Allow running request inside different model without changing of model

### Describe the feature or problem you'd like to solve

Allow running request inside different model without changing of model

### Proposed solution

Changing of model is cumbersome and global. I like to be able to daily drive for example Claude 4.5 Sonnet, and be able to do a quick request to Opus. Or, sometimes daily drive Opus, and send a quick request to Chat GPT mini (free). Many times between lots of complicated things you are tempted to ask a simple question for bridge.
