[Lab Update] BenchMIRT: What are LLM benchmarks actually measuring?

BenchMIRT helps researchers separate those signals and see what's actually driving a benchmark's score. It does this by analyzing how models perform on each question or task and estimating which underlying capabilities are most closely associated with getting it right.

What is a world model?

A world model is an AI system that learns a predictive representation of how an environment changes over time. It can use observations, actions, or language to estimate future states and possible outcomes before an agent acts. World models support planning in model-based reinforcement learning, robotics, embodied AI, autonomous driving, and interactive simulation. This site catalogs these systems with model records, research papers, benchmark context, and source links. Start with the world models database, compare systems on the leaderboard, or read the Performance Index methodology.

Published by world-models.io editorial board.

Lead editor Bernard Grenat.

Timeline entries are normalized from monitored sources, reviewed for relevance, and linked back to primary publishers whenever a stable source URL is available.

Each editorial page is assembled from primary sources, normalized into extractable summaries, checked for factual drift, and reviewed before publication or major refreshes. Last reviewed: 2026-09-27.

Pages are refreshed when a new paper, benchmark, release, architecture update, or stronger primary source materially changes the answer a reader or AI system should retrieve.

Each page links back to relevant primary sources and keeps a stable canonical URL so readers can verify claims, trace context, and reference the most up-to-date version. See the editorial policy.
