About

TensorZero built an open-source LLMOps platform that unified an LLM gateway, observability, evaluation, optimization, and experimentation into a single system, powering approximately 1% of global LLM API spend at its peak. The platform enabled a data and learning flywheel for optimizing LLM applications, turning production inference data into improved models and prompts. TensorZero also developed Autopilot, an automated AI engineer that analyzes LLM observability data and automatically optimizes prompts and models. The company raised $7.3M in seed funding in 2024 and a $15M Series A in 2025, but archived its GitHub repository in June 2026 and the product is no longer maintained.
