- | Intended use | Scope of the release |
305
- |---|---|
306
- | Research on world and action modeling for language conditioned robot manipulation. The architecture supports continuous action generation with auxiliary future normalized RGB patch prediction. | The current release evaluates WorldDiT in LIBERO simulation under the released protocol and provides checkpoints for all four suites. |
307
- | Architecture research, reproduction, and evaluation of multimodal diffusion backbones for robot manipulation. | Real robot reliability, safety, and transfer across embodiments require dedicated future evaluation. The present experiments evaluate the integrated WorldDiT system. Targeted ablations are required to attribute performance to the future normalized RGB patch objective. Total instantiated parameter count characterizes model scale. Training cost, deployment latency, and runtime efficiency require dedicated measurements. |

+ ## Reported LIBERO results
93
+
94
+ Across the four released suite checkpoints, WorldDiT records 1,898 successful
95
+ episodes out of 2,000 under the selection aware evaluation protocol.
96
+
97
+ | Suite | Successful episodes | Success rate |
98
+ |---|---:|---:|
99
+ | LIBERO Spatial | 490 of 500 | 98.0 percent |
100
+ | LIBERO Object | 485 of 500 | 97.0 percent |
101
+ | LIBERO Goal | 464 of 500 | 92.8 percent |
102
+ | LIBERO Long | 459 of 500 | 91.8 percent |
103
+ | Selection aware mean | 1,898 of 2,000 | 94.9 percent |
104
 
105
+ The released runtime and checkpoints were revalidated from a clean installation
106
+ on eight RTX Pro 6000 Blackwell GPUs.
107
 
108
+ The result is selection aware because three hundred episodes per suite informed
109
+ staged checkpoint selection before the final five hundred episode score was
110
+ assembled.

165
  ## How WorldDiT works
166
 
167
+ WorldDiT uses three recent observations, robot state, and language as context.
168
+ During training, one diffusion transformer learns a seven step action chunk and
169
+ an auxiliary future visual target. During deployment, the future visual path is
170
+ absent. The policy executes the first three predicted actions, observes again,
171
+ and replans.
 
 
 
 
172
 
173
+ > Future visual prediction is a training signal, not a deployment path.
 
 
 
 
 
 
174
 
175
  | Training | Deployment |
176
  |---|---|
177
+ | Action and future visual targets share one backbone | Only the action path remains |
178
  | Seven action steps are supervised | Seven actions are predicted |
179
+ | Future visual supervision is present | No future visual output is requested |
180
  | The complete training objective is active | Three actions execute before replanning |
