OpenMatter describes a service that simulates robot tasks, fine-tunes a model on the resulting trajectories, and returns weights, a dataset, and an evaluation report.

Landing page captured for the 2026-09-24 issue.

For: Robotics teams training physical AI models
Worth noticing: The workflow varies 4,096 simulation passes and lists delivered weights, a dataset, and an evaluation report.

Field notes

The page frames the process as rehearsal before hardware deployment: simulate the robot's job, collect labelled trajectories, and compare checkpoints using evaluation numbers. It displays example output sizes—812 GB simulated, 48.3 GB dataset, 2.1 GB weights, and a 1.8 MB evaluation report—without identifying them as results from a completed customer run. OpenMatter says it deletes its copy when a run closes.
