工作流可以自我进化了，英伟达开源 SoL-Pi，每小时省13.5刀！

TL;DR - NVIDIA open-sourced SoL-Pi, an agent harness that automatically optimizes coding-agent workflows to reduce redundant reasoning, context, and tool-output overhead. Across 535 test environments, it reportedly cut token use by up to 64% and API costs by up to 54% while maintaining baseline task performance.

• SoL-Pi emerged from an automated research loop that evaluated 152 AI-generated workflow optimizations and retained four effective mechanisms.
• Its core techniques are action fusion, online context compression, indexed “observation packages” for tool outputs, and evidence-linked log summarization using cheaper models.
• The evaluation included 495 historical bugs from open-source repositories and 40 open-ended sandbox tasks with programmatic verification.
• Compared with the Pi agent base, SoL-Pi used 45%–49% fewer tokens and reduced development costs by roughly one-third.
