Janus-Series - AI Vision Models Tool

Overview

Janus-Series is an open-source multimodal model suite from deepseek-ai that unifies understanding and generation capabilities in a single codebase. The project publishes multiple model variants — Janus, Janus-Pro, and JanusFlow — targeting tasks that span visual understanding and text-to-image generation. A core design goal is to decouple visual encoding from downstream stages, which improves flexibility for swapping or upgrading visual backbones without reworking the whole model. The repository also incorporates advanced generative techniques such as rectified flow to improve text-to-image synthesis quality. According to the GitHub repository, Janus has attracted substantial community attention (see GitHub analysis below), and the project is distributed under an MIT license, enabling permissive reuse. Janus-Series is suitable for research and engineering workflows that need a unified multimodal stack with modular visual encoders and improved generation components.
