits and end_logits across context token positions.
8-Way Classical Geometric Optimizer Ablation (GRTForQuestionAnswering)
All 8 classical geometric optimizers in transformers.models.grt.optimization_grt were benchmarked under an identical 200-step adaptation protocol (seed = 42, batch_size = 24, backbone_lr = 1.8e-4) unfreezing the top rotational transformer block blocks[-1] (811,651 parameters), final_norm (128 parameters), and qa_outputs (523 parameters) for 812,430 total trainable parameters (0 nn.Linear):
