VLMs have grow to be central to constructing general-purpose AI techniques able to understanding and interacting in digital and real-world settings. By integrating visible and textual knowledge, VLMs have pushed developments in multimodal reasoning, picture modifying, GUI brokers, robotics, and extra, influencing sectors like training and healthcare. Regardless of this progress, VLMs nonetheless lag behind human capabilities, significantly in duties involving 3D reasoning, object counting, artistic visible interpretation, and interactive gameplay. A problem lies within the shortage of wealthy, various multimodal datasets, in contrast to the plentiful textual assets obtainable to LLMs. Moreover, multimodal knowledge complexity poses important coaching and analysis hurdles.
Researchers at ByteDance have developed Seed1.5-VL, a compact but highly effective vision-language basis mannequin that includes a 532 M-parameter imaginative and prescient encoder and a 20 B-parameter Combination-of-Consultants LLM. Regardless of its environment friendly structure, Seed1.5-VL achieves high outcomes on 38 out of 60 public VLM benchmarks, excelling in duties like GUI management, video understanding, and visible reasoning. It’s skilled on trillions of multimodal tokens utilizing superior knowledge synthesis and post-training strategies, together with human suggestions. Improvements in coaching, resembling hybrid parallelism and imaginative and prescient token redistribution, optimize efficiency. The mannequin’s effectivity and robust reasoning capabilities swimsuit real-world interactive functions like chatbots.
The Seed1.5-VL structure contains a imaginative and prescient encoder, an MLP adapter, and an LLM. Its customized imaginative and prescient encoder, Seed-ViT, helps native-resolution picture enter utilizing 2D RoPE and processes photographs by means of 14×14 patches, adopted by common pooling and an MLP. Pretraining entails masked picture modeling, contrastive studying, and omni-modal alignment utilizing photographs, textual content, and video-audio-caption pairs. The mannequin makes use of a Dynamic Body-Decision Sampling method for video encoding that adapts body charges and resolutions based mostly on content material complexity, balancing effectivity and element. This technique permits efficient spatial-temporal understanding inside a token funds, guaranteeing complete video illustration throughout different lengths and complexities.
The pre-training of Seed1.5-VL concerned curating 3 trillion high-quality tokens throughout various domains. Picture-text pairs from the net had been filtered utilizing CLIP scores, dimension/side ratio checks, and deduplication to scale back noise. Utilizing domain-based sampling and duplication methods, uncommon visible ideas had been overrepresented to handle class imbalance. Specialised datasets had been added for OCR utilizing annotated and artificial text-rich photographs, charts, and tables—object grounding and counting duties utilized bounding containers, factors, and auto-labeled internet knowledge. Extra duties included 3D spatial understanding utilizing depth annotations, and video understanding by means of multi-frame captioning, QA, and temporal grounding to assist dynamic content material evaluation.
The analysis highlights Seed-ViT and Seed1.5-VL’s aggressive efficiency throughout vision-language duties. Seed-ViT, regardless of having considerably fewer parameters, matches or outperforms bigger fashions like InternVL-C and EVA-CLIP on zero-shot picture classification duties, displaying excessive accuracy and robustness on datasets resembling ImageNet-A and ObjectNet. Seed1.5-VL demonstrates robust capabilities in multimodal reasoning, normal VQA, doc understanding, and grounding. It achieves state-of-the-art benchmarks, significantly in advanced reasoning, counting, and chart interpretation duties. The mannequin’s “pondering” mode, which contains longer reasoning chains, additional enhances efficiency, indicating its robust skill in detailed visible understanding and job generalization.
In conclusion, Seed1.5-VL is a vision-language basis mannequin that includes a 532 M-parameter imaginative and prescient encoder and a 20 B-parameter Combination-of-Consultants language mannequin. Regardless of its compact dimension, it achieves state-of-the-art outcomes on 38 of 60 public benchmarks and excels in advanced reasoning, OCR, diagram interpretation, 3D spatial understanding, and video evaluation. It additionally performs properly in agent-driven duties like GUI management and gameplay, surpassing fashions like OpenAI CUA and Claude 3.7. The mannequin reveals robust generalization to duties past its coaching scope. The examine outlines its structure, knowledge pipeline, and coaching strategies and identifies future instructions, together with enhancing tool-use and visible reasoning capabilities.
