TensorZero
4.0Open-source infrastructure for production LLM applications: gateway, observability, optimization, and evaluation tools.
About
As large language model (LLM) applications continue to evolve at a rapid pace, developers face a host of complex challenges when moving from prototype validation to stable, efficient production deployment—including monitoring, management, optimization, and evaluation. TensorZero was built to address these challenges head-on. It is an open-source infrastructure suite designed specifically for production environments, providing powerful gateway, observability, optimization, and evaluation tools that help teams seamlessly bridge the gap between experimentation and production.
