Antigravity elevated agents to a first-class surface: they plan, execute, and verify tasks while developers steer mid-flight. Built on GeminiGoogle's family of multimodal AI models — successors to PaLM and competitors to GPT and Claude. 3 Pro with support for Claude Sonnet 4.5 and open models, it competed directly with Cursor, CopilotAn AI coding assistant — suggests completions and edits inside the editor as you type., and Claude Code for the agenticAI systems that plan and execute multi-step tasks autonomously — tools, browsing, and sub-agents.
