Connecting an AI model

MoilStack .md works with OpenAI-compatible APIs (Groq, Gemini, OpenAI, Mistral, Together AI), Anthropic's API, Ollama running locally or in the cloud, and installed CLI tools like Claude Code. A few starter models are added on first launch — just add an API key or log in to the CLI. Use Ollama to keep everything fully offline.
