Google unveiled Antigravity 2.0 at Google I/O 2026 with an updated desktop app, a command-line interface (CLI) tool, and a software development kit (SDK) for custom workflows [1, 2]. The desktop app lets users orchestrate multiple agents simultaneously, run tasks in parallel, and schedule background activities [1, 2].
Antigravity 2.0 is powered by Google’s Gemini 3.5 Flash model, optimized for agent tasks and coding workflows with high efficiency for complex, long-running jobs [1, 2, 3, 4, 5]. The Gemini 3.5 Flash model is the outcome of co-development efforts using the Antigravity platform [1, 2, 3, 4, 5].
Google added native voice commands support and replaced its previous Gemini CLI tool with the new Antigravity CLI tool [1, 2].
Alongside Antigravity 2.0, Google launched a new AI Ultra subscription tier priced at $100 per month in the US [1, 2, 6, 7, 3, 4, 5]. This new middle tier offers 5 times higher usage limits than the Pro plan, 20 terabytes of cloud storage, and a YouTube Premium subscription [6, 3, 4, 5]. The former AI Ultra top tier plan was reduced from $250 to $200 per month, providing 20 times the Pro usage limits and access to the experimental Project Genie prototype, a world-building tool integrating Street View data [1, 2, 6, 7, 3, 4, 5].
Google replaced daily prompt limits with a new compute-based metering system that calculates usage by prompt complexity, model type, features, and chat length. Usage quotas now reset every five hours [6, 3, 4]. This change caused backlash from free and paid Gemini users upset about quota shortages and throttling [8, 9, 10]. Despite this, Google has increased weekly Gemini model usage limits for Antigravity paid users in two steps, tripling them each time for a net 9x increase over original quotas [10, 11]. Varun Mohan, Google DeepMind Antigravity lead, said, "We’re 3xing the rate limits for Gemini models across all paid tiers in Antigravity and resetting everyone’s Gemini quota for the week." He added, "Yesterday, we 3x’d limits on Antigravity and are seeing you build so much more. One thing we heard was people are worried about hitting their weekly limits after a couple work sessions. To give you more runway, we’re 3x’ing the weekly Gemini quotas AGAIN on all paid plans." [11]
The $100 and $200 AI Ultra plans include access to Gemini Spark, a 24/7 AI agent that integrates with Gmail, Calendar, Docs, and other Google products to assist workflows in the US [4, 5]. The top-tier $200 plan includes Project Genie, available globally to subscribers aged 18 and older [4, 5].
Google also introduced Gemini Omni, a new flagship multimodal model capable of generating content from text, images, and video inputs, designed for consistent output across contexts [4, 5].
Google’s subscriptions bundle productivity AI tools such as Gmail AI Inbox and daily briefings at different tiers [4, 5].
The company’s next update will continue expanding Antigravity’s Gemini usage quotas and further tune the compute-based metering system. [11]
