+summary: "Use Modelverse (UCloud) as an OpenAI-compatible model provider in Clawdbot"
+read_when:
+  - You want to use Modelverse models in Clawdbot
+  - You need the base URL, API key setup, and model refs for Modelverse
+---
+# Modelverse
+
+Modelverse (UCloud) exposes an **OpenAI-compatible** API that can route to multiple model families.
+
+## Authenticate
+
+Get an API key:
+https://console.ucloud-global.com/modelverse/experience/api-keys
+
+Then run:
+
+```bash
+clawdbot onboard --auth-choice modelverse-api-key
+```
+
+This stores the key in Clawdbot's auth profiles and writes a `models.providers.modelverse` entry.
+
+## Model refs
+
+Use `modelverse/<modelId>`:
+
+- `modelverse/gpt-5.2`
+- `modelverse/claude-opus-4-5-20251101`
+- `modelverse/claude-sonnet-4-5-20250929`
+- `modelverse/deepseek-ai/DeepSeek-V3.2`
+- `modelverse/deepseek-ai/DeepSeek-R1`
+- `modelverse/deepseek-ai/DeepSeek-V3-0324`
+- `modelverse/openai/gpt-4o`
+- `modelverse/zai-org/glm-4.7`
+- `modelverse/gemini-3-flash-preview`
+- `modelverse/gemini-3-pro-preview`
+- `modelverse/gemini-2.5-flash`
+- `modelverse/gemini-2.5-pro`
+
+Switch models with:
+
+```bash
+clawdbot models set modelverse/gpt-5.2
+```
+
+## Config snippet (manual)
+
+```json5
+{
+  env: { MODELVERSE_API_KEY: "sk-..." },
+  agents: { defaults: { model: { primary: "modelverse/gpt-5.2" } } },
+  models: {
