Antigravity CLI
google-antigravity/antigravity-cli
Google Antigravity's reasoning and execution, in the terminal.
The Antigravity CLI brings the reasoning, execution and orchestration capabilities of Google's Antigravity platform to the command line — headless access to the same harness the IDE exposes, with a companion Python SDK (antigravity-sdk-python).

Google launches Gemini 3 and the Antigravity agentic IDE
Gemini 3 debuts with state-of-the-art agentic coding benchmarks, alongside Antigravity — a browser-based agentic development environment where agents plan, edit and execute tasks across editor and browser surfaces.
OpenAI open-sources Symphony, its codex orchestration harness
OpenAI releases Symphony — open-source orchestration that turns project work into isolated, autonomous coding-agent implementation runs and surfaces the ones that pass, so teams manage outcomes instead of supervising sessions. Big Tech keeps raising the floor on what counts as a baseline harness.
Google's Agent2Agent protocol moves to the Linux Foundation
The A2A protocol — backed by 50+ partners at launch — is donated to the Linux Foundation for neutral, open governance, standardizing how agents discover and talk to each other.
Google open-sources the Agent Development Kit
Google launches ADK, a modular open-source framework for building agents with Gemini integration, multi-agent hierarchies and A2A support — Google's major entry into the framework wars.
