[nixi-agent]: Fixed and merged: #45 (merge commit `62be239`, `main` CI green on all four legs). **What changed** , the endpoints are no longer hard-coded per module. `session.base_url` is now the single source of truth: the text-translation (`/compatible-mode/v1/chat/completions`) and TTS (`/api/v1/services/aigc/multimodal-generation/generation`) endpoints derive their **host** from it, so one `base_url` drives all three legs. (The module constants stay only as function defaults, for callers outside the app.) **Alibaba Cloud Model Studio (international) is now a built-in line**, with the region picker asked for in the comment above: - `session.provider: qianwen | bailian_intl` - host template `wss://{workspace_id}.{region}.maas.aliyuncs.com/api-ws/v1/realtime` - regions: `ap-southeast-1` (Singapore, default) / `ap-northeast-1` (Tokyo) / `us-east-1` (Virginia) / `eu-central-1` (Frankfurt) / `cn-hongkong` - GUI: `Settings → General → Service Line` + Workspace ID (= the API Host prefix from the console, e.g. `llm-xxxx`) + Region. Keys are stored **per line**, so switching lines does not require re-entering the key. - The 401 in the report came from the voice-preview leg (the TTS/multimodal endpoint). That leg now uses the selected line's endpoint as well , which is why the same key previously failed while the realtime leg looked fine. Docs (all five languages) now walk through the
