LatentQuant: Preserving the Policy-Facing Latent Contract under NVFP4 VAE Quantization
Recent world action models (WAMs) reuse pretrained video VAEs whose encoder latents directly condition downstream action policies. Quantization must therefore preserve not only reconstruction fidelity but also the policy-facing latent contract expected by the frozen policy.…
