Vercel CEO Guillermo Rauch announced open-source, bring-your-own-model templates for both v0 and Vercel Agent, powered by the AI SDK, Vercel AI Gateway, and Sandbox. The template supports Claude Code, OpenAI Codex CLI, GitHub Copilot CLI, Cursor CLI, Gemini CLI, and opencode — meaning developers can build their own v0-equivalent coding agent with any model provider. This democratizes the coding agent architecture that powers v0's 3 million users, turning Vercel's proprietary agent pipeline into an open-source commodity.
