Description

When using the Ollama provider with ollama launch openclaw, the model runs successfully but produces no visible output to the user.

Steps to Reproduce

1. Install and run ollama serve as a systemd service
2. Sign in to Ollama cloud: ollama signin
3. Pull a cloud model: ollama run kimi-k2.5:cloud (works fine in CLI)
4. Configure OpenClaw: ollama launch openclaw
5. Select kimi-k2.5:cloud and confirm
6. Restart gateway: openclaw gateway restart
7. Switch model: /model kimi
8. Send a message: "tell me a joke"

Expected Behavior

The model should respond with output visible to the user.

Actual Behavior

• Logs show run completes successfully (durationMs=5236)
• No errors in logs
• User sees "(no output)"
• Session shows tokens used (47k/131k), confirming model ran
• Direct curl to Ollama API works fine: curl http://localhost:11434/v1/chat/completions returns proper responses

No errors, run completes normally but output never reaches the user.

}

Environment

• OpenClaw: 2026.2.1 (ed4529e)
• Node: v22.22.0
• OS: Linux 6.8.0-1044-aws (x64)
• Ollama: latest
• Model: kimi-k2.5:cloud (Ollama cloud model)

Workaround

Direct Ollama CLI usage works fine. Issue only affects OpenClaw integration.

Notes

Tried with both reasoning: true and reasoning: false. Same result.
Auth was initially missing (got No API key found for provider ollama error), added dummy key ollama-local which resolved auth error but output still doesn't appear.
