Bug: Forced 'anthropic/' prefix causes "Unknown model" error with local Ollama providers

[zizdoun4-afk]

Description

The agent automatically appends the anthropic/ prefix to models even when configured to use a local Ollama instance. This leads to a connection failure because Ollama does not recognize the prefixed model name.

Steps to Reproduce

1. Set up Ollama with qwen2.5-coder:7b.
2. Configure clawdbot.json with primary: "qwen2.5-coder:7b".
3. Run moltbot gateway.
4. Observe the logs.

Observed Logs

[clawdbot] Model "qwen2.5-coder:7b" specified without provider. Falling back to "anthropic/qwen2.5-coder:7b".
[diagnostic] lane task error: error="Error: Unknown model: anthropic/qwen2.5-coder:7b"

Expected Behavior

The agent should respect the baseUrl and not force a provider prefix if it's already defined or if a local provider is intended.

Environment

• Version: 2026.1.24-3
• OS: Windows
• LLM: Ollama (Local)

@zizdoun4-afk Did you tried these settings :

"agents": {
    "defaults": {
      "model": {
        "primary": "ollama/qwen3"
      },
      "models": {
        "ollama/qwen3": {}
      },
      "workspace": "/root/clawd",
      "compaction": {
        "mode": "safeguard"
      },
      "maxConcurrent": 4,
      "subagents": {
        "maxConcurrent": 8
      }
    }
  },

replace qwen3 by your targetted model

It works fine on my computer with clawdbot 2026.1.24-3

I'm having a similar issue with text-generation-webui:

I've this agent configuration, but the LLM never gets triggered:

"agents": {
    "defaults": {
      "model": {
        "primary": "Oobabooga/Qwen3-30B-A3B-Thinking-2507"
      },
      "models": {
        "Oobabooga/Qwen3-30B-A3B-Thinking-2507": {}
      },
      "workspace": "/root/.openclaw/workspace",
      "compaction": {
        "mode": "safeguard"
      },
      "heartbeat": {
        "model": "Oobabooga/Qwen3-30B-A3B-Thinking-2507",
        "includeReasoning": true
      },
      "maxConcurrent": 4,
      "subagents": {
        "maxConcurrent": 8
      }
    },
    "list": [
      {
        "id": "main"
      },
      {
        "id": "default",
        "name": "default",
        "workspace": "/root/.openclaw/workspace-default",
        "agentDir": "/root/.openclaw/agents/default/agent"
      }
    ]
  },

But auth probes return an ok on the command line.
