# LLoCO: Learning Long Contexts Offline
[**Paper**](https://arxiv.org/abs/2404.07979) | [**Code**](https://github.com/jeffreysijuntan/lloco)
Lloco-7b-hqa is the LoRA adaptor checkpoint finetuned from [AutoCompressor-Llama-2-7b-6k](https://huggingface.co/princeton-nlp/AutoCompressor-Llama-2-7b-6k/) and [meta-llama/Llama-2-7b-hf](https://huggingface.co/meta-llama/Llama-2-7b-hf)
using the **LLoCO** method in [LLoCO: Learning Long Contexts Offline](https://arxiv.org/abs/2404.07979). It is instruction-tuned on the HotpotQA training set.
**LLoCO** enables LLMs to process long-context efficiently by learning contexts offline through context compression and in-domain parameter-efficient finetuning with LoRA. This approach extends the effective context window of a 4k token LLaMA2-7B model to handle up to 128k tokens, while using
30x fewer tokens and achieving up to 7.62x inference speed-up.
