so anyone already made something like antigravity that can be used with any models or open source models..??? Yes, absolutely. You do not need to wait for Google or Anthropic. The developer community has built incredibly powerful, 100% open-source, model-agnostic coding agents that do the exact same thing as Google Antigravity and Claude Code . These open-source tools allow you to bring your own API keys (Gemini, OpenAI, Anthropic, DeepSeek) or run completely free local open-source models (like Llama 3 or DeepSeek-Coder via Ollama).
