What is LangWatch?

LangWatch is a platform focused on optimizing Language Model applications (LLMs). It facilitates AI teams to smooth out quality assurance, thus increasing the speed of shipping. By leveraging Stanfords DSPy framework, LangWatch helps to automatically discover the best prompts and models. It also provides a drag and drop feature enabling collaboration among team members. Apart from these features, LangWatch provides an intuitive analytics dashboard for monitoring and evaluation purposes. The optimization studio is designed to ensure continual progress. The platform replaces manual work with the ability to find the right prompt or model in a fraction of the standard time. LangWatch allows not just developers but also domain experts from various fields such as Legal, Sales, Customer Services, HR, Health and Finance to be part of the process. Quality, assurance, latency, and cost are all measurable factors within the LangWatch system. It also enables debugging of messages and outputs. One of the key features includes versioned experiments to keep track of best performing pipelines, prompts and models. Another feature is full dataset management to facilitate collaboration and set quality standards. LangWatch supports full compatibility with all LLM models and optimizers including the DSPy framework. Users can visually track optimization progress using the LangWatch DSPy Visualizer for efficient use of AI in production.
