Hi @<1683648242530652160:profile|ApprehensiveSeaturtle9>

I send a request to the endpoint but never unload (the gpu memory keep increasing when I infer with a new model).

They are not unloaded after the request is done. see discussion here: None
You can however remove the model from the serving session (but I do not think this is what you meant)
I'm assuming you want to run multiple models on a single GPU with not enough memory ?
