no, Routstr has no models. all the models you see are models that are relayed through Routstr. 
if you have configured OpenRouter separately, you can use openrouter/moonshotai/kimi-k2.5. But you can use the exact same model with just routstr/kimi-k2.5

<provider>/<model_id> is a format OpenClaw has adopted. Our model ids are just "kimi-k2.5" if you go to https://api.routstr.com/v1/models
