Unlimited OCR Cuts Thick-Document KV Cache from 47GB to 1.77GB

xiaohu · x · 2026-10-27

Follow-up from the Wenxin Unlimited OCR Gen 2 thread: the model splits thick documents into parts, keeping only what's needed for the current section and releasing stale caches — cutting this cache's VRAM usage from 47GB to 1.77GB in tests.

Bonus: the name nods to Fate/stay night's "Unlimited Blade Works". After Gen 1, a community member rewrote its famous incantation for OCR ("pixels for body, tokens for blood..."), which the team loved enough to put at the start of the Gen 2 tech report.
