LLM-Drop

🤗 LLM-Drop hosts research artifacts for efficient foundation models, with a focus on large language models and unified multimodal models.

Our work studies how modern foundation models can be made more efficient while preserving their core capabilities. This page collects model weights, code links, project pages, and related resources from our research projects.
