Strong performance. LION achieves state-of-the-art performance on Waymo, nuScenes, Argoverse V2, and ONCE datasets. 💪
-
Strong generalization. LION can support almost all linear RNN operators including Mamba, RWKV, RetNet, xLSTM, and TTT. Anyone is welcome to verify more linear RNN operators. 😀
-
More friendly. LION can train all models on less 24G GPU memory~(i.e., RTX 3090, RTX4090, V100 and A100 are enough to train our LION) 😀
- 2024.07.25: LION paper released. 🔥
- 2024.07.02: Our new works OPEN and SEED have been accepted by ECCV 2024. 🎉

- We provide some examples of LION models on KITTI dataset for quick validation of any Linear RNN operators.
- Here, we provide the results of moderate difficulty for LION with RetNet, RWKV, Mamba, xLSTM, and TTT.
- Anyone is welcome to verify more linear RNN operators. 😀
