Tencent Cloud serves the Hunyuan models internationally through TokenHub, an OpenAI-compatible API: https://tokenhub-intl.tencentcloudmaas.com/v1 (Singapore) or https://tokenhub-us.tencentcloudmaas.com/v1 (Silicon Valley).
Create a TokenHub API key in the Tencent Cloud console and send it as Authorization: Bearer <key>. In the examples it's written {{TENCENT_TOKENHUB_KEY}}. Check which models your region offers with the models call.
