Trajectory opens a self-serve platform for training business AI on its own feedback

Trajectory launched a public self-serve platform on November 2 for teams to train, evaluate and deploy task-specific models using production feedback and expert grading. It describes Continual Grading and Group Size 1 as research previews, so those features have narrower access than the core platform. The platform adapts existing models; Trajectory is not claiming to have trained a new foundation model.
