LLoCO: Learning Long Contexts Offline

Paper | Code

Lloco-7b-quality is the LoRA adaptor checkpoint finetuned from AutoCompressor-Llama-2-7b-6k and meta-llama/Llama-2-7b-hf using the LLoCO method in LLoCO: Learning Long Contexts Offline. It is instruction-tuned on the QuALITY 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.
