Janus combines multimodal understanding and image generation models in a unified model series.
About Janus / Janus-Pro
Janus is an open source GitHub repository from DeepSeek that publishes the Janus-Series, a set of unified models for multimodal understanding and image generation. The series includes Janus, JanusFlow, and Janus-Pro. Janus-Pro is described as an advanced version of Janus, with an optimized training strategy, expanded training data, and larger model size. The source states that it improves both multimodal understanding and text-to-image instruction following. Model checkpoints are listed at 1.3B parameters for Janus and JanusFlow and at 1B and 7B for Janus-Pro, with a sequence length of 4096.
The repository provides Python code, installed with pip install -e on Python 3.8 or later. It includes inference scripts, an interactive chat script, and a technical report for Janus-Pro. Use of the models is subject to the terms in the License section, and the source states that commercial usage is permitted under those terms. Online demos are linked for Janus-Pro-7B, Janus, and JanusFlow. The source does not list hardware requirements.
Key features
- Unified models that handle both image understanding and image generation.
- Janus-Pro-1B and Janus-Pro-7B model checkpoints available on Hugging Face.
- JanusFlow variant that uses rectified flow for image generation.
- Janus variant that separates visual encoding into distinct pathways within one transformer.
- Gradio demo released for both online and local use.
- Evaluation code for reproducing multimodal understanding results in VLMEvalKit.
Best for: Machine learning researchers and developers who want to study, run, or build on unified multimodal understanding and image generation models.
Good for
