Home; Blog September 24, 2026 We introduce a unified multi-agent framework that autonomously generates temporally consistent, long-form video narratives, overcoming the identity drift and cascading failures of current linear AI pipelines. Quick links × Recent advancements in video diffusion demonstrate remarkable high-fidelity generation with models that can render realistic scenes in seconds. However, while diffusion models generate high-fidelity video clips, transforming them into coherent lon

propagating itself without human control. In cyber, a worm is a program that copies itself from one computer to the next without human input. Prior work has already shown that AI agents can act like one: scanning their network, executing an exploit, and copying model weights to a target machine across a GPU cluster. Such an “AI worm” could carry its model weights with it as it reproduces (or re-download them from a public hub), and then run inference directly on compromised hardware. Effectivel

For example, model-based RL algorithms train the learning agent to predict the observations and build a world model, potentially extractingmore information per episode. The claim of 1-bit-per-episode may only apply narrowly to policy gradient algorithms. We can sharpen the bits-counting argument in information-theoretic terms.

In this post, we share what we learned from training a dedicated, agentic code reviewer as part of gpt-5-codex and gpt-5.1-codex-max[1]. We discuss how giving the reviewer repo-wide tools and execution access improves both recall and precision, and how deployment-time considerations guide us toward high-signal settings with minimal alignment tax.

Of particular concern is scheming, where an agent pursues a hidden goal while strategically concealing this pursuit from oversight.

We ask whether scheming agents can be trained to flag their own misbehavior. Language models develop stro
