Introduction
Valley is a cutting-edge multimodal large model designed to handle a variety of tasks involving text, images, and video data, which is developed by ByteDance. Our model
- Achieved the best results in the inhouse e-commerce and short-video benchmarks, much better then other SOTA opensource models.
- Demonstrated comparatively outstanding performance in the OpenCompass Benchmark.
Release
- [2025/10/26] 🔥🔥🔥 Update Valley3, significantly enhance multimodal understanding and reasoning capabilities, achieving 74.4 on OpenCompass Multi-modal Academic Leaderboard!
- [2025/02/15] 🔥 Update Valley2-DPO, achieve 69.6 on OpenCompass Multi-modal Academic Leaderboard and update AutoModel usage for checkpoints.
- [2025/01/13] 🔥 Release TechReport. Valley2: Exploring Multimodal Models with Scalable Vision-Language Design
- [2024/12/23] 🔥 Announcing Valley2 (Valley-Eagle-7B)!
Architecture
The foundational version of Valley2 is a multimodal large model aligned with Siglip and Qwen2.5, incorporating LargeMLP and ConvAdapter to construct the projector.
- In the final version, we also referenced Eagle, introducing an additional VisionEncoder that can flexibly adjust the number of tokens and is parallelized with the original visual tokens.
- This enhancement supplements the model’s performance in extreme scenarios, and we chose the Qwen2vl VisionEncoder for this purpose.
The model structure is shown as follows:
