Ming-flash-omni 2.0

📑 Technical Report｜🤗 Hugging Face｜ 🤖 ModelScope

The newly released Ming-flash-omni 2.0 leverages the Ling-2.0 architecture—a Mixture-of-Experts (MoE) framework comprising 100B total and 6B active parameters. Representing a generational advancement over its predecessor, it establishes new State-of-the-Art (SOTA) benchmarks among open-source omni-MLLMs. Ming-flash-omni 2.0 effectively synergizes foundational abilities with specialized domain expertise. In particular, it exhibits superior performance in visual encyclopedic knowledge, immersive speech synthesis, and high-dynamic image generation and manipulation.

• [2026.02.11] 🔥 We release the official version of Ming-flash-omni 2.0, an open-source SOTA omni-MLLM that pushes the boundaries of multimodal understanding and synthesis.
• [2025.10.27] 🔥 We release the preview version of Ming-flash-omni：Ming-flash-omni Preview.
• [2025.07.15] 🔥 We release Ming-lite-omni v1.5 with significant improvements across all modalities.
• [2025.06.12] 🔥 Our Technical Report is in public on arxiv.
• [2025.05.28] 🔥 The official version of Ming-lite-omni v1 is released, with better performance and image generation support.
• [2025.05.04] 🔥 We release the test version of Ming-lite-omni：Ming-lite-omni-Preview.

Compared to Ming-flash-omni Preview, Ming-flash-omni 2.0 focuses on optimizing capabilities across the following key domains:

• Expert-level Multimodal Cognition: It accurately identifies plants and animals, recognizing cultural references (from regional cuisines to global landmarks), and delivering expert-level analysis of artifacts, including era, form, and craftsmanship. By synergizing high-resolution visual capture with a vast knowledge graph, the model achieves "vision-to-knowledge" synthesis, enabling superior knowledge understanding.

• Immersive and Controllable Unified Acoustic Synthesis: Ming-flash-omni 2.0 introduces a unified end-to-end acoustic generation pipeline that integrates Speech, Audio, and Music within a single channel. Leveraging Continuous Autoregression coupled with a Diffusion Transformer (DiT) head, the model enables zero-shot voice cloning and nuanced attribute control (e.g., emotion, timbre, and ambient atmosphere). This architecture facilitates a transition from simple text-to-speech to highly expressive, emotionally resonant, and immersive auditory experiences.

• High-Dynamic Controllable Image Generation and Manipulation: Ming-flash-omni 2.0 features a native multi-task architecture that unifies segmentation, generation, and editing, allowing for sophisticated spatiotemporal semantic decoupling. It excels in high-dynamic content creation, including atmospheric reconstruction, seamless scene composition, and context-aware object removal. By maintaining texture coherence and spatial depth consistency, Ming-flash-omni 2.0 achieves state-of-the-art precision in complex image manipulation tasks.
