大型语言模型(LLMs)(OpenAI, 2022, 2023a;Anthropic, 2023;Google, 2023)的显著成功,激发了人们对能够处理语言之外多种模态的多功能接口的需求。为响应这一日益增长的需求,Large Multimodal Models(LMMs)相继涌现,例如 GPT-4V(OpenAI, 2023b)和 Gemini(Team et al., 2023)。这些模型作为多功能助手,能够理解并执行跨越 vision 与 language 的指令。这些模型在执行复杂、多样的真实世界任务方面展现出巨大潜力,使交互更加自然、更接近人类。 图 1:DeepSeek-VL 具备通用 multimodal 理解能力,可处理逻辑图、网页、公式识别、科学文献、自然图像以及复杂场景中的 embodied intelligence。 近期,开源 large multimodal models 大量涌现,旨在缩小与 proprietary 模型的差距。尤其在 benchmark 性能方面已取得 substantial 进展,但在真实世界性能与用户体验方面,大多数开源模型与 state-of-the-art closed-source 模型(OpenAI, 2023b;Bavishi et al., 2023;Team et al., 2023;Bai et al., 2023)之间仍存在显著鸿沟。开源社区仍难以开发具备 robust 通用 multimodal 能力、适用于真实世界应用的模型。大多数开源模型与 proprietary 模型之间的性能差距在真实世界场景中尤为突出,主要由于以下原因: • 许多开源方案将大量计算资源分配给 instruction tuning 阶段。然而,训练 powerful language models 的经验表明,extensive pretraining 在通用智能开发中至关重要。为使 multimodal models 具备丰富的世界知识,应当

1 Introduction
重视 comprehensive pretraining,充分利用广泛的 vision-language 数据。 • 常见做法是在 instruction tuning 期间合并各类学术数据集。虽然这种方法可能取得良好的 benchmark 结果,但往往难以提供真实的 real-world usage experience。 • 在模型架构方面,先前工作大多将 vision transformer(通常为 text-aligned)适配到预训练 language model 上。然而,这些模型大多在相对较低的分辨率下运行,例如 336×336 或 448×448。复杂真实世界场景(如 optical character recognition 或 tiny object discernment)的复杂性要求具备 high-resolution processing 能力。 • 尽管部分模型(Sun et al., 2023;Wang et al., 2023b;01-ai, 2024;Lin et al., 2023a)已开始利用 pretraining,它们往往忽视语言技能的保持。长时间 multimodal training 后,语言能力常出现退化。由于我们追求在两种模态上均具备强大能力的 generalist,因此在发展新模态能力时,应当采用能够良好保持 language capability 的训练策略。 基于上述考量,我们提出 DeepSeek-VL,这是一个基于 DeepSeek language model 系列构建的开源 large multimodal model。我们以 real-world scenarios 中的 adept 性能为目标进行开发,涉及 extensive pretraining、基于 use case taxonomy 的精细数据 curation、面向 high-resolution processing 的模型架构设计,以及平衡多模态的训练策略。在此基础上,我们开发了一套训练方法,以引导模型从 1B 扩展至 7B。与同规模的其他 LMMs 相比,这些全面探索在实际应用场景中带来了显著的性能优势。DeepSeek-VL 的预训练数据集汇编自多种来源,包括但不限于

