Trajectory launches post-training platform to train and continually learn trillion-parameter models

simonguozirui · x · 2026-11-03

Trajectory launched its post-training platform, billed as the easiest tool to post-train your own models and a foundation for continual learning. With a few agent prompts you get a creative suite to train, eval and deploy trillion-parameter models. Two research previews ship: Continual grading, which scales your taste so the model learns what "good" looks like beyond what you could grade by hand, and GS1, a new algorithm. cHHillee (Thinking Machines) notes Trajectory was an early Tinker customer whose experimental post-training work informed Tinker's roadmap.
