The core challenge is not simply longer context windows but how spatial information is selected, organized, and retained over time.

In this paper, we propose Spatial-TTT towards streaming visual-based spatial intelligence with test-time training (TTT), which adapts a subset of parameters ( fast weights ) to capture and organize spatial evidence over long-horizon scene videos .

Extensive experiments demonstrate that Spatial-TTT improves long-horizon spatial understanding and achieves state-of-the-art performance on video spatial benchmarks .

The summary does not include concrete numbers, so the practical size of the gain and the tradeoff against latency or data cost are still unclear.

Sparse attention addresses this challenge effectively, and DeepSeek Sparse Attention (DSA) is a representative production-grade solution: a lightweight lightning indexer selects the top-k most relevant tokens per query, reducing core attention from O(L^2)...

We present IndexCache, which exploits this cross-layer redundancy by partitioning layers into a small set of Full layers that run their own indexer s and a majority of Shared layers that simply reuse the nearest Full layer's top-k indices.

IndexCache reduces sparse attention computation in large language models by reusing top-k token selections across layers, achieving significant speedups with minimal quality loss.

Existing agents have made remarkable progress in many domains, yet they still struggle to complete long-horizon tasks in an open world.

In this paper, we propose a Hybrid Multimodal Memory module to address the above challenges.

Extensive experimental results show that Optimus-1 significantly outperforms all existing agents on challenging long-horizon task benchmarks, and exhibits near human-level performance on many tasks.

The abstract is promising, but we still need to inspect the full paper for compute cost, implementation complexity, and how broadly the gains transfer beyond the reported benchmarks.
