Solstice OpenEnv provides two novel Gymnasium-compatible environments for evaluating agentic AI: 1. MeridianEnv - Tests agents on energy grid battery dispatch optimization, requiring physics-aware decision-making under dynamic pricing and demand conditions. 2. BlackSwanEnv - Evaluates agents' ability to identify overlooked high-impact risks through eight contrarian analytical perspectives, testing reasoning beyond conventional patterns. Both environments feature automated scoring, reproducible execution via Docker, and realistic tasks that challenge genuine agentic capabilities.
