Janus-4o is a multimodal large language model (MLLM) capable of both **text-to-image** and **text-and-image-to-image** generation. It is fine-tuned from [Janus-Pro-7B](https://huggingface.co/deepseek-ai/Janus-Pro-7B) using the [ShareGPT-4o-Image](https://huggingface.co/datasets/FreedomIntelligence/ShareGPT-4o-Image) dataset to align Janus-Pro with GPT-4o image generation capabilities. Compared to Janus-Pro, Janus-4o newly supports text-and-image-to-image generation capabilities, along with notable improvements in text-to-image tasks.

> ⚠️ **Statement**: **ShareGPT-4o-Image** is a distilled dataset from GPT-4o-Image, offering 4o-level data quality (_referring to data, not model capability_). **Janus-4o** is a fine-tuned version of Janus-Pro on this dataset, with added image editing support. Fine-tuning brings noticeable gains in image generation, but **Janus-4o still lags behind GPT-4o-Image in overall performance**.
