## Summary

A new benchmark called Realtime‑Bench tests AI on 50 interactive game and web tasks that require real‑time decisions. The test measures three qualities—temporal state awareness, adaptive deliberation, and time‑aware action selection—under three clock settings. GPT‑6 Astra tops the wall‑clock evaluation with a 36 % pass rate, while models reach 70‑80 % under a paused clock.

Google DeepMind announced Genie 4, a world‑model that adds real‑time modification, physics and human action simulation, native sound generation, and complex event simulation. The model is currently a research preview for trusted testers and will later be available to Google AI Ultra subscribers.

Metis, a startup, released a paper proposing an explicit epistemic state to reduce hallucinations, arguing that adding a reasoning core could make AI more reliable.

## Key points

- Realtime‑Bench has 50 tasks, 36 % pass rate for GPT‑6 Astra on wall‑clock
- Genie 4 adds real‑time modification, physics simulation, sound modeling, and complex event simulation
- Metis proposes an explicit epistemic state to lower hallucinations in AI models

## Why it matters

The benchmark shows current models struggle with low‑latency tasks, highlighting limits for real‑time AI applications. Genie 4’s new features push the boundary of interactive world modeling, potentially enabling richer simulation and training environments.