而阶段 2 与阶段 3 的组合仍略低于阶段 1、阶段 2 和阶段 3 的组合性能,表明 vision-language adaptor warmup 阶段仍然具有重要意义。Modality Group Training 在混合 language 与 multimodal 数据时,我们观察到在 batch 级别直接混合会显著降低训练效率。这种低效源于每个 batch 的梯度反向传播过程需等待最慢样本完成。因此,处理速度通常更快的纯 language 数据不得不等待 multimodal 样本完成,导致整体训练效率下降。 图 8:modality warmup 在 language(Pile-test)与 multimodal(MMBench 和 MMBench_CN)benchmark 上的 comparative analysis 表明,modality grouping 在 language 任务上 consistently 优于 non-grouped modality 方法,同时在 training stage 2(Multimodal:Language=60%:40%)的 multimodal 任务上保持性能。为应对此问题,我们在每个 global step 对不同模态的数据进行分组,分别采样不同模态。该方法组织训练数据,使 batch 在不同训练步骤中完全由 language 数据或 multimodal 数据组成,而非在同一 batch 内混合。结果如图 8 所示,我们观察到该方法不损害模型性能,同时将训练效率提升 20%。该策略有效规避模态间处理时间差异造成的瓶颈,优化训练流程。Modality Warmup 鉴于我们的方法是在 language model 基础上进行 multimodal training,从一开始就按固定比例直接混合 multimodal 数据可能使模型不稳定。为应对此问题,我们提出一种简单 yet effective 的 modality warm-up 策略。Initially,我们将 language data ratio 设为 1,然后 gradually decrease 至 final model training 的 target ratio(例如 0.7)。Initially,我们将 language dat

[原文]theless, DeepSeek-VL-7B shows a certain degree of decline in mathematics (GSM8K), which suggests that despite efforts to promote harmony between vision and language modalities, there still exists a competitive relationship between them. This could be attributed to the limited model capacity (7B), and larger models might alleviate this issue significantly. Overall, DeepSeek-VL strives to achieve the goal of minimizing declines in language capability while addressing these challenges.
[原文]To further explore the capabilities of our DeepSeek-VL, we independently construct a dataset for manual evaluation. This dataset comprises 100 questions, divided into seven categories, each encompassing specific tasks. These categories and tasks are same as our taxonomy for the in-house SFT data, as shown in Table 3 . This approach ensures that the tasks we test are universal and encompass the majority of use cases for multimodal models. Moreover, based on the categories and tasks described in existing reports, we collect similar image materials and developed prompts. The sources for these ima...
[原文](Zheng et al., 2024 ) , we show GPT-4V the question and the answers from two different models and ask GPT-4V to determine which one is better or declare a tie. The results indicate a preference for DeepSeek-VL’s responses in the majority of cases, as GPT-4V tends to rate the quality of DeepSeek-VL’s answers more favorably. As illustrated in Figure 7 , DeepSeek-VL is judged to be superior in over 60% of instances when compared to open-source multimodal models, including Fuyu-8B, CogVLM-17B, and InternLM-XComposer2-VL. Moreover, in comparison with other proprietary models, such as GPT-4V itself,...

[原文]Scale Up Projector Training We expand the dataset for stage 1 (projector warmup) and subsequently apply supervised fine-tuning. The results, depicted in Figure 8 , demonstrate that augmenting the training data volume does not enhance performance at this stage. This implies that the projector’s capacity is inherently constrained, rendering it incapable of capturing the extensive knowledge necessary for multimodal tasks.

Figure 8: Comparative analysis of modality warmup on language (Pile-test) and multimodal (MMBench and MMBench _ _ \_ CN) benchmarks demonstrates that modality grouping consistently surpasses the non-grouped modality approach in language tasks, while simultaneously preserving performance on multimodal tasks on training stage 2 (Multimodal:Language=60%:40%). To address this issue, we experiment with grouping different modalities of data at each global step, sampling distinct modalities separately. This approach involves organizing the training data so that...

This gradual adaptation enables the model to more seamlessly adjust to the incorporation of multimodal data, thereby improving overall training stability and performance. Vision Encoder Selection In order to better acquire and utilize image information, we compare the training loss of different vision encoders under our training settings except for reducing training steps of stage 2 to 8000 for efficiency. As illustrated in Figure 10 , the incorporation of vision-only s...

[原文]In this technical report, we have introduced DeepSeek-VL, a series of Multimodal Large Language Models, available in scales of 1.3B and 6.7B parameters. This report has unveiled the limitations inherent in the predominant projector-based pretraining methodologies, setting the stage for the innovative approach adopted by DeepSeek-VL. By prioritizing a joint vision and language (VL) pretraining phase, DeepSeek-VL transcends traditional models by ensuring that the integration of multimodal data does not compromise the linguistic capabilities of the Large Language Models (LLMs). This is achieved t...
