Trajectory announces AI post-training platform and opens waitlist

In the announcement, @rronak_ said users could train, evaluate and deploy trillion-parameter models with a few agent prompts. That is Trajectory’s description of what the platform can do, not a tested result.

Trajectory also described two research previews. It said continual grading could scale a user’s judgments beyond what they could grade by hand. It described GS1 as an algorithm that lets models learn from what they do in production. Both are presented as previews, not established results.

The same post said Trajectory had raised 60M, including a new round led by Sequoia at a 300M valuation. The post did not specify a currency or the size of the new round.
