TensorZero Review: An Open-Source LLMOps Stack for Production AI
Building an LLM demo is easy compared with operating one. Once an application reaches users, teams need to know which model handled a request, how long it took, what it cost, whether the answer was useful and what changed after a prompt or provider update. TensorZero tries to bring those concerns into one open-source system. Its scope is ambitious: gateway, observability, evaluation, experimentation and optimization. That can reduce fragmentation, but it also creates a platform that must be designed and operated carefully. What TensorZero is TensorZero sits between an application and model providers. Requests pass through a common gateway that can route across supported services and self-hosted inference systems. The same platform records structured inference data, supports evaluations and experiments, and connects production feedback to later prompt or model improvements. The project is provider-agnostic rather than tied to one commercial API. This is useful when teams want fallback r...
