At Google’s annual I/O developer conference in Mountain View, California, Alphabet announced AI agents integrated into Search that autonomously complete tasks like making purchases and monitoring ticket availabilities. The company launched Gemini 3.5 Flash, a model for coding and automated tasks, with 3.5 Pro coming next month. Alphabet lowered its top-tier AI Ultra subscription plan to $200 a month from $250 and announced a $100-a-month version for developers. CEO Sundar Pichai said heavy users could save more than $1 billion a year by switching to Google’s models, which he stated could offer similar performance to other frontier models at up to one-third of the cost. Google also released a new version of coding assistant Antigravity, competing with Anthropic’s Claude Code.
