Concepts
Understand what environments are, how they power evaluation, agent optimization, and training, and how the same components serve all three.
Concept Highlights
Each explainer below covers one foundational idea and links to deeper material.
Environments

Evaluation
How environments are used to measure model and agent performance.
Training
Post-training techniques and how environments are used for training.
Key Terminology
