What Is Spirit-v1.5
Spirit-v1.5 is an embodied intelligence foundation model launched by Qianxun Intelligence. The model adopts a diverse, open-ended data collection approach, abandoning the limitations of traditional "clean data" and allowing the model to be exposed to richer actions and scenarios during pretraining, giving it stronger generalization ability and adaptability. In the RoboChallenge real-robot evaluation, Spirit-v1.5 surpassed previous leading models with outstanding performance, becoming the current best embodied intelligence model and providing a new technical path and open-source benchmark for the development of embodied intelligence.
Main Features of Spirit-v1.5
-
Diverse Task Execution: Spirit-v1.5 can complete a variety of everyday tasks, such as flower arranging, putting fruit into baskets, hanging toothbrush cups, applying tape, and sweeping up trash.
-
Generalization Ability: Through diverse pretraining data, it has the ability to quickly adapt and execute tasks in unseen scenarios.
-
Robustness: It performs excellently in complex environments and can handle challenges such as object occlusion, lighting changes, and robotic arm coordination.
-
Support for Multiple Robot Platforms: The model is compatible with a variety of robot hardware, such as single-arm robots (Franka, UR5e) and dual-arm robots (ALOHA).
-
Efficient Fine-Tuning: It can be quickly fine-tuned on new tasks, reducing training time and resource consumption.
Technical Principles of Spirit-v1.5
-
Diverse Data Collection: The model abandons traditional "clean data" and adopts an open-ended, weakly controlled data collection approach. Collectors act freely around task goals, generating data that contains multiple atomic skills and real temporal relationships.
-
Pretraining and Fine-Tuning: The model is pretrained on large-scale diverse data to learn general strategies rather than the optimal solution for a single task. When fine-tuned on new tasks, the model can quickly adapt and perform excellently.
-
Vision-Language-Action (VLA) Model Architecture: It combines vision, language, and action modules, enabling the robot to understand natural language instructions, perceive the environment, and execute corresponding actions.
-
Reinforcement Learning and Self-Supervised Learning: The model uses reinforcement learning to optimize task success rates, while also improving the model's ability to adapt to environmental changes through self-supervised learning.
