Using Gemini 3, Mollick had the model build an interactive simulator based on his past posts. The model completed the entire process, from writing the code to designing the interface, moving beyond simple text generation.
Alongside the model, Google also released Antigravity, an autonomous tool. Similar to Claude Code or OpenAI Codex, it is a programming-specialized tool with access to the computer.
Antigravity functions as an agent that autonomously executes tasks instructed by the user. It performs work via code based on English instructions and features a concept called the "Inbox," where it requests user permission as needed.
This tool is said to enable tasks such as building dashboards, operating websites, and reading files. Mollick stated that agents with coding capabilities are evolving into general-purpose tools [One Useful Thing].
