pub const QWEN_BASE_URL_ENV: &str = "QWEN_BASE_URL";Expand description
Read when neither BASE_URL_ENV nor a key for the default endpoint is
set: Qwen Cloud’s OpenAI-compatible mode, for a contributor who has that
subscription rather than a Gemini key. The base URL is the one DashScope
documents for compatible mode, ending in /compatible-mode/v1.
