NVIDIA's SoL-Pi Slashes Agent API Costs 33% with Recursive Self-Improvement
NVIDIA and Song Han's team open-source SoL-Pi, an automated research system that discovers four reusable harness optimizations—Action Fusion, Online Context Compact, ObservationPack, and Evidence-Preserving Reducer—cutting token usage by up to 49% and API costs by 33% while retaining over 93% task performance on EdgeBench and transferring gains to other benchmarks and multi-agent clusters.
