What is TensorZero?
Build industrial-grade LLM applications: one API for every LLM, observability, optimization (prompts, models, etc.), evaluations, and A/B testing — all open source. Turn metrics and human feedback into smarter, faster, and cheaper LLMs. Get started in minutes.
Problem
Users managing multiple LLM APIs and tools face integration challenges, lack of observability, and difficulty optimizing prompts/models, leading to higher costs and slower iteration.
Solution
An open-source stack that provides a unified API for LLMs, enabling observability, optimization, evaluations, and A/B testing to improve performance and cost efficiency.
Customers
Developers and data scientists building enterprise LLM applications, particularly in AI-first tech companies or teams scaling LLM deployments.
Unique Features
End-to-end platform combining model orchestration with built-in analytics, human feedback integration, and optimization workflows for industrial LLM pipelines.
