TensorZero

TensorZero is an open-source platform designed to provide production-grade infrastructure for large language model (LLM) applications. It features a unified API that enables seamless access to multiple LLM providers with minimal latency, along with tools for observability, optimization, evaluation, and experimentation. TensorZero is completely self-hosted and free to use, allowing developers to build and enhance their LLM applications with capabilities such as A/B testing and automatic fallbacks. Backed by a team of experienced engineers and researchers, TensorZero aims to empower users to leverage real-world data to create smarter and more efficient AI models.
