# Volcengine (Doubao)
The Volcengine provider gives access to Doubao models and third-party models
hosted on Volcano Engine, with separate endpoints for general and coding
workloads.
- Providers: `volcengine` (general) + `volcengine-plan` (coding)
- Auth: `VOLCANO_ENGINE_API_KEY`
- API: OpenAI-compatible
## Quick start
1. Set the API key:
```bash
openclaw onboard --auth-choice volcengine-api-key
```
2. Set a default model:
```json5
{
agents: {
defaults: {
model: { primary: "volcengine-plan/ark-code-latest" },
},
},
}
```
## Non-interactive example
```bash
openclaw onboard --non-interactive \
--mode local \
--auth-choice volcengine-api-key \
--volcengine-api-key "$VOLCANO_ENGINE_API_KEY"
```
## Providers and endpoints
| Provider | Endpoint | Use case |
| ----------------- | ----------------------------------------- | -------------- |
| `volcengine` | `ark.cn-beijing.volces.com/api/v3` | General models |
| `volcengine-plan` | `ark.cn-beijing.volces.com/api/coding/v3` | Coding models |
Both providers are configured from a single API key. Setup registers both
automatically.
## Available models
General provider (`volcengine`):
| Model ref | Name | Input | Context |
| -------------------------------------------- | ------------------------------- | ----------- | ------- |
| `volcengine/doubao-seed-1-8-251228` | Doubao Seed 1.8 | text, image | 256,000 |
| `volcengine/doubao-seed-code-preview-251028` | doubao-seed-code-preview-251028 | text, image | 256,000 |
| `volcengine/kimi-k2-5-260127` | Kimi K2.5 | text, image | 256,000 |
| `volcengine/glm-4-7-251222` | GLM 4.7 | text, image | 200,000 |
| `volcengine/deepseek-v3-2-251201` | DeepSeek V3.2 | text, image | 128,000 |
Coding provider (`volcengine-plan`):
| Model ref | Name | Input | Context |
| ------------------------------------------------- | ------------------------ | ----- | ------- |
| `volcengine-plan/ark-code-latest` | Ark Coding Plan | text | 256,000 |
| `volcengine-plan/doubao-seed-code` | Doubao Seed Code | text | 256,000 |
| `volcengine-plan/glm-4.7` | GLM 4.7 Coding | text | 200,000 |
| `volcengine-plan/kimi-k2-thinking` | Kimi K2 Thinking | text | 256,000 |
| `volcengine-plan/kimi-k2.5` | Kimi K2.5 Coding | text | 256,000 |
| `volcengine-plan/doubao-seed-code-preview-251028` | Doubao Seed Code Preview | text | 256,000 |
`openclaw onboard --auth-choice volcengine-api-key` currently sets
`volcengine-plan/ark-code-latest` as the default model while also registering
the general `volcengine` catalog.
During onboarding/configure model selection, the Volcengine auth choice prefers
both `volcengine/*` and `volcengine-plan/*` rows. If those models are not
loaded yet, OpenClaw falls back to the unfiltered catalog instead of showing an
empty provider-scoped picker.
## Environment note
If the Gateway runs as a daemon (launchd/systemd), make sure
`VOLCANO_ENGINE_API_KEY` is available to that process (for example, in
`~/.openclaw/.env` or via `env.shellEnv`).
