Finetuning llm model using Trainer and reusing it

Hi , I am new to llm finetuning . Recently I finetuned a llama-7b model on custom data for question answering .
After training I saved the model using “model.save_pretrained(OUTPUT_DIR)” command . But in the OUTPUT_DIR I got two files adapter_config.json and “adapter_model.bin” file . I dont know how to use it to reload the model . Also finding difficulty in further using the model for text generation . Can anyone help here ?
