+summary: "Use Xiaomi MiMo (mimo-v2-flash) with Moltbot"
+read_when:
+  - You want Xiaomi MiMo models in Moltbot
+  - You need XIAOMI_API_KEY setup
+---
+# Xiaomi MiMo
+
+Xiaomi MiMo is the API platform for **MiMo** models. It provides REST APIs compatible with
+OpenAI and Anthropic formats and uses API keys for authentication. Create your API key in
+the [Xiaomi MiMo console](https://platform.xiaomimimo.com/#/console/api-keys). Moltbot uses
+the `xiaomi` provider with a Xiaomi MiMo API key.
+
+## Model overview
+
+- **mimo-v2-flash**: 262144-token context window, Anthropic Messages API compatible.
+- Base URL: `https://api.xiaomimimo.com/anthropic`
+- Authorization: `Bearer $XIAOMI_API_KEY`
+
+## CLI setup
+
+```bash
+moltbot onboard --auth-choice xiaomi-api-key
+# or non-interactive
+moltbot onboard --auth-choice xiaomi-api-key --xiaomi-api-key "$XIAOMI_API_KEY"
+```
+
+## Config snippet
+
+```json5
+{
+  env: { XIAOMI_API_KEY: "your-key" },
+  agents: { defaults: { model: { primary: "xiaomi/mimo-v2-flash" } } },
+  models: {
+    mode: "merge",
+    providers: {
+      xiaomi: {
+        baseUrl: "https://api.xiaomimimo.com/anthropic",
+        api: "anthropic-messages",
+        apiKey: "XIAOMI_API_KEY",
+        models: [
+          {
+            id: "mimo-v2-flash",
+            name: "Xiaomi MiMo V2 Flash",
+            reasoning: false,
+            input: ["text"],
+            cost: { input: 0, output: 0, cacheRead: 0, cacheWrite: 0 },
+            contextWindow: 262144,
+            maxTokens: 8192
+          }
+        ]
+      }
+    }
+  }
+}
+```
+
+## Notes
+
+- Model ref: `xiaomi/mimo-v2-flash`.
+- The provider is injected automatically when `XIAOMI_API_KEY` is set (or an auth profile exists).
+- See [/concepts/model-providers](/concepts/model-providers) for provider rules.
