Model Card for Model ID

Ross is an open-source multimodal-chatbot trained by fine-tuning Qwen2/Vicuna on multimodal instruction-following data. It is an auto-regressive language model, based on the transformer architecture. It is incorperated with an image reconstruction objective for enhanced multimodal comprehension capabilities.
