Consider deprecating old api API

**Feature request**
It would be great to have timeout for models.

**Use case**
Many users need this functionality for production deployments.

**Implementation idea**
Add a new config option `enable_timeout` with default `false`.

The issue does not name any files, tests, or entry points. Start by locating model configuration and the existing API configuration path, then clarify whether the goal is API deprecation, model timeouts, or both. Before implementation, define how enable_timeout=false behaves, where the timeout applies, and which tests should establish completion.
