📄 Description

This change adds a new keep_alive parameter to /api/generate which can control the duration for how long a model is loaded and left in memory. There are three cases:

  1. if keep_alive is not set, the model will stay loaded for the default value (5 minutes);
  2. if keep_alive is set to a positive duration (e.g. "20m"), it will stay loaded for the duration;
  3. if keep_alive is set to a negative duration (e.g. "-1m"), it will stay loaded indefinitely

If you wish the model to be loaded immediately after generation, you can set it to "0m", or even just 0. Also, maybe most importantly, subsequent calls to the /api/generate will change the load duration, so even if you called it once with a negative value and the next caller omits it, it will still only stay in memory for 5 minutes after the second call.

Note that this change only applies to the /api/generate. We can either layer on the changes for /api/chat on top of this change, or push it as a separate PR.

resolves #1339
