+summary: "Use NanoGPT's OpenAI-compatible API in Clawdbot"
+read_when:
+  - You want to use NanoGPT as a model provider
+  - You need a NanoGPT API key or base URL setup
+---
+# NanoGPT
+
+NanoGPT exposes OpenAI-compatible endpoints. Clawdbot registers it as the
+`nanogpt` provider.
+
+## Quick setup
+
+1) Set `NANOGPT_API_KEY` (or run the wizard below).
+2) Run onboarding:
+
+```bash
+clawdbot onboard --auth-choice nanogpt-api-key
+```
+
+The default model is set to:
+
+```
+nanogpt/zai-org/glm-4.7
+```
+
+## Config example
+
+```json5
+{
+  env: { NANOGPT_API_KEY: "sk-..." },
+  agents: {
+    defaults: {
+      model: { primary: "nanogpt/zai-org/glm-4.7" },
+      models: { "nanogpt/zai-org/glm-4.7": { alias: "GLM 4.7" } }
+    }
+  },
+  models: {
+    mode: "merge",
+    providers: {
+      nanogpt: {
+        baseUrl: "https://nano-gpt.com/api/v1",
+        apiKey: "${NANOGPT_API_KEY}",
+        api: "openai-completions",
+        models: [
+          {
+            id: "zai-org/glm-4.7",
+            name: "GLM 4.7",
+            reasoning: true,
+            input: ["text"],
+            cost: { input: 0, output: 0, cacheRead: 0, cacheWrite: 0 },
+            contextWindow: 200000,
+            maxTokens: 65535
+          }
+        ]
+      }
+    }
+  }
+}
+```
+
+## Notes
+
+- Model refs use `nanogpt/<modelId>`.
+- If you enable a model allowlist (`agents.defaults.models`), add every model you plan to use.
+- For the full provider catalog and configuration rules, see [Model providers](/concepts/model-providers).
