Bytedance planned to launch its AI video model Seedance 2.0 globally in mid-March. That's not happening, because Hollywood's biggest studios have collectively put the brakes on the rollout. The backlash is also a sign of just how convincing AI-generated video has become.

While most reinforcement learning algorithms use two to five network layers, a research team achieved 2x to 50x performance gains by scaling network depth up to 1,024 layers in a self-supervised agent and saw entirely new behaviors emerge in the process.

AI agents usually throw away valuable feedback from everyday interactions. Princeton's new OpenClaw-RL framework changes that by turning live signals from chats, terminal commands, and GUI actions into continuous training data. The researchers say just a few dozen interactions are enough for noticeable improvements.

AI agents can hack systems, defend them, and be hacked themselves. Codewall's one-hour takeover of an AI recruiting platform shows just how tangled this new security landscape has become.

The job calls for someone who can “recognize, express, and shift between emotions in a way that feels authentic and human.”
