We have made important strides towards solving two manual bottlenecks to continual learning: reward, and envrionments.

Continual grading: Rather than needing to manually label thousands of traces, we present a metagrader - a model that can learn off of a subset of representative reward.

Group Size 1 (GS1): Instead of methods like GRPO that require groups and therefore offline environments, we explore methods were you only rollout once, proposing a stabilized algorithm GS1, where the environment becomes the product itself.

We test both of these methods on frontier, economically valuable benchmarks like PRBench, Harvey LAB, and AutomationBench and achieve frontier results.

Today we are launching the Trajectory platform, the easiest and most intuitive tool to post-train models of your own.

The first step to continual learning is empowering every individual to train, eval, and deploy models with just a few agent prompts.

The second is the frontier research that breaks down barriers to reward functions and environments.
Here, we present Group Size 1 (GS1) and Continual Graders in beta.

We believe in a world where AI gets smarter the more it's used, and Trajectory is the way to get there.

Imagine if everyone had the tools to shape intelligence itself. That day is today.

Today we launch the Trajectory platform - the easiest and most intuitive tool to post-train models of your own. The foundation for continual learning.

With just a few agent prompts, you get access to a full creative suite to train, eval, and deploy trillion parameter models.

On top of that, we believe in a future where you don’t just shape your model once, it also keeps learning on its own from the world around it.

We’re releasing two research previews.

1. Continual grading scales your taste, so your model learns what good looks like from far more than you could ever grade by hand.
2. GS1, a new algorithm that lets models learn directly from what they do in production.

We’ve now raised 60M, with a new round led by @Sequoia at a 300M valuation to democratize the most powerful technology of today - training models - so that the lawyers, doctors, and engineers of the world can own their own intelligence.

You know what good looks like, now go build it. Own your own value function with Trajectory.
