Fireworks says it is a launch training partner for LangSmith Fine-Tuning and smithtune

Fireworks says it is a launch training partner for LangChain’s LangSmith Fine-Tuning and smithtune. It describes a workflow that takes LangSmith traces into managed SFT on Fireworks, followed by evaluation and deployment, using one CLI and no separate training infrastructure.

The steps use a Fireworks API key from Fireworks API keys and the smithtune CLI in the smithtune repository.
