Dropping the Encoder
SenseTime's SenseNova-U1 open-sources a unified multimodal model that removes both the visual encoder and VAE — the two architectural crutches that every major multimodal system has relied on since the CLIP era. The NEO-unify architecture processes pixels natively through a shared transformer backbone, with a direct pixel-space MLP head for generation. Benchmarks on image generation and interleaved content put it at or above current open-source leaders, with the spatial reasoning numbers being the most credible differentiator.
