Janus-Pro - DeepSeek's open-source unified multimodal model

What is Janus-Pro?

Janus-Pro is an open-source AI model from DeepSeek that supports image understanding and image generation, offering both 1B and 7B scales to suit diverse application scenarios. Through improved training strategies, expanded datasets, and larger-scale models, it significantly enhances text-to-image generation capabilities and instruction-following performance. Janus-Pro employs a decoupled visual encoding path, improving the flexibility of multimodal tasks and demonstrating high stability and accuracy in image generation tasks, making it a powerful unified multimodal model.

Main features of Janus-Pro

• Multimodal understanding and generationIt supports generating images from text (text-to-image), and can understand and process image content. It generates images that meet the requirements based on text descriptions, parses the images, and generates relevant text or tags.
• Open source and large-scale modelsIt provides multiple versions of the model (such as 1B and 7B), which developers and researchers can use freely and perform secondary development.
• Improved training strategies and datasetsThrough an improved training strategy, Janus-Pro demonstrates greater stability and efficiency in multimodal tasks. It utilizes a large-scale training dataset covering a wider range of scenarios, enhancing the model's understanding and generation quality.
• Decoupling the visual encoding pathBy decoupling the encoding paths of visual and textual information, conflicts in visual and linguistic information processing are avoided, improving the flexibility and scalability of the model and enabling it to better handle complex multimodal tasks.
• Image-to-text instruction followIt can generate relevant text descriptions based on image content, or execute tasks according to instructions. For example, it can generate corresponding text descriptions based on an image, or process images according to instructions.
• High-efficiency image generation capabilityIt excels in text-to-image generation tasks, producing high-quality images based on input text descriptions. The generated images possess high realism and detail, meeting complex requirements.
• Multi-task learning and reasoningIt supports multi-task learning and can handle multiple tasks simultaneously, such as image generation, image understanding, and cross-modal reasoning. Its reasoning capabilities are very powerful, providing accurate results across multiple domains and tasks.

The technical principles of Janus-Pro

• Visual coding decouplingJanus-Pro handles multimodal understanding and generation tasks separately based on independent paths, effectively resolving the functional conflict between the two tasks of the visual encoder.
• Unified Transformer ArchitectureUsing a single Transformer architecture to handle multimodal tasks simplifies model design and enhances scalability.
• Optimized training strategyJanus-Pro has fine-tuned the training strategy, including extending the training on the ImageNet dataset, focusing on training on text-to-image data, and adjusting the data ratio.
• Expanded training dataJanus-Pro expands the scale and diversity of training data, including multimodal understanding data and visual generation data.
• Innovation of visual encodersJanus-Pro is based on SigLIP-L as a visual encoder, supporting high-resolution input and capturing image details.
• Innovation in generation modulesUsing the LlamaGen Tokenizer with a downsampling rate of 16, a more refined image is generated.
• Infrastructure innovationBuilt on the DeepSeek-LLM-1.5b-base/DeepSeek-LLM-7b-base model, it provides powerful multimodal processing capabilities.
