Comparison

Meta VGGT accepts one to hundreds of images and predicts cameras, depth, point maps, and tracks in one feed-forward pass. LingBot-Map uses streaming state, KV cache, keyframes, and window resets for longer sequences. VGGT fits short batches and multi-task geometry; LingBot-Map targets continuous video and long-sequence state.
