Optimization Studio Use Cases

Optimize Your RAG

Better Routing for your Agents

Improve Categorization Accuracy

Structured Vibe-Checking

Build Reliable Custom Evals

Safety and Compliance

Improve performance of your RAG by letting LangWatch find the best prompt and demonstrations to return the right documents when generating a search query.

Then, reduce hallucinations by optimizing the prompt to maximize faithfulness score when answering the user.
