GAIA is an OpenEnv-compatible geospatial reasoning environment where an AI agent infers hidden real-world locations using multi-step tool calls (terrain, weather, sun angle, language, architecture, street/aerial cues) under strict action budgets. It includes an oversight agent that flags contradictions and overconfidence, plus a GRPO training pipeline (TRL + OpenEnv) to improve policy rewards over time, with a live Cesium interface for real-time demo and evaluation.
