JIT-Agent Dynamically Generates Harnesses to Boost Model Performance
omarsar0 · x · 2026-08-28
JIT-Agent is a model whose output is an agent harness. It formalizes the harness as a composable four-module protocol (memory, planning, action, tools) and synthesizes one on the fly. It also repairs harnesses mid-execution. Tests show DeepSeek-V4-Flash with JIT-Agent surpassed GPT-5.6 on DeepSearchQA, and GLM-5.2 gained up to +20.2 points.
