llm-openrouter library 0.6 adds multi-model support and streaming — developers can now switch between AI providers without rewriting code

Simon Willison released version 0.6 of llm-openrouter, a Python tool that lets developers access multiple AI language models (like Claude, GPT-4, Llama) through a single interface. The update adds the ability to stream responses in real-time, so outputs appear word-by-word instead of waiting for the entire answer.
