Recent AIGC advances have rapidly expanded from text-to-image generation toward high-quality multimodal synthesis across video and audio.
Within this context, joint audio-video generation (JAVG) has emerged as a fundamental task that produces synchronized and semantically aligned
sound and vision from textual descriptions. However, compared with advanced commercial models such as Veo3, existing open-source methods still
suffer from limitations in generation quality, temporal synchrony, and alignment with human preferences. To bridge the gap, this paper presents
<strong>JavisDiT++</strong>, a concise yet powerful framework for efficient and effective JAVG. First, we introduce a modality-specific mixture-of-experts
(MS-MoE) design that enables cross-modal interaction efficacy while enhancing single-modal generation quality. Then, we propose a temporal-aligned
RoPE (TA-RoPE) strategy to achieve explicit, frame-level synchronization between audio and video tokens. Besides, we develop an audio-video direct
preference optimization (AV-DPO) method to align model outputs with human preference across quality, consistency, and synchrony dimensions. Built upon
Wan2.1-1.3B-T2V, our model achieves state-of-the-art performance merely with around 1M public training entries, significantly outperforming prior
approaches in both qualitative and quantitative evaluations. Comprehensive ablation studies have been conducted to validate the effectiveness of
our proposed modules.

<p>
We propose a unified and efficient DiT architecture that jointly models
audio and video tokens via full self-attention to enable dense cross-modal interaction.
Modality-specific FFNs are then introduced to refine intra-modal features.
Unlike dual-stream frameworks or dynamic routing rules, our MS-MoE deterministically routes tokens by modality,
isolating interference while retaining the benefits of expert sparsity.
As a result, the model capacity is expanded (1.3B → 2.1B) without increasing inference cost.

<br>
<p>
We then propose a temporally aligned rotary position encoding (TA-RoPE) scheme that
temporally aligns audio and video tokens by assigning shared time indices, and offsets spatial dimensions to prevent overlap.
This alignment is achieved purely through position ID manipulation without physically reordering tokens,
avoiding the inefficiency of interleaving audio-visual tokens in autoregressive models.

<p>
We further propose the AV-DPO technique to improve audio-video quality and synchronization
by aligning generation with human preferences. It leverages diverse reward models to rank outputs and
construct preference pairs based on modality-aware criteria, ensuring consistent selection across modalities.
To our knowledge, this is the first application of preference alignment in the JAVG domain.
