LangChain 发布 LangSmith Fine-Tuning 与 smithtune CLI
LangChain 推出 LangSmith Fine-Tuning 和 smithtune CLI,可从 LangSmith 轨迹生成数据集、在 Fireworks 或 Baseten 上训练并评估微调模型。smithtune 目前支持监督微调(SFT),训练走 LoRA,无需自行管理 GPU 或训练基础设施。官方实测中,Qwen-3.8-27B 经 SFT 后 F1 从 48.9% 升至 53.7%,模型调用减少 29.8%、工具请求减少 29.4%。

ned on your examples can often perform as well as or better than a general purpose frontier model on specified tasks, often at lower cost and latency. Try LangSmith Fine-Tuning on GitHub and have your coding agent drive the fine-tuning process end to end by installing the smithtune skill from the repository. One of the biggest drivers of fine-tuning gains is data selection. With the launch of smithtune, it’s easier to connect that loop — from curated production traces in LangSmith to managed tra
