Langcli is an interactive AI coding assistant in the terminal. Its core features include: (1) the way to use Langcli is exactly the same as that of standard Claude Code; (2) allowing you to friendly use and switch between mainstream LLM models (including claude opus 4.6, claude sonnet 4.6, kimi k2.5, minimax M2.5, deepseek v3.2, etc.) within an ongoing session as needed, without interrupting your context.
