On-Demand Attention aims to balance long context and speed
A publication dated September 20, 2026 describes On-Demand Attention, which uses a lightweight head to trigger full context when needed, aiming to speed decoding while recovering much of the performance lost with local attention.

What happened and what to do
On September 20, 2026, a publication about On-Demand Attention described training a lightweight head to decide when to trigger full context. The text says the approach speeds decoding with long contexts and recovers much of the performance lost with local attention, aiming to balance efficiency and quality.
A company running models on long inputs can assess this strategy using its own documents and tasks: measure latency, cost, and response quality, comparing full-context use with local attention. An evaluation and monitoring pipeline can record these results and inform configuration and deployment decisions, without assuming the technique is suitable before testing.
