Multimodal Vision Specifications

• Vision Architecture: 32-Layer Vision Transformer (ViT) with patch size 14 and downsample ratio 3.
• Lossless Preservation: Vision encoder weights (vision.*) and cross-attention projector (aligner.*) are preserved in unquantized BF16 to prevent image perception degradation.
• Native Context: 1,048,576 tokens YaRN context window.
