Use nous-genai as an end user (not a contributor): run `genai` CLI for text/image/audio/video/embedding across providers (OpenAI/Gemini/Claude/DashScope/Doubao/Tuzi), save binary outputs, list available models, and start a local MCP server (Streamable HTTP/SSE) with auth. Use when setting up `.env.local` provider keys, choosing `{provider}:{model_id}`, or debugging common issues (auth/timeout/SSRF-download/MCP bearer-token rules). 中文: 用 nous-genai 调用多家大模型 + 启动 MCP 服务 + 排错。
