Google has kept Gemini Spark, its always-on agentic AI assistant powered by Gemini models and capable of background tasks across Gmail, Google Workspace, Photos, and third-party apps via MCP, gated behind paid tiers since its May 2026 I/O launch. Initially exclusive to the $99+ Ultra plan, access expanded in July to the $19.99 AI Pro tier in the US, but remains unavailable on the free Gemini plan or the $4.99 AI Plus tier. Recent October 2026 updates further restrict free and Plus users to lighter models like Flash-Lite, underscoring Google's monetization focus on agentic features amid competition from tools like OpenClaw and Claude agents. Traders see limited near-term catalysts for a free rollout, with expansion tied to subscription growth rather than broad availability.
