Android Authority·medium signal

Ahead of Google I/O on May 19, leaks and previews point to Gemini 4 as the flagship announcement — a model with a 2M token context window large enough to fit entire codebases without RAG. An upgraded agent called 'Remy' will offer proactive 24/7 assistance, marking Google's shift from responsive to proactive AI. The move from chatbot to autonomous multi-step workflow execution is the key strategic pivot.
