TensorZero unveils an open‑source LLMOps stack that bundles a gateway, observability, evaluation, optimization, and experimentation into a single Rust‑based service. The gateway delivers <1 ms p99 latency over 10k+ QPS, letting teams call any major LLM provider through one API.

The platform stores every inference, feedback, and metric in the user’s database, exposing them via a UI or programmatic API. Users can benchmark prompts with heuristics or LLM judges, run A/B tests, and auto‑optimize prompts with the new Autopilot feature.

With support for Anthropic, OpenAI, Azure, and dozens of others, TensorZero powers roughly 1 % of global LLM API spend and scales from startup prototypes to Fortune 10 deployments. Operators can adopt the gateway incrementally, then layer observability and experimentation as needed.
