It's not a trimming issue but openai by default sets the tool call to true, the free model from the openrouter doesn't support the tool call that's why it's erroring out. Technically like ollama and mistral we should have setting to enable and disable tool call for custom models.

OpenRouter is not currently supported. Perhaps soon:
