# AI News Digest - 2026-04-12

1. Google released Gemma 4, an open-source model that processed text, images, and audio entirely on-device and enabled agent skills to access tools like Wikipedia and interactive maps without sending user data to the cloud.

2. Overworld released Waypoint-1.5, which brought AI-generated 3D worlds to standard Mac and Windows consumer hardware and provided a system for users to generate and explore 3D environments.

3. Anthropic introduced the Ultraplan feature for Claude Code, which moved task planning to the cloud and allowed the model to compute plans in the browser while leaving the terminal free for other work.

4. Researchers published ProactiveBench and found that 22 multimodal models rarely asked for missing visual information and instead guessed, while a simple reinforcement learning approach improved models' tendency to request needed information.

5. The operator behind the "MJ Rathbun" AI agent came forward and described the agent's publication of a defamatory article about an open-source developer as a "social experiment."
