PLEASE SEARCH RLDX-1 IN "PROFESSIONAL SERVICE" FOR FURTHER IMPLEMENTATION
RLDX-1 is a general-purpose robotics foundation model (RFM) built on a "Dexterity-First" philosophy - engineered from the ground up to give high-DoF robotic hands human-level dexterous manipulation. Unlike conventional Vision-Language-Action (VLA) models that reason primarily over what a robot sees and hears, RLDX-1 also processes torque, tactile feedback, and working memory within a single model. This is powered by its Multi-Stream Action Transformer (MSAT) architecture, which assigns independent streams to each modality - vision, language, action, force, and memory - and fuses them through joint attention, enabling robots to see, feel, remember, and adapt in dynamic, contact-rich environments.
RLDX-1 delivers state-of-the-art performance across eight public robotics benchmarks. It scored 70.6 on RoboCasa Kitchen and 58.7 on GR-1 Tabletop-both surpassing NVIDIA's GR00T N1.6 - and reached 86.7% on LIBERO-Plus, which stress-tests robustness across lighting and camera variations. In real-world hardware testing on WIRobotics' ALLEX humanoid, RLDX-1 completed a contact-rich pot-to-cup pouring task with a 70.8% success rate, roughly double that of comparable models. Notably, it achieves this using approximately 20% of the training compute of NVIDIA GR00T N1.5, reflecting the strength of its architecture and data engine rather than sheer scale.
Designed for real-world industrial deployment, RLDX-1 runs across single-arm, dual-arm, and humanoid embodiments with high-DoF hands, and has been validated on platforms including WIRobotics ALLEX, Franka Research 3, and OpenArm. It spans the complete robotics lifecycle - from a scalable data-collection pipeline combining teleoperation, synthetic, and human data, through training and optimized deployment - for tasks such as grasping, pouring, tool use, and assembly across manufacturing, logistics, retail, and service settings. Built on the NVIDIA robotics and AI stack, RLDX-1 is the foundation for dexterous automation at scale.
Highlights
Dexterity-first, beyond vision and language. Unlike conventional Vision-Language-Action (VLA) models, RLDX-1 is a robotics foundation model that also processes torque, tactile feedback, and working memory in a single Multi-Stream Action Transformer (MSAT) - so robots don't just see and talk, but feel, remember, and adapt to master contact-rich dexterous manipulation like grasping, pouring, and tool use.
State-of-the-art performance at a fraction of the compute. RLDX-1 leads eight public robotics benchmarks - including 70.6 on RoboCasa Kitchen and 86.7% on LIBERO-Plus - and doubled comparable models on a real-world pouring task (70.8% success). It reaches this dexterous manipulation performance using roughly 20% of the training compute of NVIDIA GR00T N1.5.
One foundation model, every embodiment. RLDX-1 deploys across single-arm, dual-arm, and humanoid robots with high-DoF hands - validated on WIRobotics ALLEX, Franka Research 3, and OpenArm - covering the full lifecycle from data collection to optimized deployment for manufacturing, logistics, retail, and service automation.
AWS Marketplace now accepts line of credit payments through the PNC Vendor Finance program. This program is available to select AWS customers in the US, excluding NV, NC, ND, TN, & VT.
You pay by the hour for running RLDX-1, a foundation model for dexterous robot hands. Pricing splits into two usage modes on the same ml.g5.xlarge instance type. The batch inference option runs the model against grouped workloads processed together. The real-time inference option runs the model for live, interactive control. Both bill per host hour (HostHrs), so your cost scales with how long each instance runs. You choose the mode that fits your workload, and you can run either independently as needed.
Top-of-mind questions for buyers
What compute resource do I get with the ml.g5.xlarge instance for both inference modes?
You run the model on the ml.g5.xlarge instance type, a single GPU-backed machine. Both the batch and real-time modes use this same instance class. Your charge reflects the hours that one instance runs, so each running instance accrues its own host-hour cost.
Am I charged when the inference instance is stopped or idle?
Billing meters each host hour (HostHrs) the instance runs. When you stop an instance, software charges for that instance stop accruing. Underlying AWS infrastructure fees such as storage may still apply separately. Cost scales only with active running time in either mode.
How does the batch inference mode differ from the real-time mode for my bill?
Batch mode runs the model against grouped workloads processed together, suited to non-interactive jobs. Real-time mode runs the model for live, interactive robot control. Both bill per host hour on the ml.g5.xlarge instance. You pick the mode per workload, and each billed independently by running time.

An Amazon SageMaker model package is a pre-trained machine learning model ready to use without additional training. Use the model package to create a model on Amazon SageMaker for real-time inference or batch processing. Amazon SageMaker is a fully managed platform for building, training, and deploying machine learning models at scale.
Deploy the model on Amazon SageMaker AI using the following options:
Real-time inference
Deploy the model as an API endpoint for your applications. When you send data to the endpoint, SageMaker processes it and returns results by API response. The endpoint runs continuously until you delete it. You're billed for software and SageMaker infrastructure costs while the endpoint runs. AWS Marketplace models don't support Amazon SageMaker Asynchronous Inference. For more information, see Deploy models for real-time inference .
Batch transform
Deploy the model to process batches of data stored in Amazon Simple Storage Service (Amazon S3). SageMaker runs the job, processes your data, and returns results to Amazon S3. When complete, SageMaker stops the model. You're billed for software and SageMaker infrastructure costs only during the batch job. Duration depends on your model, instance type, and dataset size. AWS Marketplace models don't support Amazon SageMaker Asynchronous Inference. For more information, see Batch transform for inference with Amazon SageMaker AI .

Summary
RLDX-1 accepts a multimodal observation payload representing a single timestep of a robot's interaction with its environment. Powered by a Multi-Stream Action Transformer (MSAT) architecture, the model processes each modality as an independent input stream and fuses them through joint attention to produce dexterous manipulation actions. Inputs are submitted as a JSON request; image and sensor tensors are provided as [base64-encoded arrays / referenced tensors] in the format below.
Input components
Visual observation - One or more RGB camera frames capturing the scene and the robot's workspace (e.g., a head/front camera and, optionally, wrist-mounted cameras). Format: [H × W × 3] uint8 images at [resolution, e.g., 224×224]. Multiple camera views may be supplied as a list keyed by camera name.
Language instruction - A natural-language task instruction as a UTF-8 text string (e.g., "pick up the cup and pour water into the bowl"). This conditions the model on the intended task and target objects.
Robot state (proprioception) - The robot's current proprioceptive state, including joint positions and, where applicable, end-effector pose and gripper/hand joint angles for high-DoF hands. Format: float array of dimension [robot-specific DoF].
Force / torque signals - Force-torque and/or joint-torque readings that let the model perceive contact and load during contact-rich tasks such as grasping and pouring. Format: float array [sensor-specific dimension]. [Optional depending on embodiment.]
Tactile signals - Tactile sensor readings from the fingertips/hand surfaces, used for fine in-hand manipulation. Format: [sensor-specific array]. [Optional depending on embodiment.]
Embodiment / configuration metadata - Identifier for the target robot embodiment (e.g., single-arm, dual-arm, or humanoid with high-DoF hands) so the model applies the correct action space. [Specify accepted embodiment identifiers.]
The model maintains working memory internally across successive inference calls, so requests should be submitted sequentially in temporal order to preserve context for long-horizon tasks.
