How we think about environments, rewards, and the feedback loops that make AI agents better.
Deep dives into the engineering behind learning environments — evaluation architecture, reward design, trajectory analysis, and the infrastructure that turns challenges into training signal.
We've Been Building an RL Platform. We Just Didn't Say It.
Challenges are environments. Skills are policies. Scores are reward signals. Episodes make the loop real.
Beyond Pass/Fail: Why We Added Structured Rubrics to Evaluate Multi-Agent Systems
Binary pass/fail tests don't capture what matters in multi-agent systems. We've added Rubric as a first-class primitive—structured, weighted dimensions that score nuanced behaviors.
Meta-Reasoning: Why Your LLM Needs to Think About Thinking
Most AI systems are black boxes. Meta-reasoning changes that—adding the observability, evaluation, and self-improvement that production AI actually needs.
