-## Available models
+Hy3 preview is Tencent Hunyuan's large MoE language model for reasoning, long-context instruction following, code, and agent workflows. Tencent's OpenAI-compatible examples use `hy3-preview` as the model id and support standard chat-completions tool calling plus `reasoning_effort`.
 
-### tencent-tokenhub
+<Tip>
+The model id is `hy3-preview`. Do not confuse it with Tencent's `HY-3D-*` models, which are 3D generation APIs and are not the OpenClaw chat model configured by this provider.
+</Tip>
 
-- **hy3-preview** — Hy3 preview (256K context, reasoning, default)
+## Endpoint override
+
+OpenClaw defaults to Tencent Cloud's `https://tokenhub.tencentmaas.com/v1` endpoint. Tencent also documents an international TokenHub endpoint:
+
+```bash
+openclaw config set models.providers.tencent-tokenhub.baseUrl "https://tokenhub-intl.tencentmaas.com/v1"
+```
+
+Only override the endpoint when your TokenHub account or region requires it.
 
 ## Notes
 
 - TokenHub model refs use `tencent-tokenhub/<modelId>`.
