PaliGemma

GoogleOpen WeightsPending Human Review

PaliGemma is an open-weight vision-language model intended for task-specific fine-tuning. It combines a SigLIP visual encoder and Gemma text decoder, accepting images and text and generating text or structured tokens. Applications include captioning, visual question answering, OCR, detection, and segmentation. Pre-trained checkpoints at multiple image resolutions and task-mixture fine-tunes share this catalog page; it is not positioned as a general multi-turn chat assistant.
