Nvidia's SoL-Pi system cuts coding agent token usage nearly in half by optimizing the harness

The Decoder · Sep 26, 2026, 10:30 AM UTC

SoL-Pi cuts coding agents' token usage by up to 49 percent with little change in performance by optimizing the control layer between the model and its environment. A research agent tested 152 approaches across more than 3,000 runs to develop the system, though the gains were smaller on other benchmarks.…
