Google is widening access to Gemini Spark, its agentic artificial-intelligence platform, making it available to Google AI Pro subscribers across the United States starting this week and to Google AI Ultra subscribers worldwide with local-language support.

The expansion, announced Wednesday, marks a significant step in Google's effort to convert its chatbot user base into a platform for autonomous software agents capable of planning trips, drafting emails, and interacting with third-party services on a user's behalf. Previously, Spark was limited to Ultra-tier subscribers in the United States after its debut at Google I/O earlier this year.

The move comes as Alphabet reported that Gemini now reaches 950 million monthly active users, up from 750 million in February. Parent company Alphabet also disclosed second-quarter revenue of $119.8 billion, a 24 percent increase year over year, though some investors expressed concern that returns on massive AI capital expenditures remain uncertain.

Gemini Spark is designed to function as an autonomous assistant that can browse the web, manage calendars, and execute multi-step tasks without constant user prompting. Google framed the wider rollout as a response to strong demand from Pro-tier users who had requested agentic capabilities after seeing demonstrations at I/O.

The announcement places Google more directly in competition with OpenAI, which recently brought its GPT-Live voice mode to desktop applications, and Anthropic, which has been expanding the enterprise features of its Claude Code agent. All three companies are racing to convince businesses and consumers that AI agents can move beyond simple chat responses to perform meaningful work.
