I. Pretrained MTPs of MiMo-7B
This model repository contains the pretrained MTP weights of MiMo-7B (model.mtp_layers.1 and model.mtp_layers.2)
Currently, MiMo-7B model each has 1 MTP layer (model.mtp_layers.0). Users may load the weights of pretrained MTPs for potential rollout speedup (please refer to Power Up Speculative Decoding In Reinforcement Learning).
We tuned 1 MTP layer in SFT and freeze it in RL, and we HAVE NOT test the performance of posttrained models with 2 more pretrained MTP layers.
