LangWatch FAQ

How does LangWatch ensure the quality of RAG (Retrieval Augmented Generation) systems?

LangWatch provides specific capabilities for evaluating RAG quality, allowing teams to define custom evaluations and run simulations to test the retrieval and generation components, ensuring accuracy and relevance in responses.

Can LangWatch be used to test multimodal AI agents, specifically those involving voice interactions?

Yes, LangWatch supports testing multimodal agents, including those that process voice. The platform allows for agent simulations that can incorporate and evaluate the performance of these complex interactions.

What is the process for converting production traces into reusable test cases within LangWatch?

LangWatch's dataset management feature enables teams to convert production traces into reusable test cases, golden datasets, and benchmarks. This allows for continuous improvement and powers experiments, regressions, and fine-tuning of AI models.

How does LangWatch integrate with existing AI development frameworks and tools?

LangWatch is designed for seamless integration with any LLM app, agent framework, or model. It is OpenTelemetry native and offers SDKs for Python and TypeScript, supporting frameworks like OpenAI agents, LiteLLM, DSPy, LangGraph, LangChain, Pydantic AI, and AWS BedRock, among others.

What kind of security measures does LangWatch offer to protect against AI-specific vulnerabilities?

LangWatch includes 'Safeguards' designed to address AI-specific vulnerabilities such as jailbreaking/prompt injection, PII detection and auto-redaction, competitor blocklist, off-topic evaluation, and content moderation, providing custom guardrails for AI agent safety.

Does LangWatch offer self-hosting options for organizations with strict data privacy or regulatory requirements?

Yes, LangWatch provides self-hosted deployment options for organizations requiring full control over their data, especially those with high volume or privacy-sensitive data.
