Tsinghua’s Spatial‑TTT Beats Gemini: Continuous Spatial Intelligence Wins ECCV 2026

Spatial‑TTT, a 2‑billion‑parameter open‑source multimodal model, uses fast‑weight updates, a hybrid TTT architecture, a spatial‑predictive mechanism and dense 3D scene supervision to maintain and refresh a spatial memory while processing up to 120‑minute video streams, outperforming Gemini‑3‑pro and other closed‑source baselines on multiple spatial‑intelligence benchmarks with over 40% lower memory and compute cost.
