This is a curated list of "A Survey on Efficient Vision-Language Action Models" research.
To the best of our knowledge, this work presents the first comprehensive survey specifically dedicated to the realm of Efficient VLAs that covers the entire "data-model-training" process. We will continue to UPDATE this repository to provide you with the latest cutting-edge developments, so stay tuned!π We hope that our work will bring some inspiration to you~π

2026.08.23: Several recent papers on efficient VLA have been updated2026.06.18: Refreshed the paper lists and added recent robot-efficient-VLA papers, with an emphasis on model efficiency, adaptation efficiency, and data efficiency for robotic manipulation.2025.09.12: This repository was initialized.
Overview
Fig. 1: The Organization of Our Survey. We systematically categorize efficient VLAs into three core pillars: (1) Efficient Model Design, encompassing efficient architectures and model compression techniques; (2) Efficient Training, covering efficient pre-training and post-training strategies; and (3) Efficient Data Collection, including efficient data collection and augmentation methods. The framework also reviews VLA foundations, key applications, challenges, and future directions, establishing the groundwork for advancing scalable embodied intelligence.

Efficient Architectures
Fig. 2: Key strategies for Efficient Architectures in VLAs. We illustrate six primary approaches: (a) Efficient Attention, mitigating the O(n^2) complexity of standard self-attention; (b) Transformer Alternatives, such as Mamba; (c) Efficient Action Decoding, advancing from autoregressive generation to parallel and generative methods; (d) Lightweight Components, adopting smaller model backbones; (e) Mixture-of-Experts, employing sparse activation via input routing; and (f) Hierarchical Systems, which decouple high-level VLM planning from low-level VLA execution.

Model Compression
Fig. 3: Key strategies for Model Compression in VLAs. We illustrate three primary approaches: (a) Layer Pruning, which removes redundant layers to reduce model depth and computational cost; (b) Quantization, which reduces the numerical precision of model parameters to decrease memory footprint and accelerate inference; and (c) Token Optimization, which minimizes the number of processed tokens via token compression (merging tokens), token pruning (dropping non-essential tokens), and token caching (reusing static tokens).

Efficient Training
Fig. 4: Key strategies for Efficient Training in VLAs, divided into two main stages. (a) Efficient Pre-Training migrates general-purpose VLMs into the embodied domain to create an initial, action-aware policy, encompassing Data-Efficient Pre-training, Efficient Action Representation, and Other Pre-training Strategies. (b) Efficient Post-Training subsequently specializes this policy for specific tasks, leveraging Supervised Fine-tuning and RL-Based Methods.
