lmti 1.5.0

Language Model Terminal Interface.

Language Model Terminal Interface

Often I just want to talk to LMs without the agentic clutter: I dont want it to read my stuff, access my files or consume through a gazillion tokens of tools, skills, MCPs and what not. I just want a recipe for gazpacho, c'mon :(

For that, I normally have to log into a WebApp from a provider (i.e. Mistral LeChat, Gemini, ChatGPT). But I live on the terminal, so I made a thin wrapper.

If somehow you landed here but you are looking for an actual agent that can manage your system, I'd recommend you look into pi, opencode or mistral-vibe (in that order). If your desire is to become vendor locked and further push private companies in their quest for the oligopoly, you could check Claude Code or Codex, I guess :)

FAQ

• Can I talk with LMs from different providers from the terminal? - Yes :)
• Does the app have access to my files? - No
• Can the app run terminal commands? - Nope
• Can the app execute code? - Nein
• Does the app have any sort of agentic loop? - Negative
• Can I connect the app to MCPs or other tools? - Also no
