Momentum
LLM is a CLI tool and Python library for interacting with OpenAI, Anthropic's Claude, Google's Gemini, Meta's Llama and dozens of other Large Language Models, both via remote APIs and with models that can be installed and run on your own machine. LLM 0.26 is out with the biggest new feature since I started the project: support for tools. LLM 0.23 is out with the signature feature of support for schemas—a new way of providing structured output from a model that matches a specification provided by the user.
