+**Имеет смысл включать только при наличии в системе более одной видеокарты!**
+
+Кроме этого параметра должен быть включен параметр `use_library.enabled` и указана модель в `use_library.model`.
+
+Предположим, что указаны параметры модели `"use_library"."model": "model_name"` и устройства в `enabled_gpu_numbers: [0, 1]`.
+Тогда приложение при старте проверит, загружены ли в LM Studio модели `model_name--parallel-gpu#0` и `model_name--parallel-gpu#1`,
+если не загружены - попытается загрузить. Параметры загрузки указаны так, чтобы каждая модель приоритетна была загружена на соответсвующую видеокарту.
+
+Очень желательно, чтобы модели и их контекст полностью помещались в памяти видеокарты.
