+`run_bench.py` uses the global OpenAI-compatible endpoint by default. Set
+`MINIMAX_API_BASE=https://api.minimaxi.com/v1` to use the China endpoint.
+
+The official API entry points are:
+
+| Region | OpenAI-compatible Base URL | Anthropic-compatible Base URL |
+| --- | --- | --- |
+| Global | `https://api.minimax.io/v1` | `https://api.minimax.io/anthropic` |
+| China | `https://api.minimaxi.com/v1` | `https://api.minimaxi.com/anthropic` |
+
+For Anthropic SDK integrations, pass the `/anthropic` Base URL unchanged. The SDK
+appends `/v1/messages` when creating a message.
