LM Studio 0.4 introduces a fully headless mode via the `lms` CLI, enabling local LLM API servers without a desktop GUI. The tutorial covers installing the CLI, downloading and managing GGUF models with quantization options, launching an OpenAI-compatible HTTP API server from the command line, building a Node.js client using the OpenAI SDK with streaming and retry logic, wiring up a React chat frontend with real-time token streaming via a backend proxy, and automating deployment with a shell script and systemd service. Security considerations for network binding and production hardening are also addressed throughout.
