From Infinite Context to Linear Regression: MIT’s Attention Matching Accelerates KV Compression 100×

MIT’s new “Fast KV Compaction via Attention Matching” paper reformulates the costly KV‑cache compression problem as a series of closed‑form linear‑regression tasks, eliminating gradient descent, cutting compression time by two orders of magnitude and achieving up to 200× overall reduction while preserving accuracy on long‑context benchmarks.
