Optimize models for large datasets

**Description**
Currently models lacks proper timeout support.

**Proposed solution**
Add configurable timeout with sensible defaults.

**Priority**: Low/Medium

No file, test, or entry point is named in the issue. Start by locating the model execution path and existing configuration handling, then determine how timeout values are passed and tested; done means a configurable timeout with sensible defaults is applied consistently.
