Daily Briefing: Google's I/O Stack — Flash 3.5, Omni, and the Ecosystem Play

Google used I/O 2026 to ship an interlocking platform stack rather than a single flagship model. Gemini 3.5 Flash delivers four-times-faster inference at roughly half the cost; Gemini Omni introduces iterative multimodal video editing; SynthID brings AI content detection directly into Search and Gemini; and the Antigravity developer platform tripled its rate limits permanently. The common thread is a deliberate bet that deployment economics and ecosystem integration matter more than benchmark leadership — and that switching costs rise with every layer a customer adopts. Meanwhile, DeepSeek made its 75% V4 Pro discount permanent, reinforcing the broader signal that the model layer is commoditizing fast.
