This is often achieved by prepending informative passages of text, or ‘contexts’, retrieved from external knowledge bases to their input. However, processing addi\u0002tional contexts online incurs significant computation costs that scale with their length. State Space Models (SSMs) offer a promising solution by allowing a database of contexts to be mapped onto fixed-dimensional states from which to start the generation. A key challenge arises when attempting to leverage infor\u0002mation present across multiple contexts, since there is no straightforward way to condition generation on multiple independent states in existing SSMs. To address this, we leverage a simple mathematical relation derived from SSM dynamics to compose multiple states into one that..."}],"related_signals":[{"id":"a2cf1a37-dd65-4168-b2c6-093eb16cb60f","url":"https://onlylabs.fyi/signals/a2cf1a37-dd65-4168-b2c6-093eb16cb60f","source_url":"https://www.amazon.science/blog/graph-centric-agentic-intelligence","title":"Graph-centric agentic intelligence","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"amazon","name":"Amazon (Nova)","category":"frontier-lab"},"occurred_at":"2026-10-01T12:54:31+00:00","first_seen_at":"2026-10-01T20:00:49.441989+00:00","date_source":"rss.item_date"},{"id":"af78f536-671b-45a1-8b68-427c2a98edd0","url":"https://onlylabs.fyi/signals/af78f536-671b-45a1-8b68-427c2a98edd0","source_url":"https://www.amazon.science/blog/a-kernel-centric-path-to-real-time-video-generation-on-trainium","title":"A kernel-centric path to real-time video generation on Trainium","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"amazon","name":"Amazon (Nova)","category":"frontier-lab"},"occurred_at":"2026-09-25T14:55:00+00:00","first_seen_at":"2026-09-25T20:00:50.870264+00:00","date_source":"rss.item_date"},{"id":"b1f0a245-4fb7-4ce3-9fc9-d6f27c67626a","url":"https://onlylabs.fyi/signals/b1f0a245-4fb7-4ce3-9fc9-d6f27c67626a","source_url":"https://www.amazon.science/news/amazon-launches-research-initiative-with-stanford-university-to-advance-ai-and-science","title":"Amazon launches research initiative with Stanford University to advance AI and science","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"amazon","name":"Amazon (Nova)","category":"frontier-lab"},"occurred_at":"2026-09-21T19:31:59+00:00","first_seen_at":"2026-09-21T20:00:49.304769+00:00","date_source":"rss.item_date"},{"id":"6110800b-299d-42e5-976e-ca048fbabdd7","url":"https://onlylabs.fyi/signals/6110800b-299d-42e5-976e-ca048fbabdd7","source_url":"https://www.amazon.science/blog/advancing-ai-for-biology-teaching-models-to-design-and-characterize-antibodies","title":"Advancing AI for biology: Teaching models to design and characterize antibodies","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"amazon","name":"Amazon (Nova)","category":"frontier-lab"},"occurred_at":"2026-09-21T17:51:00+00:00","first_seen_at":"2026-09-21T20:00:49.304769+00:00","date_source":"rss.item_date"},{"id":"b8ac5bf9-eb1b-41ff-bb48-617db6a218b4","url":"https://onlylabs.fyi/signals/b8ac5bf9-eb1b-41ff-bb48-617db6a218b4","source_url":"https://www.amazon.science/blog/why-dont-machine-learning-research-agents-overfit","title":"Why don’t machine learning research agents overfit?","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"amazon","name":"Amazon (Nova)","category":"frontier-lab"},"occurred_at":"2026-09-10T15:03:39+00:00","first_seen_at":"2026-09-10T16:00:49.125365+00:00","date_source":"rss.item_date"},{"id":"b95008f2-e0cc-424f-9821-d57ec87074a5","url":"https://onlylabs.fyi/signals/b95008f2-e0cc-424f-9821-d57ec87074a5","source_url":"https://www.amazon.science/blog/developing-provably-correct-rust-code-with-verus","title":"Developing provably correct Rust code with Verus","context":null,"kind":{"key":"post_published","label":"Writing"},"org":{"slug":"amazon","name":"Amazon (Nova)","category":"frontier-lab"},"occurred_at":"2026-08-31T15:35:33+00:00","first_seen_at":"2026-08-31T16:01:44.985787+00:00","date_source":"rss.item_date"}]}
