New robot policy runs on an RTX 5090, beating OpenVLA-OFT while using 0.7% of its size

Jeff Cui shows that a frozen ViT backbone plus a tiny transformer can outperform a 7B‑parameter VLM in robot control.

Why it matters

Patch Policy proves that dense visual features from a frozen ViT can replace massive VLMs for robot control, dramatically cutting compute costs and latency while improving performance.

A lean visual policy beats a 7B‑parameter VLM

Jeff Cui (@jeffacce) announced on July 22nd, 2026 a new robot‑control method he calls Patch Policy. The approach freezes a state‑of‑the‑art Vision Transformer (ViT) pretrained on large‑scale image data, feeds every patch token to a lightweight transformer policy, and adds a simple block‑causal mask. The result, Cui writes, “beats OpenVLA‑OFT with 0.7% of its params, and trains on a 5090.”…
