Google upgrades NotebookLM with Gemini 3.5 and Antigravity, cuts AI Plus price, then hits June 10 outage

Google pushed a set of Gemini updates this week, led by a NotebookLM upgrade to the latest Gemini 3.5 model plus the new Antigravity capability, which adds a cloud computer and source-finding tools to the research assistant. Separately, Google cut the price of its AI Plus consumer plan while doubling included cloud storage — a direct pricing shot at OpenAI and Anthropic subscription tiers.

The momentum was undercut by a major Gemini outage on June 10 that sent users hunting for workarounds, a reminder that reliability remains a competitive axis as more workflows depend on always-on assistants. Google also continued its multimodal push, with Logan Kilpatrick introducing Gemini 3.5 Flash Live Translate, a real-time speech-to-speech translation model amplified by Demis Hassabis and Sundar Pichai.

The pricing cut is the strategic story: as routing startups and cheaper Chinese models commoditize raw capability, Google is leaning on distribution and bundled storage to lock in consumers. The risk is margin compression at exactly the moment compute costs are spiking. For developers, Antigravity and the cloud-computer features signal Google's intent to make NotebookLM an agentic workspace rather than a passive summarizer — but the outage shows the operational bar that ambition demands.
