Praxis-1 YAM - Reactor

Praxis-1 YAM predicts a chunk of end-effector pose targets and gripper targets for two arms. Its inputs are a top camera, two wrist cameras, the measured pose and gripper of each arm, and a task instruction. Reactor runs inference, and your application executes the returned targets.

Model information

Property	Value
Model identifier	`reactor/praxis-1-yam`
Family	Praxis-1
Reference embodiment	Bimanual YAM: two YAM arms with grippers
Inputs	Three RGB camera tracks, both arms’ measured end-effector poses and grippers, and a task instruction
Outputs	Absolute end-effector pose and gripper targets for each arm, one row per control step at 15 Hz. A chunk has 24 rows (1.6 seconds of motion).
Session price	$0.030/min, metered per second. See Pricing & Billing.

The model identifier, reactor/praxis-1-yam, selects the YAM variant. Other Praxis-1 checkpoints and robot embodiments do not inherit this observation and action contract. Matching the number of input and output values does not establish compatibility: camera placement, pose frame, gripper convention, and training distribution must match.
