Sparse Autoencoder Achieves 128x Byte Reduction on Vision Wormhole Latent Tensors with 0.08pp Accuracy Drop

Post-hoc sparse coding compresses latent VLM agent communication 128x at negligible accuracy cost. The work demonstrates strong redundancy in dense tensor exchanges but leaves causal isolation of sparsity effects for follow-up studies. Findings support adaptive, content-dependent payloads in multi-agent systems.

Next steps include matched dense-versus-sparse trials and integration with existing VLM agent frameworks to test whether the 50-feature regime generalizes beyond the reported nine benchmarks.

⚡ Prediction

Di Wu: Matched-payload experiments will show sparse coding contributes at least 4x additional compression beyond int8 quantization on three or more benchmarks within 9 months.
