Researchers have introduced SmolVLA-MoE, a novel framework that enhances vision-language-action (VLA) models for robotic manipulation by incorporating a sparse Mixture-of-Experts (MoE) approach. This method replaces dense feed-forward network (FFN) layers with multiple expert FFNs and a router, allowing each token to dynamically select the most appropriate expert for action generation. SmolVLA-MoE activates only one expert FFN during inference, utilizing approximately 500 million activated parameters while benefiting from a total of 800 million stored parameters. Evaluations on the LIBERO benchmark demonstrated that SmolVLA-MoE achieved an 84.25% average success rate, surpassing existing models like SmolVLA and OpenVLA-7B in multi-task capability and efficiency.
