Google Debuts Gemini 3.5 Flash and Gemini Spark Agent — Renames Vertex AI to Gemini Enterprise Agent Platform

CNBC / Google·medium signal

Google launched Gemini 3.5 Flash at half to one-third the cost of comparable frontier models, plus Gemini Spark, a general-purpose AI agent that reasons across connected apps (beta for Ultra subscribers). Google completed the full rebrand of Vertex AI to Gemini Enterprise Agent Platform, absorbing Agentspace and adding Workspace Studio (no-code agent builder) and Project Mariner (web-browsing agent). Vertex AI no longer exists in the Cloud Console — all searches redirect to Agent Platform.
