## Summary

Trajectory Labs has launched a developer platform for post-training models, according to Santiago's repost of the company's announcement. Users supply tasks, data, and evaluation criteria, and the platform handles post-training, evaluation, and deployment. The company also released two research previews, Continual grading and GS1, and said it raised $60M in a round led by Sequoia at a $300M valuation.

## Why it matters

The post combines a fine-tuning platform launch with a $60M round at a $300M valuation, showing how a training tool is being positioned for non-specialists.

## Post

This is a new developer platform for fine-tuning models.

You provide:

• The tasks the model should solve
• The data the model needs to solve them
• The criteria to evaluate the results

@trajectorylabs will take this and handle post-training, evaluation, and deployment.

> 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.
