Abstract: We present HunyuanImage 3.0, a native multimodal model that unifies
multimodal understanding and generation within an autoregressive framework,
with its image generation module publicly available. The achievement of
HunyuanImage 3.0 relies on several key components, including meticulous data
curation, advanced architecture design, a native Chain-of-Thoughts schema,
progressive model pre-training, aggressive model post-training, and an
efficient infrastructure that enables large-scale training and inference. With
these advancements, we successfully trained a Mixture-of-Experts (MoE) model
comprising over 80 billion parameters in total, with 13 billion parameters
activated per token during inference, making it the largest and most powerful
open-source image generative model to date. We conducted extensive experiments
and the results of automatic and human evaluation of text-image alignment and
visual quality demonstrate that HunyuanImage 3.0 rivals previous
state-of-the-art models. By releasing the code and weights of HunyuanImage 3.0,
we aim to enable the community to explore new ideas with a state-of-the-art
foundation model, fostering a dynamic and vibrant multimodal ecosystem. All
