Tensor Unveils OpenTau (τ) at CES 2026, Introducing a Breakthrough Open-Source Training Platform for Physical AI

Groundbreaking Release Advances Vision-Language-Action Foundation Models for Autonomous Driving, Robotics, and Embodied AI

LAS VEGAS, Jan. 8, 2026 /PRNewswire/ — At CES 2026, Tensor today announced the official open-source release of OpenTau (τ), a powerful AI training toolchain designed to accelerate the development of Vision-Language-Action (VLA) foundation models – a critical building block for the next generation of Physical AI systems.

At Tensor, we’re pushing the frontier of large foundation models for Physical AI. VLA models integrate vision, language, and action into a single multimodal foundation model, enabling intelligent systems to understand the world, reason about it, and act within it. This approach is increasingly recognized as a leading paradigm for Embodied AI, with applications spanning autonomous driving, robotic manipulation, and navigation.

OpenTau (τ) is Tensor’s open-source AI training platform for frontier VLA models, purpose-built to make large-scale AI training reproducible, accessible, and scalable. By releasing OpenTau to the global research and developer community, Tensor is making advanced training capabilities available beyond closed, proprietary environments—helping accelerate innovation across the industry. We believe the most meaningful technological advances are defined by clarity, rigor, and reproducibility. Open-sourcing is central to that philosophy, providing scientific transparency and enabling independent validation.

“At Tensor, we believe meaningful progress in Physical AI requires transparency,” said Jay Xiao, Founder and CEO of Tensor. “OpenTau is our way of giving back to the research and developer community that has helped advance this field. By open-sourcing our training toolchain, we’re supporting broader collaboration—so everyone can build, experiment, and move faster together..”

OpenTau brings state-of-the-art VLA training capabilities to the open-source community, including:

• Co-training on an adjustable mixture of heterogeneous datasets
• Discrete action modeling for faster Vision-Language Model (VLM) convergence
• Knowledge insulation between the VLM backbone and the action expert
• VLM dropout techniques to reduce overfitting
• A reinforcement learning pipeline purpose-built for Vision-Language-Action models
• And more

Designed with reproducibility and extensibility in mind, OpenTau enables researchers and developers to experiment with advanced training strategies that were previously difficult to implement or inaccessible outside of large-scale industrial research settings. We believe open research benefits the whole AI industry in the long run.

Tensor is inviting researchers, developers, and builders to explore OpenTau, contribute to its evolution, and help shape the future of Physical AI by starring the repository, forking and experimenting with the codebase, and building or extending frontier Vision-Language-Action models.
