Models Learn to Choose Where to Attend
π‘A model-driven way to cut long-context attention costs by up to 52% with modest accuracy loss.
β‘ 30-Second TL;DR
What Changed
The protocol uses three modes: global, focus, and local attention.
Why It Matters
Declarative Attention could lower inference cost and latency for long-context applications without requiring a separate relevance-scoring model. Its practical value will depend on reliability, especially when the model declares an overly narrow context region.
What To Do Next
Prototype Declarative Attention with a long-context model and measure KV-cache reads, latency, and answer accuracy on your own retrieval workloads.
Key Points
- β’The protocol uses three modes: global, focus, and local attention.
- β’The inference engine parses model declarations like tool calls and skips unnecessary KV-cache reads.
- β’Zero-shot tests showed substantial reductions in attended tokens with modest accuracy losses.
- β’The approach is intrinsic because the model itself identifies where attention is needed.
