Gemini 3.5 Flash and Omni launched at Google I/O

Gemini 3.5 Flash is Google's answer to speed + quality — optimized for developers who need fast inference without sacrificing reasoning. Gemini Omni handles video natively, meaning you can feed it actual video files and it understands the content directly. Both are available in preview now. This is the kind of capability shift that changes what's possible in production apps.

Remove AI Watermarks: CLI and library for stripping AI-generated markers

The arms race is real: this open-source tool removes AI watermarks from images. It's a sobering reminder that watermarking alone doesn't solve the authenticity problem. The cat-and-mouse game between detection and evasion is just getting started.
