Add rate limiting for timeout

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

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

**Priority**: Low/Medium

The issue does not name any files, tests, or entry points. First clarify whether the intended work is rate limiting for timeouts or configurable model import, then locate the relevant model-handling entry point and define the defaults, configuration interface, and tests that establish completion.
