LLM-Models – a CLI Tool to List Available LLM Models Across Providers

I built a simple CLI tool to solve a problem I kept running into: which exact model names are actually available through OpenAI, Anthropic, Google, and xAI APIs at any given time?

The APIs themselves provide this info, but I got tired of checking docs or writing one-off scripts. Now I can just run:

$ llm-models -p Anthropic

and get the current list with human-readable names.

Installation:

  macOS: brew tap ljbuturovic/tap && brew install llm-models
  Linux: pipx install llm-models
  Windows: pip install llm-models

Built with help from Claude Code. The tool queries each provider's API directly, so you get real-time availability rather than stale documentation.

Open to feedback and happy to add more providers if there's interest!
