next-plaid makes late-interaction exact rescoring nearly free with one int8 op, 6x speedup

lateinteraction · x · 2026-09-03

Developer chaochunh nearly eliminated the slow half of PLAID-style late-interaction search — exact rescoring — in next-plaid 1.7.0 using a single int8 operation. It works on existing indexes, runs CPU-only, and the benchmark shows the once-dominant "decompress" segment is gone, delivering a 6x speedup. The library underpins ColGREP, and the work drew praise from search community members.
