Google Releases PaliGemma 2 Mix: An Open-Source Visual Language Model Supporting Multiple Tasks

Google has officially released PaliGemma 2 mix, a powerful multi-task visual language model. This model is the latest member of the Gemma series, capable of processing multiple visual-related tasks within a single model, including image description, optical character recognition (OCR), object detection, and image segmentation. PaliGemma 2 mix

Key Features

Multi-Task Support

PaliGemma 2 mix supports various visual tasks:

  • Image Description:Generates accurate and detailed image descriptions
  • Optical Character Recognition (OCR):Recognizes text content in images
  • Object Detection:Detects and locates objects in images
  • Image Segmentation:Performs precise semantic segmentation of images
  • Document Understanding:Understands and analyzes document image content
  • Open-Ended Visual Language Prompts:Supports flexible visual language interactions

Multiple Scale Options

To adapt to different application scenarios, the model offers three different scales:

  • 3B parameter version:Suitable for resource-constrained scenarios
  • 10B parameter version:Balances performance and resource consumption
  • 28B parameter version:Provides the best performance

Flexible Resolution Support

The model supports two image input resolutions:

  • 224px:Suitable for regular image processing tasks
  • 448px:Suitable for scenarios requiring higher detail

Developer-Friendly Features

  1. Framework Compatibility
