Frequently Asked Questions

What are the pricing options for TensorZero?
TensorZero is open-source and free to use. You only pay for the underlying LLM APIs and infrastructure costs you choose to integrate with the framework.
How steep is the learning curve for getting started?
Setup requires familiarity with Python and MLOps concepts, but the framework includes documentation and examples to guide integration. The learning curve is moderate for teams with ML infrastructure experience.
What LLM providers and APIs does TensorZero integrate with?
TensorZero provides a gateway layer that connects to major LLM providers like OpenAI, Anthropic, and others through unified APIs. It also supports custom integrations via its extensible architecture.
What is the main limitation of TensorZero?
As an open-source tool, it requires in-house deployment and maintenance expertise. It's best suited for teams with dedicated ML infrastructure resources rather than those seeking fully managed solutions.
What is the ideal use case for TensorZero?
TensorZero is ideal for teams building production LLM applications who need fine-grained control over model selection, experimentation, observability, and optimization in a single framework.
