 ### Model Architecture
 ZAYA1-VL-8B builds upon and uses our [ZAYA1-8B LLM](https://huggingface.co/Zyphra/ZAYA1-base) as its base text decoder. We also use the [Qwen2.5-VL vision encoder](https://huggingface.co/docs/transformers/model_doc/qwen2_5_vl) for the ViT. ZAYA1-VL-8B introduces two novel architectural innovations:
 * **Vision-specific LoRA parameters**: ZAYA1-VL-8B utilizes specialized LoRA parameters on its MLPs and CCA weights which are only activated on vision tokens. We find that adding vision-specific parameters substantially improves model performance since the model has the option to devote specific parameters solely to visual processing. We train these LoRA parameters alongside the main model parameters during training.
 * **Bidirectional Attention for image tokens**: ZAYA1-VL-8B processes all image token inputs with a bidirectional attention mask, meaning attention is not causal across an image. We find that this improves performance by not imposing an arbitrary causal order to image tokens which are naturally non-causal.

 ZAYA1-VL-8B is trained only upon open data. Detailed dataset descriptions can be found in the accompanying technical report.
 ## Performance
 ZAYA1-VL-8B performs extremely strongly against models of a comparable size and inference flops including outperforming several strong larger models.
