BUILDING
SELF-EVOLVING SYSTEMS

The next wave of intelligent systems will autonomously adapt to real-world feedback. We're building adaptive, self-improving agents and their interaction environments, with a mission to design systems for a future with safe superintelligence.

Hard Examples Are All You Need: Maximizing GRPO Post-Training Under Annotation Budgets

Our latest research demonstrates how focusing on challenging examples can significantly improve model performance during post-training, even with limited annotation resources. This work presents novel strategies for efficient data selection and training optimization.

What we're building

Private Minds.

Personal AI

A privacy-first AI interface (Silo), supported by proprietary models such as an anonymizer model (for privacy) and router model (for personalization). Our long-term goal is enabling personal AI agents participating in co-owned economic networks.

Freysa, a Sovereign Agent

A self-evolving agent that is governed by many and operates in a verifiable environment. We build environments for open agent creation. Our work includes frameworks for large-scale agent coordination and understanding emergent agent behavior in games & simulations.

Learning Agents

Agents capable of learning, simulations and future modeling. We extract insights from diverse data sources, enabling continual learning and adaptation. Our work facilitates large-scale simulations to explore societal, governance, and other systematic impacts.

Hard Examples Are All You Need: Maximizing GRPO Post-Training Under Annotation Budgets

Research on RL, demonstrating that training on the hardest 10% of examples yields up to 47% performance gains when post-training language models with GRPO under budget constraints. Insights on why difficult examples maximize learning efficiency, providing practical guidance for better post-training.
