-## 🐶 JoyAI-Image
-
-JoyAI-Image is a **unified multimodal foundation model** for image understanding, text-to-image generation, and instruction-guided image editing. It combines an 8B Multimodal Large Language Model (MLLM) with a 16B Multimodal Diffusion Transformer (MMDiT). A central principle of JoyAI-Image is the **closed-loop collaboration between understanding, generation, and editing**. Stronger spatial understanding improves grounded generation and controllable editing through better scene parsing, relational grounding, and instruction decomposition, while generative transformations such as viewpoint changes provide complementary evidence for spatial reasoning.

-
-## 💎 Highlights
-
-- **Unified multimodal foundation**: one model family for understanding, generation, and editing through a shared MLLM-MMDiT interface.
-- **Practical data and training recipe**: a scalable pipeline with spatial understanding data ([OpenSpatial](https://github.com/VINHYU/OpenSpatial)), long-text rendering data, editing data, and multi-stage optimization strategies.
-- **Awakened spatial intelligence**: stronger spatial understanding, controllable spatial editing, and novel-view-assisted reasoning through a bidirectional loop between understanding and generation.
-- **Advanced visual generation**: strong long-text typography, layout fidelity, multi-view generation, and controllable editing with better preservation of scene structure.

-
-### Multi-view Generation and Spatial Editing Showcase
-
-JoyAI-Image showcases a spatially grounded generation and editing pipeline that supports multi-view generation, geometry-aware transformations, camera control, object rotation, and precise location-specific object editing. Across these settings, it preserves scene content, structure, and visual consistency while following viewpoint-sensitive instructions more accurately.

-
-### Spatial Editing for Spatial Reasoning Showcase
-
-JoyAI-Image poses high-fidelity spatial editing, serving as a powerful catalyst for enhancing spatial reasoning. Compared with Qwen-Image-Edit and Nano Banana Pro, JoyAI-Image-Edit synthesizes the most diagnostic viewpoints by faithfully executing camera motions. These high-fidelity novel views effectively disambiguate complex spatial relations, providing clearer visual evidence for downstream reasoning.
