Google's Gemini Spark, its always-on AI agent powered by Gemini Flash models and Antigravity infrastructure, launched in beta at I/O 2026 exclusively for paid subscribers. It remains unavailable on the free Gemini tier despite expansions to the $19.99 AI Pro plan and deeper Workspace integrations like Gmail, Docs, Photos, and third-party apps such as Canva and Instacart. Trader sentiment reflects Google's strategy of tiered monetization amid competition from agentic tools like Claude and OpenClaw, with no official signals of a free rollout. Key upcoming catalysts include further macOS enhancements, real-time topic tracking, and potential pricing or eligibility updates that could shift access dynamics before year-end.
