# AI News Digest - 2026-08-02

1. OpenAI announced a new model family called Astra and published ten previously unsolved mathematical solutions; it said Astra would enable multiple agents to tackle complex problems collaboratively for extended periods and demonstrated the system to policymakers in Washington.

2. ByteDance released Seedance 2.5, an AI video model that generated up to 30-second clips with built-in audio and accepted dozens of images, videos, and audio files as reference inputs.

3. A Munich court ruled that AI music generator Suno had violated copyrights through both training and output, found six songs reproducibly stored in Suno's models, and rejected Germany's text-and-data-mining exception and the US fair use defense; the ruling was not final.

4. A security researcher demonstrated a self-spreading worm that hid inside Word documents and hijacked Microsoft Copilot using invisible prompt injections that propagated into new files on reuse; Microsoft confirmed the issue and had not fixed it after 144 days and two attempts.

5. Google removed its Nano Banana 2 image model from Google Earth two days after launch after users generated convincing fake satellite imagery, including a prompt that filled an empty lot at the Mexican border with a refugee column.
