LangWatch is a monitoring, evaluation, and optimization platform designed for large language models (LLM). It measures LLM quality using scientific methods, automatically discovers the best prompts and models, and provides an intuitive analytics dashboard, enabling AI teams to deliver high-quality products at ten times the speed. Key advantages of LangWatch include reduced manual optimization, enhanced development efficiency, assured product quality and security, and compliance with enterprise-level data control. The product leverages Stanford's DSPy framework, assisting users in finding suitable prompts or models within minutes instead of weeks, thereby accelerating the transition of products from proof-of-concept to production.
