Ming-flash-omni-2.0: Model Card

Technical Report｜Hugging Face｜ModelScope ## Introduction The newly released Ming-flash-omni 2.0 leverages the [Ling-2.0](https://github.com/inclusionAI/Ling-V2) 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.

## Updates * [2026.02.11] We release the official version of [Ming-flash-omni 2.0](https://mp.weixin.qq.com/s/hz2fsH1DGpp2zpY-Yngsog), 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](https://github.com/inclusionAI/Ming/tree/main). * [2025.07.15] We release [Ming-lite-omni v1.5](https://github.com/inclusionAI/Ming/tree/v1.5) with significant improvements across all modalities. * [2025.06.12] Our [Technical Report](https://arxiv.org/abs/2506.09344) is in public on arxiv. * [2025.05.28] The official version of [Ming-lite-omni v1](https://github.com/inclusionAI/Ming/tree/v1.0) 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](https://github.com/inclusionAI/Ming/tree/Ming-Lite-Omni-Preview). ## Key Features Compared to [Ming-flash-omni Preview](https://github.com/inclusionAI/Ming/tree/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.
