Summary

After reinstalling and reconfiguring OpenClaw 2026.4.10 on macOS, Volcengine Coding Plan fails before reply because the documented model ref volcengine-plan/ark-code-latest is rejected as Unknown model.

Steps to reproduce

1. Install OpenClaw 2026.4.10 on macOS using npm global install and the mac app.
2. Configure local gateway and confirm openclaw gateway probe returns reachable=yes, connect=ok, rpc=ok.
3. Configure Volcengine auth using VOLCANO_ENGINE_API_KEY.
4. Set the default model to volcengine-plan/ark-code-latest.
5. Run openclaw models status --agent main --probe or try to chat.
6. Observe Unknown model: volcengine-plan/ark-code-latest.

Expected behavior

The documented Volcengine Coding Plan model ref volcengine-plan/ark-code-latest should be accepted and the agent should reply normally.

Actual behavior

The agent fails before reply with Unknown model: volcengine-plan/ark-code-latest.

openclaw models status --agent main --probe shows:

• Default (defaults): volcengine-plan/ark-code-latest
• Configured models (1): volcengine-plan/ark-code-latest
• Volcengine auth is present
• Probe result: Unknown model: volcengine-plan/ark-code-latest

In one earlier probe, volcengine/deepseek-v3-2-251201 also returned Unknown model.

OpenClaw version

2026.4.10 (44e5b62)

Operating system

macOS 26.4.1

Install method

npm global install + mac app

Model

volcengine-plan/ark-code-latest

Provider / routing chain

openclaw -> local gateway -> volcengine-plan

Additional provider/model setup details

Using Volcengine Coding Plan with VOLCANO_ENGINE_API_KEY.

Observed facts:

• openclaw config get gateway.mode returns local
• openclaw gateway probe returns reachable=yes, connect=ok, rpc=ok
• openclaw models status --agent main --probe shows auth for both volcengine and volcengine-plan
• auth source is environment variable VOLCANO_ENGINE_API_KEY
• default model is set to volcengine-plan/ark-code-latest

This is not a custom endpoint setup. This is model-name based usage for Volcengine Coding Plan.

Logs, screenshots, and evidence

`openclaw models status --agent main --probe` output:

Default (defaults): volcengine-plan/ark-code-latest
Fallbacks (0) (defaults): -
Configured models (1): volcengine-plan/ark-code-latest

Auth overview
- volcengine effective=profiles... api_key=1
- volcengine-plan effective=profiles... api_key=1
- source=env: VOLCANO_ENGINE_API_KEY

Auth probes
- volcengine/deepseek-v3-2-251201 -> Unknown model
- volcengine-plan/ark-code-latest -> Unknown model

User-visible error:
Agent failed before reply: Unknown model: volcengine-plan/ark-code-latest

Impact and severity

Affected: local macOS installation using Volcengine Coding Plan
Severity: High (blocks all normal chat replies with this provider)
Frequency: Always observed after configuration
Consequence: OpenClaw cannot reply when configured to use Volcengine Coding Plan
