Builder and research activity is accelerating faster than evaluation evidence.

Without a failure metric, an AI system is only a story. The topic is rising; public suites are still scarce.

VLM, VLA, simulation and world models. Uneven maturity, still-unstable vocabulary.

Vision-language-action demos are multiplying faster than reproducible stacks.

Coding assistants are a daily tool. The Lab uses them; it has not published one.
