Subagent with specific model results in model change in build and plan mode #6636
Description
Description
When using a subagent with a specific model, it happens, with the current version (1.0.223), that the main models (build and plan) is also changed to the subagents model. This did not happen before. Is this intentional? Can I reset/configure this somehow?
OpenCode version
1.0.223
Steps to reproduce
- Start using Model A
- Trigger a subanget for which another model (Model B) is set in the config
- After the subagent finished, the Model B is also set for the main agents (build and plan)

This has also been happening to me with custom commands that use a different model than the main agent, even if the command is configured as a subtask or subagent.
