Сжатие контекста (Context Compression)

+
Автоматическое сжатие длинного контекста с сохранением 100% технических фактов и сущностей
+
+ Н/Д: модель для сжатия не выбрана +
+
+
+
Профиль модели для сжатия
+
Служебная модель-компрессор (например, Qwen3-4B на порту 8082). Не участвует в маршрутизации Hermes.
+
+
+ +
+
+
+
+
Порог заполнения контекста для запуска сжатия
+
Сжатие начинается при превышении процента от измеренного контекста модели (/props)
+
+
+ +
+
+
+
+
Количество свежих сообщений (Fresh Window)
+
Последние сообщения, которые всегда остаются 100% дословными и не подлежат сжатию
+
+
+ +
+
+
+
+
Диагностика и проверка сжатия
+
Проверить отклик компрессора и 100% удержание путей, портов, IP и хэшей
