What is imp-v1-3b?
imp-v1-3b is a groundbreaking multimodal small language model that combines the power of Microsoft's Phi-2 language model with Google's SigLIP visual encoder. Developed by MILVLG at Hangzhou Dianzi University, this model achieves remarkable performance despite its compact size, matching or exceeding the capabilities of larger 7B parameter models.
Implementation Details
The model leverages a hybrid architecture that integrates a 2.7B parameter language model (Phi-2) with a 0.4B parameter visual encoder (SigLIP). Trained on the LLaVA-v1.5 dataset, it processes both text and images efficiently in FP16 precision.
