Swapping RLM sub-calls for Jev: half the cost, 6x faster at 1M tokens

lateinteraction · x · 2026-10-16

A weekend experiment replaced Recursive Language Models' sub-calls with Jev, a System One model returning calibrated probabilities. On OOLONG at 1M tokens, RLM+Jev is half the cost and 6x faster than Haiku 5.5 sub-calls while holding scores, while full-context reads get expensive and degrade. The thread also covers abstention behavior, routing to bigger models, and where the setup didn't help.
