LangSmith Fine-Tuning enters public beta: turn traces into fine-tuned models via smithtune CLI
LangChain · x · 2026-09-25
- LangChain launched LangSmith Fine-Tuning in public beta, handling the entire fine-tuning process: it turns your LangSmith traces into a fine-tuning dataset to train specialized models that cut cost and latency.
- The open-source CLI smithtune trains on Baseten Loops and deploys the finished checkpoint to Baseten with one command.
- Core idea: reuse existing production traces to distill workflow-specific smaller models without hand-building training data.
