MTP's multi-step prediction objective increases training memory overhead by approximately 15–25%, and requires careful tuning of the loss weights for each prediction head to avoid degradation of main-task performance.

UnverifiedMTP (multi-token prediction) adds extra prediction heads during training to predict multiple future tokens simultaneously in a single forward pass, requiring no separate draft model, but the candidate tokens lack autoregressive dependencies among them, so the acceptance rate is usually lower than that of dedicated speculative decoding methods.72% similarUnverifiedRetaining MTP capability during fine-tuning is a technical challenge, because if the training pipeline does not correctly handle the extra prediction head parameters, the weights of the MTP module will be corrupted or reset.72% similarUnverifiedOnly when a certain type of task is sufficiently high-frequency, stable, and cost-sensitive does migrating it from a general-purpose model to a specially trained model potentially realize significant cost benefits.71% similarUnverified分配给预训练的算力越多，下游任务的pass@1奖励就越高，预训练损失越低模型在后续RL中获得的收益越大70% similar
