Google I/O 2025: Gemini 2.5, Ironwood TPU and the ‘AI Matryoshka’
Why in the news
At its 2025 I/O Developer Conference, Google announced an AI-first overhaul of its products. A multi-layered ecosystem called ‘AI Matryoshka’ describes how a core AI model powers every layer, as in nesting dolls.
Key facts
- Gemini 2.5 Pro arrived with a “Deep Think” mode; Gemini 2.5 Flash became the new default.
- Ironwood is the 7th-generation TPU, built for deep learning at hyperscale.
- Developer tools: Gemini API and Vertex AI gained Model Context Protocol (MCP) support, thought summaries and Project Mariner links.
- User products: upgraded Gemini app, AI Mode in Search, agentic commerce features and Gemini-integrated Chrome.
