Models that never stoplearning

Every model out there knows the whole internet and nothing about the enterprise it works for. It stops learning the day it ships.

Ours never stop

No knowledge cutoff. Every interaction and what happened next goes back into the weights.

Sarathi models trained from scratch

Schnitt trains Sarathi from scratch, then keeps training it on every interaction it has. Interactions and their outcomes become training data for continued pretraining and RL environments, and the model is retrained. Not a bigger prompt. New weights.

The bet

Self-improving models are the next frontier We are betting big on RSI

A model that learns from every interaction it has, then learns to improve how it learns. That is where the frontier is going. Sarathi gets there in three steps.

STEP 01
Continual learning

Continued pretraining on every interaction and its outcome. No knowledge cutoff. The model on Friday is not the model it was on Monday.

STEP 02
RL environments

Reinforcement learning in environments built from real outcomes, so the model is rewarded for what actually happened, not for what a rater liked.

STEP 03
Recursive self-improvement

A model that improves its own training. The frontier is racing toward it. So are we.
