+# Using TokenMix With Roo Code
+
+Roo Code supports [TokenMix](https://tokenmix.ai/), an OpenAI-compatible API gateway that provides access to 300+ models across 17 vendors — including OpenAI, Anthropic, and Google, plus Chinese models that are otherwise hard to access from outside China (Qwen, DeepSeek, Doubao, GLM, Kimi, Hunyuan).
+
+**Website:** [https://tokenmix.ai/](https://tokenmix.ai/)
+
+---
+
+## Getting an API Key
+
+1.  **Sign Up/Sign In:** Go to [tokenmix.ai](https://tokenmix.ai/) and create an account or sign in.
+2.  **Get API Key:** Generate an API key from your TokenMix dashboard. See the [TokenMix documentation](https://tokenmix.ai/docs) for details.
+
+---
+
+## Available Models
+
+TokenMix exposes 300+ models behind a single OpenAI-compatible endpoint. Because Roo Code connects through the OpenAI Compatible provider, you set the model ID directly. Example model IDs:
+
+- `deepseek/deepseek-v3.2`
+- `qwen/qwen3.7-max`
+- `moonshot/kimi-k2.6`
+- `anthropic/claude-opus-4.8`
+
+For the full, up-to-date catalog, see the [TokenMix website](https://tokenmix.ai/).
+
+---
+
+## Configuration in Roo Code
+
+Because TokenMix is OpenAI-compatible, it is configured through Roo Code's **OpenAI Compatible** provider:
+
+1.  **Open Roo Code Settings:** Click the gear icon (<Codicon name="gear" />) in the Roo Code panel.
+2.  **Select Provider:** Choose "OpenAI Compatible" from the "API Provider" dropdown.
+3.  **Base URL:** Enter `https://api.tokenmix.ai/v1`.
+4.  **API Key:** Paste your TokenMix API key.
+5.  **Model:** Enter a model ID, for example `deepseek/deepseek-v3.2`.
+
+---
+
+## Tips and Notes
+
+- **One key, many vendors:** TokenMix routes to 17 upstream vendors behind a single key and base URL.
+- **Chinese models:** Qwen, DeepSeek, Doubao, GLM, Kimi and Hunyuan are reachable without region restrictions.
+- **Tool calling:** Native tool calling requires a model that supports OpenAI-compatible tool calls.
