DeepSeek Open-Sources DeepSeek-V4-Flash-Vision-Exp Multimodal Model
DeepSeek has open-sourced DeepSeek-V4-Flash-Vision-Exp, its first V4-series multimodal model featuring image input capabilities under the MIT license. The model supports image description, text recognition in screenshots, and chart analysis. This release provides the open-source community with strong multimodal agent capabilities that approach proprietary models like Opus-4.8. It enables developers to integrate visual understanding into diverse agent frameworks for practical workflows. The release includes model files, a tokenizer, prompt encoding references, and a minimal PyTorch inference implementation. It covers core modules such as the visual encoder, Aligner, DFlash Attention, MoE, Hyper-Connections, and DSpark.
## BACKGROUND
DeepSeek is an AI research company known for highly efficient open-source models. This release utilizes advanced architectures like Mixture of Experts (MoE), Hyper-Connections (which optimize residual connections in deep networks), and DSpark, an inference acceleration framework designed to speed up large language models.
